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…
Synergies between Roman Galactic Plane Survey and other major surveys
Katarzyna Kruszyńska, Rachel A. Street, Steven Gough-Kelly +15
Nancy Grace Roman Space Telescope will revolutionize our understanding of the Galactic Bulge with its Galactic Bulge Time Domain survey. At the same time, Rubin Observatories's Leg…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Uncovering the Invisible: A Study of Gaia18ajz, a Candidate Black Hole Revealed by Microlensing
K. Howil, Ł. Wyrzykowski, K. Kruszyńska +30
Identifying black holes is essential for comprehending the development of stars and uncovering novel principles of physics. Gravitational microlensing provides an exceptional oppor…
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…
Lens mass estimate in the Galactic disk extreme parallax microlensing event Gaia19dke
M. Maskoliūnas, Ł. Wyrzykowski, K. Howil +74
We present the results of our analysis of Gaia19dke, an extraordinary microlensing event in the Cygnus constellation that was first spotted by the {\gaia} satellite. This event fea…
Gaia Data Release 3: All-sky classification of 12.4 million variable sources into 25 classes
Lorenzo Rimoldini, Berry Holl, Panagiotis Gavras +31
Gaia DR3 contains 1.8 billion sources with G-band photometry, 1.5 billion of which with BP and RP photometry, complemented by positions on the sky, parallax, and proper motion. The…
Early recognition of Microlensing Events from Archival Photometry with Machine Learning Methods
I. Gezer, Ł. Wyrzykowski, P. Zieliński +6
Gravitational microlensing method is a powerful method to detect isolated black holes in the Milky Way. During a microlensing event brightness of the source increases and this feat…
Single-lens mass measurement in the high-magnification microlensing event Gaia19bld located in the Galactic disc
K. A. Rybicki, Ł. Wyrzykowski, E. Bachelet +66
We present the photometric analysis of Gaia19bld, a high-magnification () microlensing event located in the southern Galactic plane, which exhibited finite source and m…
Lens parameters for Gaia18cbf -- a long gravitational microlensing event in the Galactic plane
Katarzyna Kruszyńska, Ł. Wyrzykowski, K. A. Rybicki +29
Context: The timescale of a microlensing event scales as a square root of a lens mass. Therefore, long-lasting events are important candidates for massive lenses, including black h…
Gaia Photometric Science Alerts
S. T. Hodgkin, D. L. Harrison, E. Breedt +108
Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims: We pr…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
