Interpreting the relationship between galaxy luminosity, color, and environment
galaxy luminosity color environment
2014/12/24
We study the relationship between galaxy luminosity, color, and environment in a cosmological simulation of galaxy formation. Using a simple prescription to assign colors and luminosities to simulated...
Probing Very Bright-End of Galaxy Luminosity Function at z >~ 7 Using Hubble Space Telescope Pure Parallel Observations
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We report the first results from the Hubble Infrared Pure Parallel Imaging Extragalactic Survey, which utilizes the pure parallel orbits of the Hubble Space Telescope to do deep imaging along a large ...
Eegular Articles Galaxy Luminosity Function: A New Analytic Expression
a new analytic approximation the luminosity function of galaxies the Schechter function
2010/10/19
We propose a new analytic approximation for the luminosity function of galaxies. The suggested expression behaves like the Schechter function at the faint end (φ ∼ Lα) but departs considerably a...
