Three-Dimensional Distributions of Type II Cepheids and Anomalous Cepheids in the Magellanic Clouds. Do these Stars Belong to the Old, Young or Intermediate-Age Population?
P. Iwanek, I. Soszyński, D. Skowron +8
The nature of type II Cepheids and anomalous Cepheids is still not well known and their evolutionary channels leave many unanswered questions. We use complete collection of classic…
Discovery of two quasars at from the OGLE Survey
Szymon Kozłowski, Eduardo Bañados, A. Udalski +16
We have used deep Optical Gravitational Lensing Experiment (OGLE-IV) images ( mag, mag at ) of the Magellanic System, encompassing an area of $\s…
OGLE Collection of Galactic Cepheids
A. Udalski, I. Soszyński, P. Pietrukowicz +10
We present here a new major part of the OGLE Collection of Variable Stars - OGLE Collection of Galactic Cepheids. The new dataset was extracted from the Galaxy Variability Survey i…
Rotation curve of the Milky Way from Classical Cepheids
P. Mroz, A. Udalski, D. M. Skowron +7
Flat rotation curves of spiral galaxies are considered as an evidence for dark matter, but the rotation curve of the Milky Way is difficult to measure. Various objects were used to…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
The OGLE Collection of Variable Stars. Type II Cepheids in the Magellanic System
I. Soszyński, A. Udalski, M. K. Szymański +10
We present a nearly complete collection of type II Cepheids in the Magellanic System. The sample consists of 338 objects: 285 and 53 variables in the Large and Small Magellanic Clo…
