Sky survey newborn jets distant galaxies
2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...
I review measurements of star formation in nearby galaxies in the UV-to-FIR wavelength range, and discuss their impact on SFR determinations in intermediate and high redshift galaxy populations. Exist...

2011/9/28
With the aim of distinguishing between possible physical mechanisms acting on galaxies when they fall into clusters, we study the properties of the gas and the stars in a sample of 422 emission-line g...
Gas accretion as the origin of chemical abundance gradients in distant galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
It has recently been suggested that galaxies in the early Universe can grow through the accretion of cold gas, and that this may have been the main driver of star formation and stellar mass growth.
ZEUS-2: a second generation submillimeter grating spectrometer for exploring distant galaxies
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
ZEUS-2, the second generation (z)Redshift and Early Universe Spectrometer, like its predecessor is a moderate resolution (R~1000) long-slit, echelle grating spectrometer optimized for the detection of...
Deepest Image of Universe Yet Reveals Most Distant Galaxies Ever Found（图）
Universe Most Distant Galaxies
2010/1/11
An international team of astronomers has used the Hubble Space Telescope to take the deepest image of the universe ever, revealing the farthest and youngest known galaxies. The results, which could of...
The UK teams, one led by Andrew Bunker and Stephen Wilkins at the University of Oxford and the other by Ross McLure and Jim Dunlop at the University of Edinburgh, analysed infrared images from the new...
