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…

Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

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 NANOGrav 15-year Data Set: Evidence for a Gravitational-Wave Background

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

We report multiple lines of evidence for a stochastic signal that is correlated among 67 pulsars from the 15-year pulsar-timing data set collected by the North American Nanohertz O…

GW190425: Observation of a Compact Binary Coalescence with Total Mass

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1199

On 2019 April 25, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9. The Virgo detector was also taking data that did not contribut…
