Astronomers discover faintest distant galaxy

Friday, June 1, 2012

Astronomers at Arizona State University have found an exceptionally distant galaxy, ranked among the top 10 most distant objects currently known in space. Light from the recently detected galaxy left the object about 800 million years after the beginning of the universe, when the universe was in its infancy.

A team of astronomers, led by James Rhoads, Sangeeta Malhotra, and Pascale Hibon of the School of Earth and Space Exploration at ASU, identified the remote galaxy after scanning a moon-sized patch of sky with the IMACS instrument on the Magellan Telescopes at the Carnegie Institution's Las Campanas Observatory in Chile.

The observational data reveal a faint infant galaxy, located 13 billion light-years away. "This galaxy is being observed at a young age. We are seeing it as it was in the very distant past, when the universe was a mere 800 million years old," says Rhoads, an associate professor in the school. "This image is like a baby picture of this galaxy, taken when the universe was only 5 percent of its current age. Studying these very early galaxies is important because it helps us understand how galaxies form and grow."

The galaxy, designated LAEJ095950.99+021219.1, was first spotted in summer 2011. The find is a rare example of a galaxy from that early epoch, and will help astronomers make progress in understanding the process of galaxy formation. The find was enabled by the combination of the Magellan telescopes' tremendous light gathering capability and exquisite image quality, thanks to the mirrors built in Arizona's Steward Observatory; and by the unique ability of the IMACS instrument to obtain either images or spectra across a very wide field of view. The research, published in the June 1 issue of The Astrophysical Journal Letters, was supported by the National Science Foundation (NSF).

This galaxy, like the others that Malhotra, Rhoads, and their team seek, is extremely faint and was detected by the light emitted by ionized hydrogen. The object was first identified as a candidate early-universe galaxy in a paper led by team member and former ASU postdoctoral researcher Hibon. The search employed a unique technique they pioneered that uses special narrow-band filters that allow a small wavelength range of light through.

A special filter fitted to the telescope camera was designed to catch light of narrow wavelength ranges, allowing the astronomers to conduct a very sensitive search in the infrared wavelength range. "We have been using this technique since 1998 and pushing it to ever-greater distances and sensitivities in our search for the first galaxies at the edge of the universe," says Malhotra, an associate professor in the school. "Young galaxies must be observed at infrared wavelengths and this is not easy to do using ground-based telescopes, since the Earth's atmosphere itself glows and large detectors are hard to make."

To be able to detect these very distant objects which were forming near the beginning of the universe, astronomers look for sources which have very high redshifts. Astronomers refer to an object's distance by a number called its "redshift," which relates to how much its light has stretched to longer, redder wavelengths due to the expansion of the universe. Objects with larger redshifts are farther away and are seen further back in time. LAEJ095950.99+021219.1 has a redshift of 7. Only a handful of galaxies have confirmed redshifts greater than 7, and none of the others is as faint as LAEJ095950.99+021219.1.

"We have used this search to find hundreds of objects at somewhat smaller distances. We have found several hundred galaxies at redshift 4.5, several at redshift 6.5, and now at redshift 7 we have found one," explains Rhoads. "We've pushed the experiment's design to a redshift of 7 ? it's the most distant we can do with well-established, mature technology, and it's about the most distant where people have been finding objects successfully up to now."

Malhotra adds, "With this search, we've not only found one of the furthest galaxies known, but also the faintest confirmed at that distance. Up to now, the redshift 7 galaxies we know about are literally the top one percent of galaxies. What we're doing here is to start examining some of the fainter ones ? thing that may better represent the other 99 percent."

Resolving the details of objects that are far away is challenging, which is why images of distant young galaxies such as this one appear small, faint, and blurry.

"As time goes by, these small blobs which are forming stars, they'll dance around each other, merge with each other and form bigger and bigger galaxies. Somewhere halfway through the age of the universe they start looking like the galaxies we see today ? and not before. Why, how, when, where that happens is a fairly active area of research," explains Malhotra.

In addition to Hibon, Malhotra, and Rhoads, the paper's authors include Michael Cooper of the University of California at Irvine, and Benjamin Weiner of the University of Arizona.

