Multi-epoch Detection of an Ultra-fast Inflow in ESP 39607: Evidence for an Accretion Cascade
Alessandro Peca, Michael J. Koss, Roberto Serafinelli +10
We present simultaneous XRISM, XMM-Newton, and NuSTAR observations of ESP 39607, a Seyfert 2 galaxy at . XRISM/Resolve reveals two absorption features near 4.7 and 4.9 k…
Implications of Non-equatorial Relativistic Accretion Flows for Ultra-Fast Inflows in AGNs
Keigo Fukumura, Alessandro Peca, Roberto Serafinelli +1
Motivated by a number of X-ray observations of active galactic nuclei (AGNs) that exhibit a potential signature of ultra-fast inflows (UFIs), we consider in this work a scenario th…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
NuSTAR Detection of an Absorption Feature in ESP 39607: Evidence for an Ultra-Fast Inflow?
Alessandro Peca, Michael J. Koss, Roberto Serafinelli +4
We report the serendipitous discovery of an absorption feature at 4.8 keV in the NuSTAR spectra of ESP 39607, a Seyfert 2 galaxy at , observed in May 2023 and August 202…
Stripe 82X Data Release 3: Multiwavelength Catalog with New Spectroscopic Redshifts and Black Hole Masses
Stephanie M. LaMassa, Alessandro Peca, C. Megan Urry +10
We present the third catalog release of the wide-area (31.3 deg) Stripe 82 X-ray survey. This catalog combines previously published X-ray source properties with multiwavelength…
X-ray properties and obscured fraction of AGN in the J1030 Chandra field
Matilde Signorini, Stefano Marchesi, Roberto Gilli +13
The 500ks Chandra ACIS-I observation of the field around the quasar SDSS J1030+0524 is currently the 5th deepest extragalactic X-ray survey. The rich multi-band coverage o…
