Late-Time Evolution of the Massive Stellar Merger M101 OT2015-1
Marco A. Gómez-Muñoz, Nadejda Blagorodnova, Tomasz Kamiński +6
Luminous red novae (LRNe) are astronomical transients arising from unstable mass transfer and common envelope phases in close binary systems, culminating in stellar mergers. Their…
XP-TEAL: Gaia XP Tool for Emission and Absorption Lines II. Gaia-HELIX catalogue of H emitters in Gaia BP/RP spectra
S. Malhotra, M. Weiler, F. Anders +8
Context: With Gaia's third Data Release (DR3), low-resolution BP/RP (XP) spectra became available for more than 219 million sources. In previous work, we developed a fast method fo…
Cosmological Spacetimes with Sign-Changing Spatial Curvature and Topological Transitions
Gerardo García-Moreno, Bert Janssen, Alejandro Jiménez Cano +3
Observational evidence, together with practical computations and modeling, supports a Euclidean spatial sector in the current cosmological model based on the FLRW metric. This, how…
Causality as a guiding principle for physics beyond General Relativity
Gerardo García-Moreno
This thesis is situated within the context of quantum gravity, broadly understood as any effort to explore the interplay between gravitation and the quantum realm, without necessar…
Analysis of mass-transferring binary candidates in the Milky Way
G. Garcia-Moreno, N. Blagorodnova, F. Anders +4
Mass transfer between stars in binary systems profoundly impacts their evolution, yet many aspects of this process (especially the stability, mass loss, and eventual fate of such s…
