A Broker Integrated Algorithm for Gravitational Wave - Electromagnetic Counterpart Searches in O4a and O4b Runs

Hemanth Bommireddy, Francisco Forster, Isaac McMahon +6

We present an automated framework to search for optical counterparts of LIGO-Virgo-KAGRA (LVK) gravitational wave (GW) superevents using public Zwicky Transient Facility (ZTF) aler…

NICER observations reveal doubled timescales in Ansky's quasi-periodic eruptions (QPEs)

L. Hernández-García, P. Sánchez-Sáez, J. Chakraborty +11

Quasi-periodic eruptions (QPEs) are recurring X-ray bursts originating from the vicinity of supermassive black holes, but their driving mechanisms remain under debate. This study a…

L'explicabilité au service de l'extraction de connaissances : application à des données médicales

Robin Cugny, Emmanuel Doumard, Elodie Escriva +1

The use of machine learning has increased dramatically in the last decade. The lack of transparency is now a limiting factor, which the field of explainability wants to address. Fu…

Testing the consistency between cosmological data: the impact of spatial curvature and the dark energy EoS

Javier E. Gonzalez, Micol Benetti, Rodrigo von Marttens +1

The results of joint analyses of available cosmological data have motivated an important debate about a possible detection of a non-zero spatial curvature. If confirmed, such a res…

A model-independent reconstruction of dark sector interactions

Rodrigo von Marttens, Javier E. Gonzalez, Jailson Alcaniz +2

Relaxing the conventional assumption of a minimal coupling between the dark matter (DM) and dark energy (DE) fields introduces significant changes in the predicted evolution of the…

Gravitational lens time-delay as a probe of a possible time variation of the fine-structure constant

L. R. Colaço, J. E. Gonzalez, R. F. L. Holanda

A new method based on large-scale structure observations is proposed to probe a possible time variation of the fine-structure constant (). Our analyses are based on time-delay o…

On the Stability of the Cauchy Problem of Timoshenko Thermoelastic Systems with Past History: Cattaneo and Fourier Law

Hugo D. Fernandez Sare, Fernando A. Gallego

In this paper, we investigate the decay properties of the thermoelastic Timoshenko system with past history in the whole space where the thermal effects are given by Cattaneo and F…
