Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between
the short-and long-duration bursts at about 2 s. The progenitors of long GRBs have been …

Abstract Advanced LIGO and Advanced Virgo's newly released GWTC-2 catalog of
gravitational-wave detections offers unprecedented information about the spin magnitudes …

Advanced LIGO may be the first experiment to detect gravitational waves. Through
superradiance of stellar black holes, it may also be the first experiment to discover the QCD …

The process of superradiance can extract angular momentum and energy from astrophysical
black holes (BHs) to populate gravitationally bound states with an exponentially large …

We compare evolutionary predictions of double compact object merger rate densities with
initial and forthcoming LIGO/Virgo upper limits. We find that:(i) Due to the cosmological …

ABSTRACT Using the Very Long Baseline Array, we have measured a trigonometric
parallax for the microquasar GRS 1915+ 105, which contains a black hole and a K-giant …

We use very long baseline interferometry to measure the proper motions of three black hole
X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia …

ABSTRACT Data from the Sloan Digital Sky Survey (∼ 300,000 galaxies) indicate that
recent star formation (within the last 1 billion years) is bimodal: half of the stars form from gas …

We investigate whether stellar-mass black holes have to receive natal kicks in order to
explain the observed distribution of low-mass X-ray binaries containing black holes within …

The aim of this work is to study the imprints that different models for black hole (BH) and
neutron star (NS) formation have on the Galactic distribution of X-ray binaries (XRBs) that …
