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…
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…
Refined Mass and Geometric Measurements of the High-Mass PSR J0740+6620
Emmanuel Fonseca, H. Thankful Cromartie, Timothy T. Pennucci +42
We report results from continued timing observations of PSR J0740+6620, a high-mass, 2.8-ms radio pulsar in orbit with a likely ultra-cool white dwarf companion. Our data set consi…
Reactivation of the high-magnetic field pulsar PSR J1846--0258 with magnetar-like bursts
Harsha Blumer, Samar Safi-Harb, Maura A. McLaughlin +1
We report on the 2020 reactivation of the energetic high-magnetic field pulsar PSR J1846-0258 and its pulsar wind nebula (PWN) after 14 years of quiescence with new Chandra and Gre…
The Green Bank Northern Celestial Cap Pulsar Survey. VI. Timing and Discovery of PSR J1759+5036: A Double Neutron Star Binary Pulsar
Gabriella Agazie, Michael Mingyar, Maura McLaughlin +27
The Green Bank North Celestial Cap (GBNCC) survey is a 350-MHz all-sky survey for pulsars and fast radio transients using the Robert C. Byrd Green Bank Telescope. To date, the surv…
