Glitch activity refers to the mean increase in pulsar spin frequency per year due to rotational glitches. It is an important tool for studying super-nuclear matter using neutron...

While pulsars possess exceptional rotational stability, large-scale timing studies have revealed at least two distinct types of irregularities in their rotation: red timing...

We report on the high-precision timing of 42 radio millisecond pulsars (MSPs) observed by the European Pulsar Timing Array (EPTA). This EPTA Data Release 1.0 extends up to...

We present a search for gravitational waves from 221 pulsars with rotation frequencies >~10Hz. We use advanced LIGO data from its first and second observing runs spanning...

PSR J1306-40 is a millisecond pulsar (MSP) binary with a non-degenerate companion in an unusually long ~1.097 day orbit. We present new optical photometry and spectroscopy of...

We present integrated pulse profiles at 5GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope. Mean flux densities...

The 2004 December 27 giant {gamma}-ray flare detected from the magnetar SGR 1806-20 created an expanding radio nebula that we have monitored with the Australia Telescope Compact...

Table1 gives the NVSS radio sources around the positions of all known pulsars. This table was generated by searching NVSS catalog, and each row gives the closest source around...

We aim to search for a hidden leptonic accelerator, such as a high-E pulsar, associated with the unidentified TeV object HESS J1702-420A. We carried out a 72ks X-ray observation...

The possible presence of amorphous and heterogeneous phases in the inner crust of a neutron star is expected to reduce the electrical conductivity of the crust, with potentially...

The Crab pulsar is a bright gamma-ray source, which has been detected at photon energies up to ~1TeV. Its phase-averaged and phase-resolved gamma-ray spectra below 10GeV exhibit...

We present the second AGILE-GRID catalogue (2AGL) of gamma-ray sources in the energy range 100MeV-10GeV. With respect to previous AGILE-GRID catalogues, the current 2AGL...

Pulsar Wind Nebulae (PWNe) represent the most prominent population of Galactic very-high-energy gamma-ray sources and are thought to be an efficient source of leptonic cosmic...

We derive a new equation of state (EoS) for neutron stars (NS) from the outer crust to the core based on modern microscopic calculations using the Argonne v18 potential plus...

The accreting X-ray pulsar Her X-1 shows two types of long-term variations, both with periods of ~35 days: 1) Turn-on cycles, a modulation of the flux, with a ten-day long...

Magnetars are an extreme, highly magnetized class of isolated neutron stars whose large X-ray luminosity is believed to be driven by their high magnetic field. Study for the...

A pulsar timing system has been operating in the 18-cm band at the Urumqi Astronomical Observatory 25-m telescope since mid-1999. Frequency resolution allowing de-dispersion of...

The Parkes multi-beam pulsar survey is a sensitive survey of a strip along the Galactic plane with |b|<5{deg} and l=260{deg} to l=50{deg}. It uses a 13-beam receiver on the...

The flux densities of 235 mostly faint pulsars at 102.5MHz are presented. The observations were carried out on the very sensitive Large Phased Array of the Lebedev Institute of...

The catalogue is an up-to-date compilation of the principal observed parameters of 558 pulsars, including positions, timing parameters, pulse widths, flux densities, proper...
