SPICE -- modelling synthetic spectra of stars with non-homogeneous surfaces
M. Jabłońska, T. Różański, L. Casagrande +4
In the era of large time-domain spectro-photometric surveys, surface variations such as starspots, chemical inhomogeneities, pulsations, rotational distortions, and binary interact…
AstroLLaVA: towards the unification of astronomical data and natural language
Sharaf Zaman, Michael J. Smith, Pranav Khetarpal +8
We present AstroLLaVA, a vision language model for astronomy that enables interaction with astronomical imagery through natural dialogue. By fine-tuning the LLaVA model on a divers…
Astrometry-Only Detection of Microlensing Events with Gaia
T. Jankovič, A. Gomboc, Ł. Wyrzykowski +7
Astrometric microlensing events occur when a massive object passes between a distant source and the observer, causing a shift of the light centroid. The precise astrometric measure…
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…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
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…
Is there a nearby microlensing stellar remnant hiding in Gaia DR3 astrometry?
Maja Jabłońska, Łukasz Wyrzykowski, Krzysztof A. Rybicki +3
Massive galactic lenses with large Einstein Radii should cause a measurable astrometric microlensing effect, i.e. the light centroid shift due to the motion of the two images. Such…
