Long-Term X-Ray spectral variability of the radio-loud NLS1 galaxy PKS 0558-504
M. Gliozzi, I. E. Papadakis, W. Brinkmann
We present X-ray observations of the Narrow-Line Seyfert 1 galaxy PKS 0558-504 obtained with RXTE during a 1-year monitoring campaign. This source, which is one of the very few rad…
The stellar mass content of distant galaxy groups
Michael L. Balogh, Dave Wilman, Robert D. E. Henderson +8
We have obtained near-infrared imaging of 58 galaxy groups, in the redshift range 0.1<z<0.6, from the William Herschel Telescope and from the Spitzer IRAC data archive. The groups…
Warm-Hot Intergalactic Medium Associated with the Coma Cluster
Yoh Takei, J. Patrick Henry, Alexis Finoguenov +4
We present our XMM-Newton RGS observations of X Comae, an AGN behind the Coma cluster. We detect absorption by NeIX and OVIII at the redshift of Coma with an equivalent width of 3.…
