Cosmic Rulers: Masers as Tools for Probing Structure in the Galaxy and Beyond, from AU to kpc
Kazi L. J. Rygl, Anna Bartkiewicz, Olga Bayandina +9
Maser emission provides an unique window into astronomical sources across vast spatial scales - from tens to hundreds of astronomical units around protostars and evolved stars up t…
A database of circumstellar OH masers
D. Engels, F. Bunzel
We present a new database of circumstellar OH masers at 1612, 1665, and 1667 MHz in the Milky Way galaxy. The database (version 2.4) contains 13655 observations and 2341 different…
HS1857+5144: A hot and young pre-cataclysmic variable
A. Aungwerojwit, B. T. Gaensicke, P. Rodriguez-Gil +5
We report the discovery of a new white dwarf/M dwarf binary, HS1857+5144, identified in the Hamburg Quasar Survey (HQS). Time-resolved optical spectroscopy and photometry were carr…
Dwarf novae in the Hamburg Quasar Survey: Rarer than expected
A. Aungwerojwit, B. T. Gaensicke, P. Rodriguez-Gil +12
We report the discovery of five new dwarf novae from the Hamburg Quasar Survey (HQS), and discuss the properties of the sample of dwarf novae in the HQS. The orbital periods of the…
HS2331+3905: The cataclysmic variable that has it all
S. Araujo-Betancor, B. T. Gaensicke, H. -J. Hagen +6
We report detailed follow-up observations of the cataclysmic variable HS2331+3905, identified as an emission-line object in the Hamburg Quasar Survey. An orbital period of 81.08min…
The Hamburg/RASS Catalogue of optical identifications. Northern high-galactic latitude ROSAT Bright Source Catalogue X-ray sources
F. -J. Zickgraf, D. Engels, H. -J. Hagen +2
We present the Hamburg/RASS Catalogue (HRC) of optical identifications of X-ray sources at high-galactic latitude. The HRC includes all X-ray sources from the ROSAT Bright Source C…
