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…
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…
