Fast emulation of cosmological density fields based on dimensionality reduction and supervised machine-learning
Miguel Conceição, Alberto Krone-Martins, Antonio da Silva +1
N-body simulations are the most powerful method to study the non-linear evolution of large-scale structure. However, they require large amounts of computational resources, making u…
Sensitivity of strong lensing observations to dark matter substructure: a case study with Euclid
Conor M. O'Riordan, Giulia Despali, Simona Vegetti +2
We introduce a machine learning method for estimating the sensitivity of strong lens observations to dark matter subhaloes in the lens. Our training data include elliptical power-l…
LCDM halo substructure properties revealed with high resolution and large volume cosmological simulations
Ángeles Moliné, Miguel A. Sánchez-Conde, Alejandra Aguirre-Santaella +8
We investigate the structural properties, distribution and abundance of LCDM dark matter subhaloes using the Phi-4096 and Uchuu suite of N-body cosmological simulations. Thanks to…
Properties of subhalos in the interacting dark matter scenario
Ángeles Moliné, Jascha A. Schewtschenko, Miguel A. Sánchez-Conde +3
One possible and natural derivation from the collisionless cold dark matter (CDM) standard cosmological framework is the assumption of the existence of interactions between dark ma…
The 21 cm signal and the interplay between dark matter annihilations and astrophysical processes
Laura Lopez-Honorez, Olga Mena, Ángeles Moliné +2
Future dedicated radio interferometers, including HERA and SKA, are very promising tools that aim to study the epoch of reionization and beyond via measurements of the 21 cm signal…
Isotropic extragalactic flux from dark matter annihilations: lessons from interacting dark matter scenarios
Ángeles Moliné, Jascha A. Schewtschenko, Sergio Palomares-Ruiz +2
The extragalactic gamma-ray and neutrino emission may have a contribution from dark matter (DM) annihilations. In the case of discrepancies between observations and standard predic…
Future sensitivity of neutrino telescopes to dark matter annihilations from the cosmic diffuse neutrino signal
Angeles Moline, Alejandro Ibarra, Sergio Palomares-Ruiz
Cosmological observations and cold dark matter N-body simulations indicate that our Universe is populated by numerous halos, where dark matter particles annihilate, potentially pro…
