A Gravitationally Lensed Quasar Discovered in OGLE
Z. Kostrzewa-Rutkowska, S. Kozłowski, C. Lemon +15
We report the discovery of a new gravitationally lensed quasar (double) from the Optical Gravitational Lensing Experiment (OGLE) identified inside the 670 sq. deg area encomp…
OGLE-2014-SN-131: A long-rising Type Ibn supernova from a massive progenitor
E. Karamehmetoglu, F. Taddia, J. Sollerman +11
Type Ibn supernovae (SNe Ibn) are thought to be the core-collapse explosions of massive stars whose ejecta interact with He-rich circumstellar material (CSM). We report the discove…
The evolution of superluminous supernova LSQ14mo and its interacting host galaxy system
T. -W. Chen, M. Nicholl, S. J. Smartt +26
We present and analyse an extensive dataset of the superluminous supernova (SLSN) LSQ14mo (z = 0.256), consisting of a multi-colour lightcurve from -30 d to +70 d in the rest-frame…
OGLE16aaa - a Signature of a Hungry Super Massive Black Hole
Łukasz Wyrzykowski, M. Zieliński, Z. Kostrzewa-Rutkowska +22
We present the discovery and first three months of follow-up observations of a currently on-going unusual transient detected by the OGLE-IV survey, located in the centre of a galax…
Massive stars exploding in a He-rich circumstellar medium. V. Observations of the slow-evolving SN Ibn OGLE-2012-SN-006
A. Pastorello, L. Wyrzykowski, S. Valenti +36
We present optical observations of the peculiar Type Ibn supernova (SN Ibn) OGLE-2012-SN-006, discovered and monitored by the OGLE-IV survey, and spectroscopically followed by PESS…
Optical counterparts of ROSAT X-ray sources in two selected fields at low vs. high Galactic latitudes
J. Greiner, G. A. Richter
The optical identification of large number of X-ray sources such as those from the ROSAT All-Sky Survey is challenging with conventional spectroscopic follow-up observations. We in…
A hot Jupiter transiting a mid-K dwarf found in the pre-OmegaCam Transit Survey
J. Koppenhoefer, R. P. Saglia, L. Fossati +13
We describe the pre-OmegaTranS project, a deep survey for transiting extra-solar planets in the Carina region of the Galactic Disk. In 2006-2008 we observed a single dense stellar…
A Systematic Search for Supersoft X-Ray Sources in the ROSAT All-Sky Survey
J. Greiner
We have conducted a systematic search for supersoft X-ray sources using the ROSAT all-sky survey data. With the optical identification of the selected sources being almost complete…
Catalog of Luminous Supersoft X-ray Sources
J. Greiner
This catalog comprises an up-to-date list of luminous (>10^36 erg/s) supersoft X-ray sources. We include in this catalog accreting binary sources of high luminosity which are thoug…
Search for GRB counterparts
J. Greiner
A state-of-the-art review is given on the search for counterparts of -ray bursts. Particular emphasis is put on the search for flaring counterparts, i.e. emission during or shor…
