Discovery of the most X-ray luminous quasar SRGE J170245.3+130104 at redshift z
G. A. Khorunzhev, A. V. Meshcheryakov, P. S. Medvedev +10
SRGE J170245.3+130104 was discovered by the eROSITA telescope aboard the SRG space observatory on March 13-15, 2020 during the first half-year scan of its all-sky X-ray survey. The…
Cosmic-ray ionisation in circumstellar discs
Marco Padovani, Alexei V. Ivlev, Daniele Galli +1
Galactic cosmic rays are a ubiquitous source of ionisation of the interstellar gas, competing with UV and X-ray photons as well as natural radioactivity in determining the fraction…
The complex galaxy cluster Abell 514: New results obtained with the XMM - Newton satellite
J. Weratschnig, M. Gitti, S. Schindler +1
We study the X-ray morphology and dynamics of the galaxy cluster Abell 514. Also, the relation between the X-ray properties and Faraday Rotation measures of this cluster are invest…
Pre-launch estimates for GLAST sensitivity to Dark Matter annihilation signals
E. A. Baltz, B. Berenji, G. Bertone +25
We investigate the sensitivity of the Gamma-ray Large Area Space Telescope (GLAST) to indirectly detect weakly interacting massive particles (WIMPs) through the -ray signal that…
Joint deprojection of Sunyaev-Zeldovich and X-ray images of galaxy clusters
S. Ameglio, S. Borgani, E. Pierpaoli +1
We present two non-parametric deprojection methods aimed at recovering the three-dimensional density and temperature profiles of galaxy clusters from spatially resolved thermal Sun…
Angular diameter distance estimates from the Sunyaev-Zel'dovich effect in hydrodynamical cluster simulations
S. Ameglio, S. Borgani, A. Diaferio +1
The angular-diameter distance D_A of a galaxy cluster can be measuread by combining its X-ray emission with the cosmic microwave background fluctution due to the Sunyaev-Zeldovich…
