X-ray redshifts for obscured AGN: a case study in the J1030 deep field
Alessandro Peca, Cristian Vignali, Roberto Gilli +9
We present a procedure to constrain the redshifts of obscured ( cm) Active Galactic Nuclei (AGN) based on low-count statistics X-ray spectra, which can be ado…
Accretion History of AGN III: Radiative Efficiency and AGN Contribution to Reionization
Tonima Tasnim Ananna, C. Megan Urry, Ezequiel Treister +6
The cosmic history of supermassive black hole (SMBH) growth is important for understanding galaxy evolution, reionization and the physics of accretion. Recent NuSTAR, Swift-BAT and…
The web of the Giant: spectroscopic confirmation of a Large Scale Structure around the z=6.31 quasar SDSS J1030+0524
Marco Mignoli, Roberto Gilli, Roberto Decarli +14
We report on the spectroscopic confirmation of a large scale structure around the luminous, z=6.31 QSO SDSS~J1030+0524, that is powered by a billion solar mass black hole. The stru…
Mock catalogs for the extragalactic X-ray sky: simulating AGN surveys with Athena and with the AXIS probe
Stefano Marchesi, Roberto Gilli, Giorgio Lanzuisi +8
We present a series of new, publicly available mock catalogs of X-ray selected active galactic nuclei (AGNs), non-active galaxies, and clusters of galaxies. They are based on up-to…
Probing the Milky Way's Dark Matter Halo for the 3.5 keV Line
Dominic Sicilian, Nico Cappelluti, Esra Bulbul +3
We present a comprehensive search for the 3.5 keV line, using 51 Ms of archival Chandra observations peering through the Milky Way's Dark Matter Halo from across the entirety…
Correlations between Triaxial Shapes and Formation History of Dark Matter Haloes
Erwin T. Lau, Andrew P. Hearin, Daisuke Nagai +1
The shape of dark matter haloes plays a critical role in constraining cosmology with upcoming large-scale structure surveys. In this paper, we study the correlations between the tr…
