. This artistтАЩs impression shows the disk of gas and cosmic dust around the young star HD 142527. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen vast streams of gas flowing across the gap in the disk. These are the first direct observations of these streams, which are expected to be created by giant planets guzzling gas as they grow, and which are a key stage in the birth of giant planets. // Credit: ALMA (ESO/NAOJ/NRAO)/M.

... High-resolution Herschel spectroscopy reveals the proto-planetary disk around the young star T Tau N . ... A study led by Linda Podio ( AstroFIt fellow at the Arcetri Observatory) with Inga Kamp (Kapteyn Institute, the Netherlands), Claudio Codella (Observatory of Arcetri) and other collaborators from Grenoble, UK and USA, makes use of high-resolution spectroscopic observations with HIFI on board the Herschel space observatory to characterize the disk around the young star T Tau N . ...

... Previous Spitzer and IRAS observations of the LMC suggest an excess of FIR emission with respect to the gas surface density traced by 12CO rotational emission lines and H i 21 cm emission. ... Aims: Based on Herschel HERITAGE observations taken as part of the science demonstration phase, we examine the correlation between gas and dust surface densities at higher resolution than previously achieved. ... Dust surface density maps were derived from the HERITAGE data. ...

... ALMA has the potential to detect and resolve CO rotational line emission in debris disks, potentially providing key information to determine its provenance. " " (e.g. LTE, CO/H2 abundance ratio) do not necessarily apply in low gas density environments such as debris disks, and can lead to orders of magnitude errors in CO mass estimations. The 3 upper limit on the total CO mass for the Fomalhaut system is of 5.8 x 10-5 Mearth. ... Different colours represent different gas kinetic temperatures. ...

... This talk focuses on exploring the connection between Ly absorbers and galaxies. The theorist view of gas in the low z universe is based on the filamentary structures that are evident in simulations based on the CDM paradigm. ... The observer's view of gas in the low-z universe is based on the Ly absorbers which have column densities as low as 10 cm , while galaxies are at column densities of 10 cm . ... The absorber has N cm . ... Can examine LSS defined by gas-rich galaxies around absorbers. ...

... Their large amounts of dust make them ideal objects to study how dust forms in the high-redshift interstellar medium (ISM), and to study the interplay between star formation activity, gas and dust. Up until recent interferometric observations with PdBI and ALMA, the full characterisation of SMGs had been hindered by the large beams of single-dish observations that made it challenging to identify their optical and infrared counterparts. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... The fact that the Sun is a gas, however, lets different regions pass by one another fluidly. ... This differential rotation has interesting ramifications for the Sun's magnetic field. ... This bizarre distortion of the magnetic field results in active phenomena on the surface of the Sun. ... Magnetic instabilities in the solar field cause short, violent ejections of gas called solar flares-the most explosive events on the Sun. ... The Sun can also be viewed safely through special types of filters. ...