Why You Should Get Your Bathroom ... - Home Improvement Ideas

Posted by idhar on Jun 1, 2012 in Real Estate |



?Fully managing project for your bathroom from start to finish, can completely eradicate all the inconvenience of combining the planned arrival of the plumbing engineer, to correspond with the tiling firm you arranged, which must then coincide with the electrician to install the lighting. ?Selecting one company to fully manage the project removes the need for independent contractors which often can be unreliable and difficult to plan.?
From the initial planning, to incorporate everything you need, to coincide with the plumbing which may be repositioned, ensure you obtain expert guidance and a personal service to ensure your new bathroom is more than merely a room to bathe and shower, but a calming environment to unwind at the end of the day. With your choice of lighting to inset into false ceilings, or situated over mirrors for convenience, you can create the perfect place to unwind. With a wide range of options for your sanitary ware, you may possibly consider a whirlpool or jacuzzi bath or more classic designs. The choice of style and colour can be best suited to your particular taste and complimented with your preference of tiling or wall boards and bathroom accessories. Showers can be positioned over the bath in rooms with confined space, or you may consider a wet room shower or cubicle shower.?
Ordering your bathroom from a firm who also specialises in bespoke furniture and storage alternatives can give you the added advantage of including bespoke furniture into the room. This can be beneficial when space is confined to maximise the use of all space and fill any otherwise useless space and awkward corners. It is also perfect in the larger bathroom, to offer drawers and cupboards to store toiletries, bath towels and dressing gowns for your convenience. along with all bespoke designed furniture you can decide on the placement of rails, shelves and drawers to best suit your storage needs inside the room. The style of the units, again is entirely of your personal choice. High gloss or mirrored designs can be perfect in bathrooms, you can also find corresponding wall shelves or mirrors to give an individually designed look.?
Showrooms and choice of catalogues is the ideal way to fully appreciate the choice of products and the capabilities of an individually designed bathroom. Your designer should be pleased to offer all the necessary advice and their experienced bathroom advisors will measure the room and discuss your plans and thoughts, in order to ensure a specific and bespoke service through to the completion of your new bathroom.

IK Multimedia's iRing MIC Cast is now shipping for iOS devices, we go hands-on

Back at CES, IK Multimedia unveiled a trio of music / recording accessories for iDevices. One of which was the diminutive iRig MIC Cast to handle those on-the-go podcasting and voice recording duties. The outfit has announced that the ultra-compact microphone that plays nice with the iPhone, iPad and iPod touch is now shipping. Let's have a quick refresher, shall we? The kit plugs into your Apple device's 3.5mm audio jack and sports a headphone output of its own for monitoring purposes. Inside the kit, a unidirectional condenser capsule goes to work to isolate the audio you want recorded instead that pesky background chatter. If you're looking to snag one, it'll set you back $40 (€29.99) and includes a stand for your handheld inside the box. But before you take the leap, head on past the break for some of our hands-on impressions of the device.

Building molecular 'Cages' to fight disease

ScienceDaily (May 31, 2012) ? UCLA biochemists have designed specialized proteins that assemble themselves to form tiny molecular cages hundreds of times smaller than a single cell. The creation of these miniature structures may be the first step toward developing new methods of drug delivery or even designing artificial vaccines.

"This is the first decisive demonstration of an approach that can be used to combine protein molecules together to create a whole array of nanoscale materials," said Todd Yeates, a UCLA professor of chemistry and biochemistry and a member of the UCLA-DOE Institute of Genomics and Proteomics and the California NanoSystems Institute at UCLA.

Published June 1 in the journal Science, the research could be utilized to create cages from any number of different proteins, with potential applications across the fields of medicine and molecular biology.

UCLA graduate student Yen-Ting Lai, lead author of the study, used computer models to identify two proteins that could be combined to form perfectly shaped three-dimensional puzzle pieces. Twelve of these specialized pieces fit together to create a molecular cage a mere fraction of the size of a virus.

"If you just connect two random proteins together, you expect to get an irregular network," said Yeates, senior author of the study. "In order to control the geometry, the idea was to make a rigid link holding the two proteins in place as if they were parts of a toy puzzle."

