Pulsar Searches with the SKA [PDF]

, 2017
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, already with SKA1, pulsar searches will discover enough pulsars to increase

The International Pulsar Timing Array: First Data Release [PDF]

, 2016
The highly stable spin of neutron stars can be exploited for a variety of (astro)physical investigations. In particular, arrays of pulsars with rotational periods of the order of milliseconds can be used to detect correlated signals such as those caused ...

Populating the Galaxy with pulsars I: stellar & binary evolution

, 2008
The computation of theoretical pulsar populations has been a major component of pulsar studies since the 1970s. However, the majority of pulsar population synthesis has only regarded isolated pulsar evolution.

Discovery of an optical bow-shock around pulsar B0740-28 [PDF]

, 2002
We report the discovery of a faint H-alpha pulsar wind nebula (PWN) powered by the radio pulsar B0740-28. The characteristic bow-shock morphology of the PWN implies a direction of motion consistent with the previously measured velocity vector for the ...

POLAR GAP IN THE PULSAR FORCE-FREE MAGNETOSPHERE STRUCTURE

Radio Physics and Radio Astronomy, 2015
The stationary axisymmetric force-free magnetosphere of a pulsar is considered by accounting for the polar gap and current circuit. Adjustment of the vacuum polar gap and the closing current sheet with the force-free magnetosphere of a monopolar ...

Variable Magellanic HMXB Sources versus Variable ULX Sources: Nothing to Brag about the ULX Sources

Galaxies, 2020
We carry out a meta-analysis of ultraluminous X-ray (ULX) sources that show large variabilities (by factors of >10) between their highest and lowest emission states in the X-ray energy range of 0.3–10 keV.

The LOFAR Tied-Array All-Sky Survey (LOTAAS): Survey overview and initial pulsar discoveries [PDF]

Astronomy & Astrophysics, 2019
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 dense inner part of the LOFAR core, to survey the northern sky (δ >  0°) at a
