Luminosity and stellar mass functions of disks and spheroids in the SDSS and the supermassive black hole mass function
A. J. Benson, Dajana Dzanovic, C. S. Frenk +1
Using the Galactica code of Benson et al., we obtain quantitative measurements of spheroid-to-disk ratios for a sample of 8839 galaxies observed in the Sloan Digital Sky Survey. We…
The baryon fraction of LambdaCDM haloes
Robert A. Crain, Vincent R. Eke, Carlos S. Frenk +4
We investigate the baryon fraction in dark matter haloes formed in non-radiative gas-dynamical simulations of the LambdaCDM cosmogony. By combining a realisation of the Millennium…
The spin and shape of dark matter haloes in the Millennium simulation of a LambdaCDM universe
Philip Bett, Vincent Eke, Carlos S. Frenk +3
We investigate the spins and shapes of over a million dark matter haloes identified at z=0 in the Millennium simulation. Our sample spans halo masses ranging from dwarf galaxies to…
Chandra monitoring observations of the ultraluminous X-ray source NGC 5204 X-1
T. P. Roberts, R. E. Kilgard, R. S. Warwick +2
We report the results of a 2-month campaign conducted with the Chandra X-ray observatory to monitor the ultraluminous X-ray source (ULX) NGC 5204 X-1. This was composed of a 50-ks…
Consistency of the black hole mass determination in AGN from the reverberation and the X-ray excess variance method
M. Nikolajuk, B. Czerny, J. Ziolkowski +1
Values of black hole masses are frequently determined with the help of the reverberation method. This method requires a specific geometrical factor related to the distribution of t…