The specifically designed proteins intermesh to form a hollow lattice that could act as a vessel for drug delivery, he said.

"In principle, it would be possible to attach a recognition sequence for cancer cells on the outside of the cage, with a toxin or some other 'magic bullet' contained inside," said Yeates. "That way, the drug could be delivered directly to certain targets like tumor cells."

At this stage, the assembled protein cages are porous enough that a drug placed inside would likely leak out during the delivery process, Lai said. His next project will involve constructing a new molecular cage with an interior that will be better sealed.

Another use for the versatile protein structures might be as artificial vaccines. Some traditional vaccines use an inactive surface protein from a virus to trick the body's immune system into thinking it is under attack. This method isn't always effective, because sometimes the protein in question doesn't look enough like the virus to trigger a strong response from the body's defenders.

However, by decorating the surface of a molecular cage with segments of virus-derived proteins, the tiny structures might better mimic a virus, stimulating an immune response even stronger than a traditional vaccine and better protecting the human recipient from illness.

Before these protein structures can be used in medical applications, the molecular containers themselves must be constructed from human-like proteins, rather than the currently employed bacterial proteins that the human body might immediately clear from circulation, Yeates said.

"Our first challenge will be repeating these kinds of designs with molecules that are less likely to generate a host immune response," he said. "Generally, we want to use proteins that look like human proteins so the body does not recognize them as foreign."

The idea of building complex, self-assembled protein structures has been Yeates' ambition since he published a paper outlining preliminary work on this method in 2001. Yet the concept remained on the back burner for 10 years until Yen-Ting Lai joined Yeates' research group. With three master's degrees -- in structural biology, bioinformatics and biomedical engineering -- Lai had the right combination of skills to bring the research to fruition, Yeates said.

This project is federally funded by the National Science Foundation. Other co-authors include UCLA senior staff scientist Duilio Cascio.

A second breakthrough

A second paper co-authored by Yeates creates similarly designed molecular cages using multiple copies of the same protein as building blocks. The scientists control the shape of the cage by computing the sequence of amino acids necessary to link the proteins together at the correct angles. The research, also published May 31 in Science, resulted from a collaboration between the UCLA team and professor David Baker at the University of Washington.

This alternative method represents a more versatile approach because it requires only one type of protein to form a structure, Yeates said. However, devising different kinds of links between the identical proteins remains a major challenge. Lead author Neil King, a postdoctoral scholar at the University of Washington and a former student of Yeates, took the numerous computer-generated possibilities and tested each version experimentally until he found one which produced the right behavior.

This research is federally funded by the National Institutes of Health and the U.S. Department of Energy. Other UCLA co-authors include senior staff researcher Michael Sawaya.

More Details about back up generators here.

Tweet This The technique of the machines for property use is notably simple along with being not really a complicated thing as many people think about.

Generators with regard to home make use of are typically referred to as the reassurance generators that provide enough electricity to run the domestic appliances at the time of power outage. The reasoning behind is whenever the power outage occur the tripper switch on the generator activated and that start doing work, providing alternative power source for any appliances and that means you would not suffer the pain of the electricity shortage troubles.

Once if you installed a standby generator in your home, it monitors an important power supply that you recieve regularly. Once the electricity goes down the semi-automatic or fully automatic switch activated in order that it diverts the most crucial power source with the backup generator to your home appliances. But this procedure would not training with the portable machines as they have to connect personally and needs a kick to get started functioning.

When power outage occur the rule is sent and also the generator starts functioning providing power for the home appliances. Just as the same on starting approach it monitors the main power utility and once if the main electricity electrical power recieved it send the signal so the automatic tripper switch triggers and diverts the backup generators power with the main electricity utility. This process will be continue as long as the generator utility is with the kitchen appliances.

This process happens which has no initiative because of you since it was semi-automatic or fully automatic. Also there will be no power requirements for the generator to make sure that there is no need for want you to rush so as to fill the fuel during the time of power outage.

However there are plenty of advantages can be there to find benefited at the time of main power interruption, these machineries has to be maintained within a good issue accordingly.
