A Method to Measure the Unbiased Decorrelation Timescale of the AGN Variable Signal from Structure Functions
Szymon Kozłowski
A simple, model-independent method to quantify the stochastic variability of active galactic nuclei (AGNs) is the structure function (SF) analysis. If the SF for the timescales sho…
The OGLE Collection of Variable Stars. Eclipsing Binaries in the Magellanic System
M. Pawlak, I. Soszyński, A. Udalski +10
We present the collection of eclipsing binaries in the Large and Small Magellanic Clouds, based on the OGLE survey. It contains 48605 systems, 40204 belonging to the LMC and 8401 t…
Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
Gaia and Variable Stars
A. Udalski, I. Soszyński, D. M. Skowron +9
We present a comparison of the Gaia DR1 samples of pulsating variable stars - Cepheids and RR Lyrae type - with the OGLE Collection of Variable Stars aiming at the characterization…
Limitations on the recovery of the true AGN variability parameters using Damped Random Walk modeling
Szymon Kozłowski
Context: The damped random walk (DRW) stochastic process is nowadays frequently used to model aperiodic light curves of AGNs. A number of correlations between the DRW model paramet…
OGLE-2015-BLG-0196: Ground-based Gravitational Microlens Parallax Confirmed By Space-Based Observation
C. Han, A. Udalski, A. Gould +20
In this paper, we present the analysis of the binary gravitational microlensing event OGLE-2015-BLG-0196. The event lasted for almost a year and the light curve exhibited significa…
