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 …

The birth of gravitational wave astronomy was triggered by the first detection of a signal
produced by the merger of two compact objects (also known as a compact binary …

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 …

To date, the LIGO and Virgo observatories have made detections of numerous sources of
gravitational radiation. These detections have been of transient gravitational waves (GWs) …

In this work, we investigate the tidal deformability of a neutron star admixed with dark matter,
modeled as a massive, self-interacting, complex scalar field. We derive the equations to …

Continuous gravitational waves (CWs) are quasi-monochromatic signals expected to be
ever-present in the data of gravitational-wave (GW) detectors such as Advanced LIGO (Aasi …

In this paper, we study compact binary millisecond pulsars with low-and very low-mass
companion stars (spiders) in the Galactic field, using data from the latest Gaia data release …

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 …

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 …

The optical study of the heated substellar companions of black widow (BW) millisecond
pulsars (MSPs) provides unique information on the MSP particle and radiation output and on …
