Timing of Seven Isolated Pulsars in the Globular Cluster Terzan 1
Justine Singleton, Megan DeCesar, Shi Dai +5
Globular clusters host large populations of millisecond pulsars (MSPs) due to their high gravitational encounter rates, producing many binary systems and thus MSPs via the recyclin…
The NANOGrav 15-year Data Set: Bayesian Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96
Evidence for a low-frequency stochastic gravitational wave background has recently been reported based on analyses of pulsar timing array data. The most likely source of such a bac…
Key Science Goals for the Next Generation Very Large Array (ngVLA): Update from the ngVLA Science Advisory Council (2024)
David J. Wilner, Brenda C. Matthews, Brett McGuire +32
In 2017, the next generation Very Large Array (ngVLA) Science Advisory Council, together with the international astronomy community, developed a set of five Key Science Goals (KSGs…
Inferring Mbh-Mbulge Evolution from the Gravitational Wave Background
Cayenne Matt, Kayhan Gultekin, Luke Kelley +104
We test the impact of an evolving supermassive black hole (SMBH) mass scaling relation (Mbh-Mbulge) on the predictions for the gravitational wave background (GWB). The observed GWB…
The Green Bank North Celestial Cap Pulsar Survey. V. Pulsar Census and Survey Sensitivity
Alexander McEwen, Renee Spiewak, Joseph Swiggum +23
The Green Bank North Celestial Cap (GBNCC) pulsar survey will cover the entire northern sky () at 350 MHz, and is one of the most uniform and sensitive all-sky pulsa…
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…
Discovery and Timing of the First Millisecond Pulsar in NGC 6316
Deven Bhakta, Scott M. Ransom, Megan DeCesar +1
NGC 6316 is a poorly studied, distant, and massive globular cluster (GC) with prominent gamma-ray emission detected via the \textit{Fermi} Large Area Telescope (LAT). Based on gamm…
Two New Black Widow Millisecond Pulsars In M28
Andrew Douglas, Prajwal Padmanabh, Scott Ransom +18
We report the discovery of two Black Widow millisecond pulsars in the globular cluster M28 with the MeerKAT telescope. PSR J18242452M (M28M) is a 4.78-ms pulsar in a hou…
The Third Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
David A. Smith, Philippe Bruel, Colin J. Clark +156
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio…
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…
