THE NATURE OF RED DWARF GALAXIES
dark matter large-scale structure of the universe
font style='font-size:12px;'>
2014/12/23
Using dark matter halos traced by galaxy groups selected from the Sloan Digital Sky Survey Data Release 4, we find that about 1/4 of the faint galaxies (0.1 Mr – 5log h> – 17.05, hereafter dwarfs) tha...
Questioning the Doppler interpretation of cosmological red shifts

2011/9/26
The Doppler interpretation of cosmological red shifts attributes these red shifts to only the relativistic Doppler effect of light coming from receding galaxies. We question this interpretation of cos...
Galaxy-galaxy lensing constraints on the relation between baryons and dark matter in galaxies in the Red Sequence Cluster Survey 2
gravitational lensing: weak - galaxies: formation - galaxies: halos

2011/10/12
We present the results of a study of weak gravitational lensing by galaxies using imaging data that were obtained as part of the second Red Sequence Cluster Survey (RCS2). In order to compare to the b...

We investigate the origin of the color-magnitude relation (CMR) observed in cluster galaxies by using a combination of a cosmological N-body simulation of a cluster of galaxies and a semi-analytic mod...

We investigate the properties of satellite galaxies that surround isolated hosts within the redshift range 0.01 < z < 0.15, using data taken as part of the Galaxy And Mass Assembly survey. Making use ...
