Context. The pulsar wind nebula (PWN) 3C 58 is one of the historical very high-energy (VHE; E> 100 GeV) γ-ray source candidates. It is energized by one of the...

The Fermi Large Area Telescope gamma-ray source 3FGL J2039.6-5618 contains a periodic optical and X-ray source that was predicted to be a 'redback' millisecond...

We present simultaneous multiwavelength observations of the 4.66 ms redback pulsar PSR J1048+2339. We performed phase-resolved spectroscopy with the Very Large...

Finding distances in astronomy is notoriously difficult. With accurate optical spectroscopy, both the distance to and extinction (reddening) of normal stars can...

We present high time resolution optical photometric data of the polar VV Puppis obtained simultaneously in three filters (u', HeII λ4686, r') with the ULTRACAM...

As part of an optical monitoring project of low-mass X-ray binaries (

We perform a wide parameter-space search for continuous gravitational waves over the whole sky and over a large range of values of the frequency and the first...

We present the first measurement of the gravitational quadrupole moment of the companion star of a spider pulsar, namely the black widow PSR J2051-0827. To this...

We simulate the characteristics of the Galactic population of radio and gamma-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially...
