Invited talk at FRAPWS 2026
Invited talk at the FRAPWS 2026 conference in Mondello, Italy.
Extracting latent representations from X-ray spectra. Classification, regression, and accretion signatures of Chandra sources
The study of X-ray spectra is crucial to understanding the physical nature of astrophysical sources. Machine learning methods can extract compact and informative representations of …
Artificial Intelligence and complex networks in multimodal X-ray astrophysics
Invited talk on the use of multimodal data in X-ray astrophysics.
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748–676
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts …

The hunt for new pulsating ultraluminous X-ray sources: A clustering approach
Context. The discovery of fast and variable coherent signals in a handful of ultraluminous X-ray sources (ULXs) points to the presence of super-Eddington accreting neutron stars, …
Multimodal multi-output ordinal regression for discovering gravitationally-lensed transients
Gravitational lenses are caused by massive astronomical objects that distort space-time, bending light. They can distort transient astrophysical events, such as supernovae (SN), …
Counting objects with multimodal multi-output ordinal regression
Talk on AI algorithms for gravitational lenses analysis.
Augmenting X-ray Astronomical Representations with Scientific Knowledge through Contrastive Learning
Astronomers have produced large multimodal datasets that include images, spectra, and time series, and that encode physical information about the observed objects. In addition, a …

A new pulsating neutron star in the Ultraluminous X-ray source NGC 4559 X7?
Ultraluminous X-ray sources (ULX) are extragalactic objects with observed X-ray luminosities largely above the Eddington limit for a 10 M⊙ black hole. Currently, it is believed …
