In the CDM model of structure formation, a stellar spheroid grows by the assembly of smaller galaxies, the so-called building blocks. Combining the Munich-Groningen semi-analyti…
The OmegaWhite Survey for short period variable stars II: An overview of results from the first four years
Ruxandra Toma, Gavin Ramsay, Sally MacFarlane +7
OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is…
The Chandra Galactic Bulge Survey: optical catalogue and point-source counterparts to X-ray sources
T. Wevers, S. T. Hodgkin, P. G. Jonker +12
As part of the Chandra Galactic Bulge Survey (GBS), we present a catalogue of optical sources in the GBS footprint. This consists of two regions centered at Galactic latitude b = 1…
UVES and X-Shooter spectroscopy of the emission line AM CVn systems GP Com and V396 Hya
T. Kupfer, D. Steeghs, P. J. Groot +3
We present time-resolved spectroscopy of the AM CVn-type binaries GP Com and V396 Hya obtained with VLT/X-Shooter and VLT/UVES. We fully resolve the narrow central components of th…
