SPICE -- modelling synthetic spectra of stars with non-homogeneous surfaces
M. JabÅoÅska, T. RóżaÅski, 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…
Astrometry-Only Detection of Microlensing Events with Gaia
T. JankoviÄ, A. Gomboc, Å. 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…
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…
Uncovering the Invisible: A Study of Gaia18ajz, a Candidate Black Hole Revealed by Microlensing
K. Howil, Å. Wyrzykowski, K. KruszyÅska +30
Identifying black holes is essential for comprehending the development of stars and uncovering novel principles of physics. Gravitational microlensing provides an exceptional oppor…
