X-ray analysis of the Planck-detected triplet-cluster system PLCK G334.8-38

Alexander Kolodzig, Nabila Aghanim, Marian Douspis +2

We conducted an X-ray analysis of one of the two Planck-detected triplet-cluster systems, PLCK G334.8-38.0, with a ~ks deep XMM-Newton data. We find that the system has a…

First detection of stacked X-ray emission from cosmic web filaments

H. Tanimura, N. Aghanim, A. Kolodzig +2

We report the first statistical detection of X-ray emission from cosmic web filaments in ROSAT data. We selected 15,165 filaments at 0.2<z<0.6 ranging from 30 Mpc to 100 Mpc in len…

Studying the ICM in clusters of galaxies via surface brightness fluctuations of the cosmic X-ray background

Alexander Kolodzig, Marat Gilfanov, Gert Hütsi +1

We study the surface brightness fluctuations of the cosmic X-ray background (CXB) using Chandra data of XBOOTES. After masking out resolved sources we compute the power spectrum of…

Host galaxies and large-scale structures of active galactic nuclei

Ryan C. Hickox, Stephanie M. LaMassa, John D. Silverman +1

Our understanding of the cosmic evolution of supermassive black holes (SMBHs) has been revolutionized by the advent of large multiwavelength extragalactic surveys, which have enabl…

Can AGN and galaxy clusters explain the surface brightness fluctuations of the cosmic X-ray background?

Alexander Kolodzig, Marat Gilfanov, Gert Hütsi +1

Fluctuations of the surface brightness of cosmic X-ray background (CXB) carry unique information about faint and low luminosity source populations, which is inaccessible for conven…

Probing large-scale structure with large samples of X-ray selected AGN: I Baryonic acoustic oscillations

Gert Hütsi, Marat Gilfanov, Alexander Kolodzig +1

We investigate the potential of large X-ray-selected AGN samples for detecting baryonic acoustic oscillations (BAO). Though AGN selection in X-ray band is very clean and efficient,…

AGN and QSOs in the eROSITA All-Sky Survey -- Part II: The large-scale structure

Alexander Kolodzig, Marat Gilfanov, Gert Hütsi +1

The four-year X-ray all-sky survey (eRASS) of the eROSITA telescope aboard the Spektrum-Roentgen-Gamma satellite will detect ~3 million active galactic nuclei (AGN) with a median r…

AGN and QSOs in the eROSITA All-Sky Survey -- Part I: Statistical properties

Alexander Kolodzig, Marat Gilfanov, Rashid Sunyaev +2

Context. The main element of the observing program of the Spectrum-Roentgen-Gamma orbital observatory is a four-year all-sky survey, in the course of which the entire sky will be s…
