Soft X-ray background fluctuations and large-scale structure in the Universe
F. J. Carrera, A. C. Fabian, X. Barcons
We have studied the fluctuations of the soft (0.9-2 keV) X-ray background intensity for ~10 arcmin and ~2 arcmin beam sizes, using 80 high galactic latitude medium-deep images from…

Soft versus Hard X-ray emission in AGN: partial covering and warm plus cold absorber models
M. Teresa Ceballos, Xavier Barcons
We analyse the ROSAT PSPC hardness ratio and the 0.5-2 keV to 2-10 keV flux ratio of 65 Active Galactic Nuclei (AGN) for which there are both ROSAT archival observations available…

The Luminosity Function Evolution of Soft X--ray selected AGN in the RIXOS survey
M. J. Page, F. J. Carrera, G. Hasinger +7
A sample of 198 soft X--ray selected active galactic nuclei (AGN) from the ROSAT International X--ray Optical Survey (RIXOS), is used to investigate the X--ray luminosity function…
