To understand the physical processes governing accretion discs we can study active galactic nuclei (AGNs), X-ray binary systems (XRBs), and cataclysmic...

We present observations of rapid (sub-second) optical flux variability in V404 Cyg during its 2015 June outburst. Simultaneous three-band observations with the...

The majority of High Mass X-ray Binaries (HMXBs) behave like X-ray pulsars, revealing that they contain a magnetised neutron star. Among the four HMXBs showing...

Context. We analyse multi-colour photometric and spectroscopic observations of the young stellar object (YSO) Gaia20bdk. Aims. We aim to investigate the exact...

Context. Among known young stellar objects (YSOs), those exhibiting the most dramatic increases in brightness due to sudden increase in mass accretion rate are...

We perform N-body simulations of a minor merger between a Milky Way like galaxy and a disk-like satellite. In this set of collisionless runs we vary critical...

We study the gas distribution in the recent merger remnant NGC 3656, a perturbed elliptical. The total gaseous mass content is a few times 10^9^M_sun_. The...

GD 552 is a high proper motion star with the strong, double-peaked emission lines characteristic of the dwarf nova class of cataclysmic variable (CV) star, and...

The optical/near-infrared (OIR) region of the spectra of low-mass X-ray binaries (XBs) appears to lie at the intersection of a variety of different emission...
