Multi-TeV dark matter density in the inner Milky Way halo: spectral and dynamical constraints

Jaume Zuriaga-Puig, Viviana Gammaldi, Daniele Gaggero +2

We develop a comprehensive study of the gamma-ray flux observed by H.E.S.S. in 5 regions of the Galactic Center (GC). Motivated by previous works on a possible Dark Matter (DM) exp…

Analytical insight into dark matter subhalo boost factors for Sommerfeld-enhanced - and -wave -ray signals

Gaétan Facchinetti, Martin Stref, Thomas Lacroix +4

As searches for thermal and self-annihilating dark matter (DM) intensify, it becomes crucial to include as many relevant physical processes and ingredients as possible to refine si…

Classification of gamma-ray targets for velocity-dependent and subhalo-boosted dark-matter annihilation

Thomas Lacroix, Gaétan Facchinetti, Judit Pérez-Romero +4

Gamma-ray observations have long been used to constrain the properties of dark matter (DM), with a strong focus on weakly interacting massive particles annihilating through velocit…

In-depth analysis of the clustering of dark matter particles around primordial black holes I: density profiles

Mathieu Boudaud, Thomas Lacroix, Martin Stref +2

Primordial black holes may have been produced in the early stages of the thermal history of the Universe after cosmic inflation. If so, dark matter in the form of elementary partic…

Towards a more rigorous treatment of uncertainties on the velocity distribution of dark matter particles for capture in stars

José Lopes, Thomas Lacroix, Ilídio Lopes

Dark matter (DM) capture in stars offers a rich phenomenology that makes it possible to probe a wide variety of particle DM scenarios in diverse astrophysical environments. In spit…

Predicting the dark matter velocity distribution in galactic structures: tests against hydrodynamic cosmological simulations

Thomas Lacroix, Arturo Núñez-Castiñeyra, Martin Stref +2

Reducing theoretical uncertainties in Galactic dark matter (DM) searches is an important challenge as several experiments are now delving into the parameter space relevant to popul…
