The NANOGrav 15-year data set: Search for Transverse Polarization Modes in the Gravitational-Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96

Recently we found compelling evidence for a gravitational wave background with Hellings and Downs (HD) correlations in our 15-year data set. These correlations describe gravitation…

The NANOGrav 12.5-year data set: A computationally efficient eccentric binary search pipeline and constraints on an eccentric supermassive binary candidate in 3C 66B

Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +85

The radio galaxy 3C 66B has been hypothesized to host a supermassive black hole binary (SMBHB) at its center based on electromagnetic observations. Its apparent 1.05-year period an…

How to Detect an Astrophysical Nanohertz Gravitational-Wave Background

Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93

Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…

The NANOGrav 12.5-year Data Set: Search for Gravitational Wave Memory

Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +87

We present the results of a Bayesian search for gravitational wave (GW) memory in the NANOGrav 12.5-yr data set. We find no convincing evidence for any gravitational wave memory si…

The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111

The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…

The Impact of Black Hole Scaling Relation Assumptions on the Mass Density of Black Holes

Cayenne Matt, Kayhan Gültekin, Joseph Simon

We examine the effect of supermassive black hole (SMBH) mass scaling relation choice on the inferred SMBH mass population since redshift . To make robust predictions for…
