Linking X-ray emission to galaxy populations in GAMA groups

Selene Levis, Hernán Muriel, Valeria Coenda +3

We study how the presence of a detectable hot intragroup medium affects galaxy colour and star-formation properties, and how these trends depend on dynamical stage within the group…

Two-Stage Machine Learning Strategy for Scalar and Vector Leptoquark Discrimination at the LHC

Ernesto Arganda, Martín de los Rios, Andres D. Perez +2

We present a machine learning framework for the characterization of leptoquark (LQ) signals at the Large Hadron Collider, focusing on the discrimination between scalar (SLQ) and ve…

Dark Matter profiles of "in silico" galaxies: deep learning inference

Martín de los Rios, Serafina Di Gioia, Fabio Iocco +1

Machine learning has the potential to improve the reconstruction of the dark matter profile of galaxies with respect to traditional methods, like rotation curves. We demonstrate on…

Shedding Light on Dark Matter at the LHC with Machine Learning

Ernesto Arganda, Martín de los Rios, Andres D. Perez +3

We investigate a WIMP dark matter (DM) candidate in the form of a singlino-dominated lightest supersymmetric particle (LSP) within the -symmetric Next-to-Minimal Supersymmetri…

Rotary Masked Autoencoders are Versatile Learners

Uros Zivanovic, Serafina Di Gioia, Andre Scaffidi +3

Applying Transformers to irregular time-series typically requires specializations to their baseline architecture, which can result in additional computational overhead and increase…

Galaxy evolution in groups: Transition galaxies in the IllustrisTNG simulations

Selene Levis, Valeria Coenda, Hernán Muriel +4

The evolution of galaxies is significantly influenced by the environments they inhabit. While high-density regions, such as clusters of galaxies have been widely studied, the dynam…

Reconstructing orbits of galaxies in extreme regions (ROGER). IV. Unveiling galaxy evolution patterns in OmegaWINGS clusters

Hernán Muriel, David Pérez-Millán, Martín de los Rios +6

Clusters of galaxies have proven to be efficient systems in modifying various properties of galaxies, such as star formation or morphology. However, projection effects impose serio…

Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC

Ernesto Arganda, Marcela Carena, Martín de los Rios +4

The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning…

Bayesian technique to combine independently-trained Machine-Learning models applied to direct dark matter detection

David Cerdeno, Martin de los Rios, Andres D. Perez

We carry out a Bayesian analysis of dark matter (DM) direct detection data to determine particle model parameters using the Truncated Marginal Neural Ratio Estimation (TMNRE) machi…

Measuring the Sterile Neutrino Mass in Spallation Source and Direct Detection Experiments

David Alonso-González, Dorian W. P. Amaral, Adriana Bariego-Quintana +2

We explore the complementarity of direct detection (DD) and spallation source (SS) experiments for the study of sterile neutrino physics. We focus on the sterile baryonic neutrino…

Reconstructing Orbits of Galaxies in Extreme Regions (ROGER) III: galaxy evolution patterns in projected phase space around massive X-ray clusters

Hector J. Martinez, Valeria Coenda, Hernan Muriel +2

We use the ROGER code by de los Rios et al. to classify galaxies around a sample of X-ray clusters into five classes according to their positions in the projected phase space diagr…
