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…
An Arecibo Search for Fast Radio Transients from M87
Akshay Suresh, Shami Chatterjee, James M. Cordes +1
The possible origin of millisecond bursts from the giant elliptical galaxy M87 has been scrutinized since the earliest searches for extragalactic fast radio transients undertaken i…
An Arecibo 327 MHz Search for Radio Pulsars and Bursts in the Dwarf Irregular Galaxies Leo A and T
Fronefield Crawford, Kohei Hayashi
We have conducted an Arecibo 327 MHz search of two dwarf irregular galaxies in the Local Group, Leo A and T, for radio pulsars and single pulses from fast radio bursts and other gi…
Searching For Gravitational Waves From Cosmological Phase Transitions With The NANOGrav 12.5-year dataset
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +62
We search for a first-order phase transition gravitational wave signal in 45 pulsars from the NANOGrav 12.5 year dataset. We find that the data can be modeled in terms of a strong…
Reprocessing of a Green Bank 43-meter Telescope Survey of Unidentified Bright Radio Sources for Pulsars and Radio Bursts
F. Crawford, J. Margeson, B. Nguyen +4
We have reprocessed a set of observations of 75 bright, unidentified, steep-spectrum polarized radio sources taken with the Green Bank 43-m telescope to find previously undetected…
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-…
