Sky survey reveals newborn jets in distant galaxies（图）
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...
With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a probl...
UMass Amherst Astronomers Find Unexpected,Dust-obscured Star Formation in Normal Distant Galaxy
UMass Amherst Astronomers Dust-obscured Star Formation Normal Distant Galaxy

Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, University of Massachusetts Amherst astronomer Alexandra Pope and colle...
UCLA astronomers make first accurate measurement of oxygen in distant galaxy
UCLA astronomers first accurate measurement of oxygen galaxy
2016/8/11
UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and ...
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...

Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energe...
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) -- among other telescopes -- has obtained the best view...
Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing for the first time part of the network of filaments thought to connect galaxies in a cosmic web. Resea...
The effect of the environment on the gas kinematics and the structure of distant galaxies
Galaxies: evolution -galaxies: clusters -galaxies: kinematics and dynam- ics -galaxies: structure
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...
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters I. Spectroscopic Data
Spectroscopy of Luminous Compact Blue Galaxies in Distant Clusters I. Spectroscopic Data
2011/10/17
We used the DEIMOS spectrograph on the Keck II Telescope to obtain spectra of galaxies in the fields of five distant, rich galaxy clusters over the redshift range 0.5 < z < 0.9 in a search for luminou...
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...
Interpretation of the Global Anisotropy in the Radio Polarizations of Cosmologically Distant Sources
Polarization—magnetic fields—galaxies active—galaxies high-redshift—cosmology miscellaneous—elementary particles
2010/9/16
We present a detailed statistical study of the observed anisotropy in radio polarizations from distant extragalactic objects. This anisotropy was earlier found by Birch (1982) and reconfirmed by Jain ...
