Equation-of-State Constraints on the Neutron-Star Binding Energy and Tests of Binary Formation Scenarios
A. Miguel Holgado
The second supernova that forms double-neutron-star systems is expected to occur in a progenitor that is ultra-stripped due to binary interactions. Thus, the secondary neutron star…
The Role of Strong Gravity and the Nuclear Equation of State on Neutron-Star Common-Envelope Accretion
A. Miguel Holgado, Hector O. Silva, Paul M. Ricker +1
Common-envelope evolution is important in the formation of neutron star binaries within the isolated binary formation channel. As a neutron star inspirals within the envelope of a…
Dynamical Formation Scenarios for GW190521 and Prospects for Decihertz Gravitational-Wave Astronomy with GW190521-Like Binaries
A. Miguel Holgado, Alexis Ortega, Carl L. Rodriguez
The gravitational-wave (GW) detection of GW190521 has provided new insights on the mass distribution of black holes and new constraints for astrophysical formation channels. With i…
Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey
Yu-Ching Chen, Xin Liu, Wei-Ting Liao +62
Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confir…
The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +58
We search for an isotropic stochastic gravitational-wave background (GWB) in the -year pulsar timing data set collected by the North American Nanohertz Observatory for Gravit…
Modeling the uncertainties of solar-system ephemerides for robust gravitational-wave searches with pulsar timing arrays
M. Vallisneri, S. R. Taylor, J. Simon +61
The regularity of pulsar emissions becomes apparent once we reference the pulses' times of arrivals to the inertial rest frame of the solar system. It follows that errors in the de…
