The NANOGrav 15 yr Data Set: Piecewise Power-Law Reconstruction of the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +108
The NANOGrav 15-year (NG15) data set provides evidence for a gravitational-wave background (GWB) signal at nanohertz frequencies, which is expected to originate either from a cosmi…
Deep Neural Emulation of the Supermassive Black-hole Binary Population
Nima Laal, Stephen R. Taylor, Luke Zoltan Kelley +13
While supermassive black-hole (SMBH)-binaries are not the only viable source for the low-frequency gravitational wave background (GWB) signal evidenced by the most recent pulsar ti…
A Stellar Dynamical Mass Measurement of the Supermassive Black Hole in NGC 3258
Thomas K. Waters, Kayhan Gültekin, Karl Gebhardt +2
We present a stellar dynamical mass measurement of the supermassive black hole in the elliptical (E1) galaxy NGC 3258. Our findings are based on integral field unit spectroscopy fr…
Connecting Core Galaxy Properties to the Massive Black Hole Binary Population
CJ Harris, Kayhan Gultekin
We investigate how the properties of massive black hole binaries influence the observed properties of core galaxies. We compare the observed trend in stellar mass deficit as a func…
Shock-Driven Periodic Variability in a Low-Mass-Ratio Supermassive Black Hole Binary
K. Whitley, A. Kuznetsova, K. Gültekin +1
We investigate the time-varying electromagnetic emission of a low-mass-ratio supermassive black hole binary (SMBHB) embedded in a circumprimary disk, with a particular interest in…
ALMA gas-dynamical mass measurement of the supermassive black hole in the red nugget relic galaxy PGC 11179
Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh +10
We present 0-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(21) emission from the circumnuclear gas disk in the red nu…
