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…
Reply to a comment on `Understanding the gamma-ray emission from the globular cluster 47 Tuc: evidence for dark matter?'
Anthony M. Brown, Thomas Lacroix, Sheridan Lloyd +2
Analysing 9 years of Fermi-LAT observations, we recently studied the spectral properties of the prominent globular cluster 47 Tuc (Brown et al. 2018). In particular, we investigate…
The glow of annihilating dark matter in Omega Centauri
Anthony M. Brown, Richard Massey, Thomas Lacroix +3
Dark matter (DM) is the most abundant material in the Universe, but has so far been detected only via its gravitational effects. Several theories suggest that pairs of DM particles…
Looking for ultralight dark matter near supermassive black holes
Nitsan Bar, Kfir Blum, Thomas Lacroix +1
Measurements of the dynamical environment of supermassive black holes (SMBHs) are becoming abundant and precise. We use such measurements to look for ultralight dark matter (ULDM),…
