The Gaia/IPHAS and Gaia/KIS Value-Added Catalogues

S. Scaringi, C. Knigge, J. E. Drew +7

We present a sub-arcsecond cross-match of Gaia DR2 against the INT Photometric H-alpha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2) and the Kepler-INT Survey (K…

A powerful flare from Sgr A* confirms the synchrotron nature of the X-ray emission

G. Ponti, E. George, S. Scaringi +21

We present the first fully simultaneous fits to the NIR and X-ray spectral slope (and its evolution) during a very bright flare from Sgr A*, the supermassive black hole at the Milk…

A persistent ultraviolet outflow from an accreting neutron star binary transient

N. Castro Segura, C. Knigge, K. S. Long +31

All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…

Kepler observations of the eclipsing cataclysmic variable KIS J192748.53+444724.5

S. Scaringi, P. J. Groot, M. Still

We present results from long cadence Kepler observations covering 97.6 days of the newly discovered eclipsing cataclysmic variable KIS J192748.53+444724.5/KIC 8625249. We detect de…

Triggering micronovae through magnetically confined accretion flows in accreting white dwarfs

S. Scaringi, P. J. Groot, C. Knigge +5

Rapid bursts at optical wavelengths have been reported for several accreting white dwarfs, where the optical luminosity can increase by up to a factor 30 in less than an hour fadin…

Fourier time lags in the dwarf nova SS Cygni

E. Aranzana, S. Scaringi, E. Körding +2

To understand the physical processes governing accretion discs we can study active galactic nuclei (AGN), X-ray binary systems (XRBs) and cataclysmic variables (CVs). It has been s…
