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…

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…

NuSTAR observations of a varying-flux quasar in the Epoch of Reionization

Lea Marcotulli, Thomas Connor, Eduardo Bañados +13

With enough X-ray flux to be detected in a 160s scan by SRG/eROSITA, the quasar CFHQS J142952+544717 is, by far, the most luminous X-ray source known at . We pres…

The NuSTAR Serendipitous Survey: the 80-month catalog and source properties of the high-energy emitting AGN and quasar population

Claire L. Greenwell, Lizelke Klindt, George B. Lansbury +32

We present a catalog of hard X-ray serendipitous sources detected in the first 80 months of observations by the Nuclear Spectroscopic Telescope Array (NuSTAR). The NuSTAR serendipi…
