The NANOGrav 12.5-year Data Set: Chromatic Noise Characterization & Mitigation with Time-Domain Kernels

Jeffrey S. Hazboun, Joseph Simon, Jeremy Baier +64

Pulsar timing arrays (PTAs) have recently entered the detection era, quickly moving beyond the goal of simply improving sensitivity at the lowest frequencies for the sake of observ…

The NANOGrav 15-Year Data Set: Improved Timing Precision With VLBI Astrometric Priors

Sofia V. Sosa Fiscella, Michael T. Lam, Gabriella Agazie +47

Accurate pulsar astrometric estimates play an essential role in almost all high-precision pulsar timing experiments. Traditional pulsar timing techniques refine these estimates by…

CHIME-o-Grav: Wideband Timing of Four Millisecond Pulsars from the NANOGrav 15-yr dataset

Gabriella Agazie, David L. Kaplan, Abhimanyu Susobhanan +50

Wideband timing of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) datasets, where a single time-of-arrival (TOA) and a single dispersion measure (DM) a…

Inferring Mbh-Mbulge Evolution from the Gravitational Wave Background

Cayenne Matt, Kayhan Gultekin, Luke Kelley +104

We test the impact of an evolving supermassive black hole (SMBH) mass scaling relation (Mbh-Mbulge) on the predictions for the gravitational wave background (GWB). The observed GWB…

The NANOGrav 15 yr Data Set: Targeted Searches for Supermassive Black Hole Binaries

Nikita Agarwal, Gabriella Agazie, Akash Anumarlapudi +116

We present the first targeted searches for continuous gravitational waves (CWs) from 114 active galactic nuclei (AGN) that may host supermassive black hole binaries, using the NANO…

The NANOGrav 15-year Data Set: Search for Gravitational Scattering of Pulsars by Free-Floating Objects in Interstellar Space

Lankeswar Dey, Ross J. Jennings, Jackson D. Taylor +48

Free-floating objects (FFOs) in interstellar spacerogue planets, brown dwarfs, and large asteroids that are not gravitationally bound to any starare expected to be ubiquitous…
