Automated detection and modeling of binary microlensing events in OGLE-IV data. I. Events with well-separated bumps

R. A. P. Oliveira, R. Poleski, P. Mróz +11

Gravitational microlensing depends primarily on the lens mass and presents a larger occurrence rate in crowded regions, which makes it the best tool to uncover the initial mass fun…

Analysis of the full Spitzer microlensing sample I: Dark remnant candidates and Gaia predictions

Krzysztof A. Rybicki, Yossi Shvartzvald, Jennifer C. Yee +70

In the pursuit of understanding the population of stellar remnants within the Milky Way, we analyze the sample of microlensing events observed by the Spitzer Space Teles…

Virial Black Hole Masses for AGNs behind the Magellanic Clouds

Swayamtrupta Panda, Szymon Kozłowski, Mariusz Gromadzki +13

We use the spectroscopic data collected by the Magellanic Quasars Survey (MQS) as well as the photometric V- and I-band data from the Optical Gravitational Lensing Experiment (OGLE…

No massive black holes in the Milky Way halo

P. Mroz, A. Udalski, M. K. Szymanski +13

The gravitational wave detectors have unveiled a population of massive black holes that do not resemble those observed in the Milky Way and whose origin is debated. According to on…

Dark lens candidates from Gaia Data Release 3

K. Kruszyńska, Ł. Wyrzykowski, K. A. Rybicki +48

Gravitational microlensing is a phenomenon that allows us to observe dark remnants of stellar evolution even if they no longer emit electromagnetic radiation. In particular, it can…

Properties of the Milky Way's Old Populations Based on Photometric Metallicities of the OGLE RR Lyrae Stars

P. Pietrukowicz, A. Udalski, I. Soszynski +11

We have used photometric data on almost 91 000 fundamental-mode RR Lyrae stars (type RRab) detected by the OGLE survey to investigate properties of old populations in the Milky Way…
