  • Title: Bang Goes the Theory Zooms in on Herschel ATLAS Results | Herschel ATLAS
    Descriptive info: Fri, 08/26/2011 - 10:11.. Herschel ATLAS scientists will appear on episode 5 of BBC's.. Bang Goes the Theory.. to talk about their exciting results using the.. The team get a chance to showcase their discovery of a new, efficient way to find "cosmic zoom lenses" which allow us to peer into distant galaxies invisible to telescopes like the Hubble Space Telescope.. The show will feature an online interview with Dr Mattia Negrello of the Open University (and lead researcher on lensing project) and an interview with Dr Asantha Cooray of the University of California, Irvine.. H-ATLAS's Dr Stephen Serjeant of the Open University is also lead science consultant for the.. series.. This discovery is so interesting because Herschel is incredibly successful at finding these magnified, distant galaxies.. Negrello and his team used the zoom lenses to peer into these far-away galaxies and found that they are forming lots of stars and are extremely dusty, in fact the dust is so thick, we cannot see the galaxies at all using optical telescopes like Hubble.. In a similar way to using a magnifying glass to find tiny insects in the dirt, with the Herschel zoom  ...   finding lenses which are used at visible and radio wavelengths.. The online interview with Dr Negrello can be found.. Left: Dr Asantha Cooray in front of a Herschel image - each dot is a galaxy and there are literally thousands of galaxies in this picture.. Dr Cooray commented, "Locating new lenses is an arduous task that involves slogging through tons of data.. With Herschel, we can find a lot of them much more efficiently.. " He added, "I was surprised to learn that Herschel is so good at finding these cosmic lenses.. ".. The episode will be aired on Monday 12 Sept 19.. 30 BBC1 (England) and on BBC2 (Scotland and Wales).. Viewers in Northern Ireland can see the programme on Friday 16 Sept 20.. 30 BBC1, and the episode will be available on.. BBC iPlayer..

  • Title: Andromeda-like galaxy spied from afar with Herschel-ATLAS | Herschel ATLAS
    Descriptive info: Fri, 05/13/2011 - 22:41.. The Herschel ATLAS is a large survey ideally suited for finding rare objects and distant galaxies but sometimes, we see more normal spiral galaxies in the nearby Universe.. In this large Herschel map (below), amongst the thousands of dots (which are dusty distant galaxies), Herschel spies a spiral galaxy just like our nearest neighbour Andromeda.. Inset, we zoom  ...   the optical image (left).. The Herschel image is made up of the three SPIRE wavelengths combined, the bluer areas show hotter dust, and the red regions are from cooler dust.. The dusty spiral arms are clearly seen.. The optical image shows the light from stars, whereas the dust shows the light from dust, where the next generation of stars are being born..

  • Title: Herschel digs up the dirt on distant galaxies using cosmic zoom lenses | Herschel ATLAS
    Descriptive info: Thu, 11/04/2010 - 14:13.. The magnification allows astronomers to see galaxies otherwise hidden from us when the Universe was only a few billion years old.. This provides key insights into how galaxies have changed over the history of the cosmos.. Herschel looks at far-infrared light, which is emitted not by stars, but by the gas and dust from which they form.. Every schoolchild is taught that light travels in straight lines – but a century ago Albert Einstein showed that gravity can cause light to bend.. The effect is normally extremely small, and it is only when light passes close to a very massive object such as a galaxy containing hundreds of billions of stars that the results become easily noticeable.. When light from a very distant object passes a galaxy much closer to us, its path can be bent in such a way that the image of the distant galaxy is magnified and distorted.. These alignment events are called “gravitational lenses” and many have been discovered over recent decades, mainly at visible and radio wavelengths.. As with a normal glass lens the alignment is crucial, requiring the position of the lens – in this case a galaxy – to be just right.. This is very rare and astronomers have to rely on chance alignments, often involving sifting through large amounts of data from telescopes.. Most methods of searching for gravitational lenses have a very poor success rate with fewer than one in ten candidates typically being found to be real.. Herschel’s panoramic imaging cameras have allowed astronomers to find examples of these lenses by scanning large areas of the sky in far-infrared and sub-millimetre light.. These results are from the very first data taken as part of the “Herschel-ATLAS” project, the largest imaging survey conducted so far with Herschel, and are published in the prestigious scientific journal Science.. Dr Mattia Negrello.. , of the Open University and lead researcher of the study, explained, "Our survey of the sky looks for sources of sub-millimetre light.. The Herschel-ATLAS images contain thousands of galaxies, most so far away that the light has taken billions of years to reach us.. Dr Negrello and his team investigated.. five surprisingly bright objects.. in this small patch of sky.. Looking at the positions of these bright objects with optical telescopes on the Earth, they found galaxies that would not normally be bright at the far-infrared wavelengths observed by Herschel.. This led them to suspect that the galaxies seen in visible light might be gravitational lenses magnifying much more distant galaxies seen by  ...   observed by optical telescopes such as the W.. M.. Keck Observatory on Hawaii, shown in blue.. The light from the distant galaxy has been travelling for 11 billion years, allowing astronomers to observe the precursors to galaxies like our own in the very early Universe.. The effect of the gravitational lensing can be used to work out the structure of both galaxies, probing the formation of stars and galaxies billions of years ago and the role of mysterious Dark Matter in the relatively nearby Universe.. The magnification provided by these cosmic zoom lenses allows astronomers to study much fainter galaxies, and in more detail than would otherwise be possible.. They are the key to understanding how the building blocks of the Universe have changed since they were in their infancy.. Professor Rob Ivison.. of the Royal Observatory, Edinburgh, part of the team that created the images, said “This relatively simple technique promises to unlock the secrets of how galaxies like our Milky Way formed and evolved.. Not only does the lensing allow us to find them very efficiently, but it helps us peer within them to figure out how the individual pieces of the jigsaw came together, back in the mists of time”.. Dr Loretta Dunne.. of Nottingham University and joint-leader of the Herschel-ATLAS survey said, “What we’ve seen so far is just the tip of the iceberg.. Wide area surveys are essential for finding these rare events and since Herschel has only covered one thirtieth of the entire Herschel-ATLAS area so far, we expect to discover hundreds of lenses once we have all the data.. Once found, we can probe the early Universe on the same physical scales as we can in galaxies next door.. Professor Steve Eales.. from Cardiff University and the other leader of the survey added: “We can also use this technique to study the lenses themselves.. This is exciting because 80% of the matter in the Universe is thought to be dark matter, which does not absorb, reflect or emit light and so can’t be seen directly with our telescopes.. With the large number of gravitational lenses that we’ll get from our full survey, we’ll really be able to get to grips with this hidden Universe.. The data from the area of sky used for this work has now been released to the astronomical community.. Loretta Dunne said ”We hope that now astronomers not directly involved in H-ATLAS will dive into this data set and exploit the wealth of science which is bursting to be done with it..

