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…

CHIME/FRB Discovery of an Unusual Circularly Polarized Long-Period Radio Transient with an Accelerating Spin Period

Fengqiu Adam Dong, Kaitlyn Shin, Casey Law +20

We report the discovery of CHIME J1634+44, a Long Period Radio Transient (LPT) unique for two aspects: it is the first known LPT to emit fully circularly polarized radio bursts, an…

Echoes in Different Tempo: Long-Term Monitoring of Crab Echoes with CHIME

Thierry Serafin Nadeau, Marten H. van Kerkwijk, Jing Luo +4

The Crab Pulsar is known to feature plasma lensing events known as echoes. These events are characterized by additional components in the pulse profile which are produced by additi…

The NANOGrav 15-year Data Set: Search for Gravitational Wave Memory

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102

We present the results of a search for nonlinear gravitational wave memory in the NANOGrav 15-year data set. We find no significant evidence for memory signals in the dataset, with…
