Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

We describe Keck-telescope spectrophotometry and imaging of the companion of the" black
widow" pulsar PSR J0952− 0607, the fastest known spinning neutron star (NS) in the disk of …

Fewer than a dozen gamma-ray pulsars were known when the Fermi Gamma-ray Space
Telescope was launched on 2008 June 11, and the extent and diversity of the population …

The object FRB 20180916B is a well-studied repeating fast radio burst source. Its proximity
(∼ 150 Mpc), along with detailed studies of the bursts, has revealed many clues about its …

We present an overview of the LOFAR Tied-Array All-Sky Survey (LOTAAS) for radio pulsars
and fast transients. The survey uses the high-band antennas of the LOFAR Superterp, the …

We present the discovery of a new optical/X-ray source likely associated with the Fermi γ-ray
source 4FGL J1408. 6–2917. Its high-amplitude periodic optical variability, large …

The population of millisecond pulsars (MSPs) has been expanded considerably in the last
decade. Not only is their number increasing, but also various classes of them have been …

More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of
gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of …

In agreement with the constantly increasing gravitational wave events, new aspects of the
internal structure of compact stars can be considered. A scenario in which a first-order …

Black widows are extreme millisecond pulsar binaries where the pulsar wind ablates their
low-mass companion stars. In the optical range, their light curves vary periodically due to the …
