The NANOGrav 12.5-year Data Set: Bayesian Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries

Zaven Arzoumanian, Paul T. Baker, Laura Blecha +75

Pulsar timing array collaborations, such as the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), are seeking to detect nanohertz gravitational waves emitted…

The NANOGrav 11yr Data Set: Limits on Supermassive Black Hole Binaries in Galaxies within 500Mpc

Zaven Arzoumanian, Paul T. Baker, Adam Brazier +54

Supermassive black hole binaries (SMBHBs) should form frequently in galactic nuclei as a result of galaxy mergers. At sub-parsec separations, binaries become strong sources of low-…

The Arecibo Pisces-Perseus Supercluster Survey I: Harvesting ALFALFA

Aileen A. O'Donoghue, Martha P. Haynes, Rebecca A. Koopmann +9

We report a multi-objective campaign of targeted 21 cm HI line observations of sources selected from the Arecibo Legacy Fast ALFA (Arecibo L-band Feed Array) survey (ALFALFA) and g…

The NANOGrav 11-Year Data Set: Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries

K. Aggarwal, Z. Arzoumanian, P. T. Baker +60

Observations indicate that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, their component black holes form SMBH binaries (SMBHB…

The Arecibo Legacy Fast ALFA Survey: The ALFALFA Extragalactic HI Source Catalog

Martha P. Haynes, Riccardo Giovanelli, Brian R. Kent +22

We present the catalog of ~31500 extragalactic HI line sources detected by the completed ALFALFA survey out to z < 0.06 including both high signal-to-noise ratio (> 6.5) detections…

The NANOGrav Nine-year Data Set: Astrometric Measurements of 37 Millisecond Pulsars

Allison M. Matthews, David J. Nice, Emmanuel Fonseca +18

Using the nine-year radio-pulsar timing data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), collected at Arecibo Observatory and the Green Ba…
