The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release
Julia Blex, Moritz Hackstein, Christian Westhues +6
The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a -wide stripe in the southern Galactic disk with simultaneous observations in and …
Dust Reverberation of 3C273: torus structure and lag -- luminosity relation
Catalina Sobrino Figaredo, Martin Haas, Michael Ramolla +7
We monitored the z=0.158 quasar 3C273 between 2015 and 2019 in the optical (BVrz) and near-infrared (JHK) with the aim to perform dust reverberation mapping. Accounting for host ga…
Optical continuum photometric reverberation mapping of the Seyfert-1 galaxy Mrk509
F. Pozo Nuñez, N. Gianniotis, J. Blex +6
We present the results of a two year optical continuum photometric reverberation mapping campaign carried out on the nucleus of the Seyfert-1 galaxy Mrk509. Specially designed narr…
Photodynamical analysis of the triply eclipsing hierarchical triple system EPIC 249432662
T. Borkovits, S. Rappaport, T. Kaye +16
Using Campaign 15 data from the K2 mission, we have discovered a triply-eclipsing triple star system: EPIC 249432662. The inner eclipsing binary system has a period of 8.23 days, w…
Simultaneous H alpha and dust reverberation mapping of 3C120: Testing the bowl-shaped torus geometry
Michael Ramolla, Martin Haas, Christian Westhues +8
At the Universitaetssternwarte Bochum near Cerro Armazones we have monitored the Seyfert-1 galaxy 3C 120 between September 2014 and March 2015 in BVRI and a narrow band filter cove…
