Milky Way-like Galaxies in Early Universe Embedded in 'Super Halos'
Milky Way-like Galaxies Early Universe Embedded Super Halos
2017/3/30
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only e...
Advanced Morphological Galaxy Classification: A Comparison of Real and Simulated Galaxies
galaxies: structure — galaxies: evolution — methods: numerical
2011/10/18
Encoded within the morphological structure of galaxies are clues related to their formation and evolutionary history. Recent advances pertaining to the statistics of galaxy morphology include sophisti...
A Search for Young Stars in the S0 Galaxies of a Super-Group at z=0.37
Search S0 Galaxies Super-Group z=0.37
2011/10/12
We analyze GALEX UV data for a system of four gravitationally-bound groups at z=0.37, SG1120, which is destined to merge into a Coma-mass cluster by z=0, to study how galaxy properties may change duri...

CLASS B 1359+154：Modelling Lensing by a Group of Galaxies
Gravitational lensing multiple-imagin individual systems
2009/5/19
The recently discovered gravitationally lensed system CLASS
B1359C154 appears to have six detectable images of a single background
source at a redshift of 3:235. A group of galaxies acts as the lens...
The Tully–Fisher Relations of the Eridanus Group of Galaxies
Galaxy rotation luminosity linewidth relation galaxies groups individual Eridanus radio lines HI 21 cm-line
2010/9/17
The Tully–Fisher (TF) or the luminosity–linewidth relations of the galaxies in the Eridanus group are constructed using the HI rotation curves and the luminosities in the optical and in the near-infra...
Using X-ray observation we have obtained the deprojected gas density and temperature profiles for a sample of cluster of galaxies. We show that cool-core clusters, which are expected to be the largest...