  • Title: First data release of the Herschel ATLAS | Herschel ATLAS
    Descriptive info: First data release of the Herschel ATLAS.. Sun, 10/24/2010 - 15:49.. The Science Demonstration Phase (SDP) data from Herschel-ATLAS has been released to the astronomical community.. This represents the largest public release of Herschel data so far and will be a powerful data-set for studies of galaxy evolution.. Maps of 16 square degrees of sky in five bands (100, 160, 250, 350 and 500 microns) will be available for download along with the catalogues generated by the.. H-ATLAS team.. These catalogues contain 6800 sources and also provide information about the optical counterparts for 2400 galaxies which have reliable identifications in the Sloan Digital Sky Survey.. Redshifts and optical magnitudes from the u-K bands are presented courtesy of the.. GAMA.. (Galaxy and Mass Assembly) team.. The H-ATLAS SDP data have so far provided exciting results in many areas of astronomy ranging from local galaxies to distant active galaxies to nearby debris disks forming planets around stars.. The power of H-ATLAS is its wide-area coverage which means we can pick up extremely rare objects as well as see many more normal galaxies closer to home.. The quality and scale of the data have been staggering and have led already to more than 20 papers on just this small patch of sky, which is only 1/30th of the final H-ATLAS area.. The team are excited about what they will find next.. "The H-ATLAS SDP data-set surpassed all our wildest expectations,  ...   to the beautiful maps we have today.. There were some glitches which meant that the standard way of doing things was removing some of our galaxies and we had to recover them.. " He added, "Every galaxy counts!".. "Herschel's instruments have an incredible build quality" said Dr Simon Dye,.. "They have survived a gruelling launch and a long journey to the telescope's observing point at 1.. 5 million kilometres away from Earth, and yet, the quality of data they are returning is as good as the quality measured in the lab.. I feel privileged to be given the opportunity to work with this dataset.. "We hope that now astronomers who are not directly involved in H-ATLAS will dive into this data-set and exploit the wealth of science which is bursting to be done with it" said Dr Loretta Dunne.. The SPIRE maps for the SDP release were made at.. (see the boxed area below from the complete GAMA 9 hour field) and the PACS maps were made by a team of institutes across the world, led by the.. Astronomy Technology Centre, Edinburgh.. The catalogues and optical associations were produced by the.. University of Nottingham.. To download our SDP catalogue go.. We have also created a.. for extracting the results, allowing quick searches by position in the Herschel ATLAS SDP map and this can be searched using an SQL query form..

  • Title: 10 years in submillimetre astronomy | Herschel ATLAS
    Descriptive info: Sun, 10/03/2010 - 10:44.. In 1998, astronomers used the SCUBA camera on the James Clerk Maxwell Telescope on Mauna Kea in Hawaii to take the deepest image of the sky using a submillimetre camera.. Looking at the same patch of sky as the famous Hubble Deep Field image (see picture below), astronomers spent 20 full nights looking at this area and they added all the data together to get the equivalent SCUBA deep field.. SCUBA's resolution is poorer than Hubble's but we can see that the blobs in the SCUBA image (from very dusty galaxies) are very different to the thousands of galaxies we see at visible wavelengths with Hubble.. After 20 long nights, we see only 5 objects in the SCUBA image, and these are thought to be very distant galaxies, much further away than most of the objects in the Hubble Deep Field.. This patch of sky is a  ...   The first 3% of H-ATLAS data has already been taken, and in this colour image of Herschel pictures taken at 250, 350 and 500um, we see at least 6000 galaxies after only 16 hours of observing with Herschel.. This image is 4 x 4 degrees across, just over 60 times the area of the full moon - and it only took Herschel 16 hours! Each pinprick is a galaxy with the brightness related to how much dust they have, and the colour of the galaxy gives an indication of how far away it is (red galaxies are further away from us than the blue ones).. The wispy blue patches are clouds of dust in our own Milky Way galaxy, and there are also a few stars with dusty debris disks in this image as well.. Comparing the scales of the images, the SCUBA map is 600 times smaller than the Herschel ATLAS!..
