Detecting Gravitational Scattering of Interstellar Objects Using Pulsar Timing
Ross J. Jennings, James M. Cordes, Shami Chatterjee
Gravitational scattering events, in which the path of an interstellar object is deflected by a pulsar or the solar system, give rise to reflex motion which can potentially be detec…
The NANOGrav 11-Year Data Set: Evolution of Gravitational Wave Background Statistics
J. S. Hazboun, J. Simon, S. R. Taylor +60
An ensemble of inspiraling supermassive black hole binaries should produce a stochastic background of very low frequency gravitational waves. This stochastic background is predicte…
Eight Millisecond Pulsars Discovered in the Arecibo PALFA Survey
E. Parent, V. M. Kaspi, S. M. Ransom +18
We report on eight millisecond pulsars (MSPs) in binary systems discovered with the Arecibo PALFA survey. Phase-coherent timing solutions derived from 2.5 to 5 years of observation…
Fast Radio Bursts: An Extragalactic Enigma
James M. Cordes, Shami Chatterjee
We summarize our understanding of millisecond radio bursts from an extragalactic population of sources. FRBs occur at an extraordinary rate, thousands per day over the entire sky w…
VLA Observations of Single Pulses from the Galactic Center Magnetar
R. S. Wharton, S. Chatterjee, J. M. Cordes +6
We present the results of a 7-12 GHz phased-array study of the Galactic center magnetar J1745-2900 with the Karl G. Jansky Very Large Array (VLA). Using data from two 6.5 hour obse…
The Event Horizon General Relativistic Magnetohydrodynamic Code Comparison Project
Oliver Porth, Koushik Chatterjee, Ramesh Narayan +25
Recent developments in compact object astrophysics, especially the discovery of merging neutron stars by LIGO, the imaging of the black hole in M87 by the Event Horizon Telescope (…
Fast Radio Burst Tomography of the Unseen Universe
Vikram Ravi, Nicholas Battaglia, Sarah Burke-Spolaor +13
The discovery of Fast Radio Bursts (FRBs) at cosmological distances has opened a powerful window on otherwise unseen matter in the Universe. In the 2020s, observations of …
