Repeating microlensing events in the OGLE data
J. Skowron, L. Wyrzykowski, S. Mao +1
Microlensing events are usually selected among single-peaked non-repeating light curves in order to avoid confusion with variable stars. However, a microlensing event may exhibit a…
Self-Organizing Maps. An application to the OGLE data and the Gaia Science Alerts
Lukasz Wyrzykowski, Vasily Belokurov
Self-Organizing Map (SOM) is a promising tool for exploring large multi-dimensional data sets. It is quick and convenient to train in an unsupervised fashion and, as an outcome, it…
The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. II. Type II Cepheids and Anomalous Cepheids in the Large Magellanic Cloud
I. Soszynski, A. Udalski, M. K. Szymanski +6
In the second part of the OGLE-III Catalog of Variable Stars (OIII-CVS) we present 197 type II Cepheids and 83 anomalous Cepheids in the Large Magellanic Cloud (LMC). The sample of…
The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. I. Classical Cepheids in the Large Magellanic Cloud
I. Soszynski, R. Poleski, A. Udalski +6
We present the first part of a new catalog of variable stars (OIII-CVS) compiled from the data collected in the course of the third phase of the Optical Gravitational Lensing Exper…
Inferring statistics of planet populations by means of automated microlensing searches
M. Dominik, U. G. Jorgensen, K. Horne +17
(abridged) The study of other worlds is key to understanding our own, and not only provides clues to the origin of our civilization, but also looks into its future. Rather than in…
The Optical Gravitational Lensing Experiment. OGLE-III Photometric Maps of the Large Magellanic Cloud
A. Udalski, I. Soszynski, M. K. Szymanski +6
We present the OGLE-III Photometric Maps of the Large Magellanic Cloud. They cover about 40 square degrees of the LMC and contain mean, calibrated VI photometry and astrometry of a…
