ISW in CDM or something else?
Andrzej M. Sołtan
We investigate a correlation between the Planck's CMB temperature map and statistics based on the space density of quasars in the SDSS catalogue. It is shown that the amplitude of…
Topology of large scale under-dense regions
A. M. Sołtan
We investigate the large scale matter distribution adopting QSOs as matter tracer. The quasar catalogue based on the SDSS DR7 is used. The void finding algorithm is presented and s…
Galaxy clustering using photometric redshifts
A. M. Soltan, M. J. Chodorowski
We investigate the evolution of the galaxy two point correlation function (CF) over a wide redshift range, 0.2 < z < 3. For the first time the systematic analysis covers the redshi…
What X-ray source counts can tell about large-scale matter distribution
A. M. Soltan, M. J. Chodorowski
Sources generating most of the X-ray background (XRB) are dispersed over a wide range of redshifts. Thus, statistical characteristics of the source distribution carry information o…
The nearest neighbor statistics for X-ray source counts II. Chandra Deep Field South
A. M. Soltan
It is assumed that the unresolved fraction of the X-ray background (XRB) consists of a truly diffuse component and a population of the weak sources below the present detection thre…
The nearest neighbor statistics for X-ray source counts I.The method
Andrzej M. Sołtan
Most of the X-ray background (XRB) is generated by discrete X-ray sources. It is likely that still unresolved fraction of the XRB is composed from a population of the weak sources…
