  • 14 pulsars in NGC 1851 using MeerKAT

    We report the discovery of 13 new pulsars in the globular cluster NGC 1851 by the TRAPUM Large Survey Project using the MeerKAT radio telescope. The discoveries consist of six...
  • Nulling of 20 pulsars

    Most of pulsar nulling observations were conducted at frequencies lower than 1400MHz. We aim to understand the nulling behaviors of pulsars at relatively high frequency, and to...
  • LOFAR census of non-recycled pulsars sample

    We present the results from the low-frequency (40-78MHz) extension of the first pulsar census of non-recycled pulsars carried out with the LOw-Frequency ARray (LOFAR). We used...
  • Crystallization of neutron star outer crust

    The interior of a neutron star is usually assumed to be made of cold catalyzed matter. However, the outer layers are unlikely to remain in full thermodynamic equilibrium during...
  • LOTAAS pulsar discoveries

    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...
  • HESS J1825-137 particle transport

    We present a detailed view of the pulsar wind nebula (PWN) HESS J1825--137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting...
  • Dynamic spectra of 10 pulsars

    Pulsars scintillate. Dynamic spectra show brightness variation of pulsars in the time and frequency domain. Secondary spectra demonstrate the distribution of fluctuation power...
  • LOFAR census of non-recycled pulsars

    We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations Dec>8{deg} and Galactic...
  • Crab pulsar 50-400GeV light curve

    The Crab pulsar is the only astronomical pulsed source detected at very high energy (VHE, E>100GeV) gamma rays. The emission mechanism of VHE pulsation is not yet fully...
  • PSR J1048-5832 V and R images

    PSR J1048-5832 is a young radio-pulsar that has recently been detected in {gamma}-rays with Fermi, and also in X-rays with Chandra and XMM-Newton. It powers a compact pulsar...
  • WDA and WDB apsidal-motion constants

    The internal structure constants k_j_ and the radius of gyration are useful tools for investigating the apsidal motion and tidal evolution of close binaries and planetary...
  • Pulsar subpulse modulation properties at 21cm

    We present the results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands...
  • RIJ photometry of stars around PSR B1718-19

    In our paper we present VLT-observations in R, I and J of the candidate companion of PSR B1718-19, and also make use of HST observations in F702W, previously presented in Van...
  • Radial oscillations of relativistic stars

    We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive...
  • Rotating neutron stars models. I.

    (no description available)
  • New pulsar rotation measures

    We measured a sample of 150 pulsar rotation measures (RMs) using the 20-cm receiver of the Parkes 64-m radio telescope. 46 of the pulsars in our sample have not had their RM...
  • Pulsar glitches

    We study the expectancy of large glitches ({Delta}{Omega}/{Omega}>10^-7) from a sample of 430 pulsars other than the Vela pulsar. The pulsars in this sample have exhibited 19...
  • Galactic X-ray Pulsars

    This catalog contains data on the Galactic population of 82 confirmed X-ray pulsars in high-mass X-ray binary (HMXB) systems, classified into 18 persistent and 64 transient...
  • Galactic X-ray pulsars

    Catalog of Galactic population of persistent and transient X-ray pulsars in HMXB systems
