Chandra X-ray Observations of Quasars with Velocity-Offset Broad Lines: Assessing the Binary Supermassive Black Hole Hypothesis

Peter Breiding, Michael Eracleous, Tamara Bogdanović +2

During the final stages of a galaxy merger, dynamical friction acting on the supermassive black holes (SMBHs) in the post-merger remnant can lead to the formation of a gravitationa…

XRISM/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region

E. Kammoun, T. Kawamuro, K. Murakami +48

We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…

BASS LII: The prevalence of double-peaked broad lines at low accretion rates among hard X-ray selected AGN

Charlotte Ward, Michael J. Koss, Michael Eracleous +18

A fraction of active galactic nuclei (AGN) have double-peaked H, H and Mg II broad lines attributed to emission from rotating gas in the accretion disk. Using optical spectro…

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217

The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…

A NuSTAR Census of the X-ray Binary Population of the M31 Disk

Hannah Moon, Daniel R. Wik, V. Antoniou +11

Using hard (E>10 keV) X-ray observations with NuSTAR, we are able to differentiate between accretion states, and thus compact object types, of neutron stars and black holes in X-ra…

A Panchromatic Study of the X-ray Binary Population in NGC 300 on Sub-Galactic Scales

Breanna A. Binder, Rosalie Williams, Jacob Payne +3

The population-wide properties and demographics of extragalactic X-ray binaries (XRBs) correlate with the star formation rates (SFRs), stellar masses (), and environment…
