Gamma-ray and radio populations of millisecond pulsars in globular clusters
Hannah Lawson, Duncan R. Lorimer
The populations of millisecond pulsars (MSPs) across the Milky Way's globular cluster (GC) system serve as powerful diagnostics of neutron star evolution in a variety of dense stel…
Pulsars in Globular Clusters With the SKAO
M. Bagchi, F. Abbate, V. Balakrishnan +14
Globular clusters (GCs) are highly efficient factories of radio pulsars: per unit of stellar mass, they contain about 1000 times more pulsars than in the Galactic field. Thus far,…
Understanding the Neutron Star Population with the SKAO Telescopes
L. Levin, M. Bagchi, M. Burgay +12
The known population of non-accreting neutron stars is ever growing and currently consists of more than 3500 sources. Pulsar surveys with the SKAO telescopes will greatly increase…
Gravitational Wave Measurement of the - Intrinsic Scatter at High Redshift
Cayenne Matt, Kayhan Gültekin, Gabriella Agazie +109
The observed GWB spectrum is higher in amplitude than model predictions by a factor of 2-3. Using a semi-analytic model, we evaluate the effect of a high-scatter supermassive black…
The NANOGrav 15-Year Data Set: A Case Study for Simplified Dispersion Measure Modeling for PSR J1455-3330 and the Impact on Gravitational Wave Sensitivity
Michael T. Lam, David L. Kaplan, Gabriella Agazie +46
Evidence for a low-frequency gravitational-wave background using pulsar timing arrays has generated recent interest into its underlying contributing sources. However, multiple inve…
The RRATalog: a Galactic census of rotating radio transients
Devansh Agarwal, Evan F. Lewis, Duncan R. Lorimer +4
Rotating radio transients (RRATs) represent a significant but poorly understood component of the Galactic neutron star population, characterized by sporadic emission first detectab…
