SGR J1935+2154 is an extremely active magnetar and the source of the first fast radio burst in the Milky Way, characterized as a magnetar X-ray burst, but whether the temporal...

Magnetars are neutron stars that occupy the extreme end of the neutron star population, with magnetic field strengths of more than 1012G. They have been proposed as one of the...

In preparation for the release of the astrometric orbits of Gaia, Shahaf et al. (2019MNRAS.487.5610S) proposed a triage technique to identify astrometric binaries with compact...

Magnetars are neutron stars with ultrahigh magnetic fields (~10^14^-10^15^G). The magnetar SGR J1935+2154 is not only one of the most active magnetars detected so far, but also...

We report the discovery of one possible neutron star binary (P_orb_=0.8666d) by using LAMOST low-resolution spectroscopic data. The visible companion is a late A-type dwarf...

We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5yr. This source has been in quiescence since its...

Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches...

Searches for electromagnetic counterparts of gravitational-wave signals have redoubled since the first detection in 2017 of a binary neutron star merger with a gamma-ray burst,...

We present optical follow-up imaging obtained with the Katzman Automatic Imaging Telescope, Las Cumbres Observatory Global Telescope Network, Nickel Telescope, Swope Telescope,...

The Super-Kamiokande detector can be used to search for neutrinos in time coincidence with gravitational waves detected by the LIGO-Virgo Collaboration (LVC). Both low-energy...

We explore the possibility of inferring the properties of the Galactic population of neutron stars through machine learning. In particular, in this paper we focus on their...

We search for gravitational-wave transients associated with gamma-ray bursts (GRBs) detected by the Fermi and Swift satellites during the first part of the third observing run...

Multimessenger observations of the neutron star merger GW170817 and its kilonova proved that neutron star mergers can synthesize large quantities of r-process elements. If...

The X-ray symbiotic (SyXB) V934 Her = 4U1700+24 is an M giant-neutron star (NS) binary system. Employing optical and infrared radial velocities spanning 29yr combined with the...

The Fermi {gamma}-ray source 1FGL J1417.7-4407 (J1417) is a compact X-ray binary with a neutron star primary and a red giant companion in a ~5.4 days orbit. This initial...

Nearby galaxy surveys have long classified X-ray binaries (XRBs) by the mass category of their donor stars (high-mass and low-mass). The NuSTAR observatory, which provides...

A recent study of a small sample of X-ray binaries (XRBs) suggests a significant softening of spectra of neutron star (NS) binaries as compared to black hole (BH) binaries in...

Understanding the origin of energetic fast radio bursts (FRBs) has become the main science driver of recent dedicated FRB surveys powered by real-time instrumentation. Between...

Spider pulsars are millisecond pulsars in tight binary systems in which a low-mass companion star is heated and ablated by the pulsar wind. Observations of these objects allow...

We study the impact of accretion on the equation of state and on the global properties of neutron stars in the framework of the nuclear energy-density functional theory....
