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…
Heliosphere Meets Interstellar Medium, in a Galactic Context
Stella Koch Ocker, James Cordes, Shami Chatterjee +8
The physical conditions within our heliosphere are driven by the Sun's motion through an evolving interstellar environment that remains largely unexplored. The next generation of o…
Disentangling Multiple Stochastic Gravitational Wave Background Sources in PTA Datasets
Andrew R. Kaiser, Nihan S. Pol, Maura A. McLaughlin +7
With strong evidence of a common-spectrum stochastic process in the most recent datasets from the NANOGrav Collaboration, the European Pulsar Timing Array (PTA), Parkes PTA, and th…
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…
