The Green Bank North Celestial Cap Survey. VII. 12 New Pulsar Timing Solutions
Joseph K. Swiggum, Ziggy Pleunis, Emilie Parent +22
We present timing solutions for 12 pulsars discovered in the Green Bank North Celestial Cap (GBNCC) 350 MHz pulsar survey, including six millisecond pulsars (MSPs), a double neutro…
An unusual pulse shape change event in PSR J1713+0747 observed with the Green Bank Telescope and CHIME
Ross J. Jennings, James M. Cordes, Shami Chatterjee +41
The millisecond pulsar J1713+0747 underwent a sudden and significant pulse shape change between April 16 and 17, 2021 (MJDs 59320 and 59321). Subsequently, the pulse shape graduall…
Implementation of an efficient Bayesian search for gravitational wave bursts with memory in pulsar timing array data
Jerry Sun, Paul T. Baker, Aaron D. Johnson +2
The standard Bayesian technique for searching pulsar timing data for gravitational wave (GW) bursts with memory (BWMs) using Markov Chain Monte Carlo (MCMC) sampling is very comput…
Snowmass2021 Cosmic Frontier White Paper: Fundamental Physics and Beyond the Standard Model
Emanuele Berti, Vitor Cardoso, Zoltán Haiman +6
Gravitational wave detectors are formidable tools to explore strong-field gravity, especially black holes and neutron stars. These compact objects are extraordinarily efficient at…
Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics
Robert Caldwell, Yanou Cui, Huai-Ke Guo +34
Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture…
The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background
J. Antoniadis, Z. Arzoumanian, S. Babak +123
We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…
