Quasars with Periodic Variability: Capabilities and Limitations of Bayesian Searches for Supermassive Black Hole Binaries in Time-Domain Surveys

Caitlin A. Witt, Maria Charisi, Stephen R. Taylor +1

Supermassive black hole binaries (SMBHBs) are an inevitable consequence of galaxy mergers. At subparsec separations, they are practically impossible to resolve, and the most promis…

A repeating fast radio burst associated with a persistent radio source

C. -H. Niu, K. Aggarwal, D. Li +32

The dispersive sweep of fast radio bursts (FRBs) has been used to probe the ionized baryon content of the intergalactic medium, which is assumed to dominate the total extragalactic…

The NANOGrav 12.5-year data set: Search for Non-Einsteinian Polarization Modes in theGravitational-Wave Background

Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +68

We search NANOGrav's 12.5-year data set for evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity. We fi…

Characterizing the FRB host galaxy population and its connection to transients in the local and extragalactic Universe

Shivani Bhandari, Kasper E. Heintz, Kshitij Aggarwal +23

We present the localization and host galaxies of one repeating and two apparently non-repeating Fast Radio Bursts. FRB20180301A was detected and localized with the Karl G. Jansky V…

Comprehensive analysis of a dense sample of FRB 121102 bursts

Kshitij Aggarwal, Devansh Agarwal, Evan F. Lewis +5

We present an analysis of a densely repeating sample of bursts from the first repeating fast radio burst, FRB 121102. We reanalysed the data used by Gourdji et al. (2019) and detec…

The host galaxy and persistent radio counterpart of FRB 20201124A

Vikram Ravi, Casey J. Law, Dongzi Li +7

The physical properties of fast radio burst (FRB) host galaxies provide important clues towards the nature of FRB sources. The 16 FRB hosts identified thus far span three orders of…
