WVU astrophysicists gravitational wave search galaxy evolution and mergers
2016/4/13
On the heels of their participation in the historic research that resulted in the detection of gravitational waves, West Virginia University astrophysicists continue to plow new ground ...
Evidence of major dry mergers at M* > 2 x 10^11 Msun from curvature in early-type galaxy scaling relations?
galaxies formation

For early-type galaxies, the correlations between stellar mass and size, velocity dis-
persion, surface brightness, color, axis ratio and color-gradient all indicate that two mass scales, M∗ = ...
Electromagnetic Counterparts to Black Hole Mergers
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
During the final moments of a binary black hole (BH) merger, the gravitational wave (GW) luminosity of the system is greater than the combined electromagnetic output of the entire observable universe.
The power spectrum of the residual rotation curve velocity as a probe of past mergers
Galaxy Astrophysics (astro-ph.GA)
2010/12/27
According to the $\Lambda CDM$ cosmological framework, galaxies underwent multiple mergers in their history. In this paper we propose to use the power spectrum of the residual fluctuations of the rota...
