On Bimodality in the Eccentricity Distribution of Galactic Double Neutron Stars
Aldana Grichener, Paul Disberg, Ryosuke Hirai +1
The detection of Galactic double neutron stars (DNSs) through pulsar timing offers a unique opportunity to probe massive stellar and binary evolution. The observed DNS population e…
Reconciling the Systemic Kicks of Observed Millisecond Pulsars, Spider Pulsars, and Low-mass X-ray Binaries
Paul Disberg, Arash Bahramian, Ilya Mandel
Millisecond pulsars (MSPs) have been proposed as evolutionary products of low-mass X-ray binaries (LMXBs) through a stage in which they are spider pulsars (i.e., redbacks and black…
The maximum offsets of binary neutron star mergers from host galaxies
Ilya Mandel, Om Sharan Salafia, Andrew Levan +1
We analytically derive, and illustrate with a population synthesis model, the maximum offset of binary neutron star mergers ejected from their host galaxies. This approximate maxim…
The metallicity dependence of long-duration gamma-ray bursts
Paul Disberg, Anne Lankreijer, Martyna ChruÅliÅska +5
Both theoretical models and observations of collapsar created gamma-ray bursts -- typically long-duration gamma-ray bursts (LGRBs) -- suggest that these transients cannot occur at…
The Kick Velocity Distribution of Isolated Neutron Stars
Paul Disberg, Ilya Mandel
Neutron stars (NSs) are thought to receive natal kicks at their formation in supernovae. In order to investigate the magnitude of these kicks, we analyze the proper motions and dis…
A kinematically constrained kick distribution for isolated neutron stars
Paul Disberg, Nicola Gaspari, Andrew J. Levan
The magnitudes of the velocity kicks that neutron stars (NSs) obtain at their formation have long been a topic of discussion. In previous work, a novel method was proposed to deter…
