Galactic Fireworks Illuminate Monster Hydrogen Blob
Galactic Fireworks Monster Hydrogen Blob
2016/9/29
An international team of researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes has discovered the power source illuminating a so-called Lyman-alpha Blob – a ra...
We report the detection of interstellar hydrogen deuteride (HD) toward the
supernova remnant IC443, and the tentative detection of HD toward the Herbig
Haro objects HH54 and HH7 and the star forming...
Powerful High-Velocity Dispersion Molecular Hydrogen Associated with an Intergalactic Shock Wave in Stephan's Quintet

2014/12/23
We present the discovery of strong mid-infrared emission lines of molecular hydrogen of apparently high-velocity dispersion (~870 km s-1) originating from a group-wide shock wave in Stephan's Quintet....
Results on the properties of warm molecular hydrogen in 57 normal galaxies are derived from measurements of H2 rotational transitions, obtained as part of SINGS. This study extends previous extragalac...
We have observed a 3° × 3° area centered on the M81/M82 group of galaxies using the Robert C. Byrd Green Bank Telescope in a search for analogs to the high-velocity clouds of neutral hydrogen found ar...
Modelling neutral hydrogen in galaxies using cosmological hydrodynamical simulations
galaxies: evolution: general ?galaxies: luminosity function, mass func-tion ?dark matter ?radio lines: galaxies ?methods: N-body simulations

The characterisation of the atomic and molecular hydrogen content of high-redshift galaxies is a major observational challenge that will be addressed over the coming years with a new generation of rad...
