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…
Intermediate mass black holes and dark matter at the Galactic center
Thomas Lacroix, Joseph Silk
Could there be a large population of intermediate-mass black holes (IMBHs) formed in the early universe? Whether primordial or formed in Population III, these are likely to be very…
Dynamical constraints on a dark matter spike at the Galactic Centre from stellar orbits
Thomas Lacroix
In this work I use astrometric and spectroscopic data on the S2 star at the Galactic Centre (GC) up to 2016 to derive specific constraints on the size of a dark matter (DM) spike a…
Unique probe of dark matter in the core of M87 with the Event Horizon Telescope
Thomas Lacroix, Mansour Karami, Avery E. Broderick +2
We demonstrate the unprecedented capabilities of the Event Horizon Telescope (EHT) to image the innermost dark matter profile in the vicinity of the supermassive black hole at the…
Ruling out thermal dark matter with a black hole induced spiky profile in the M87 galaxy
Thomas Lacroix, Celine Boehm, Joseph Silk
Using the spectral energy distribution of M87, a nearby radio galaxy in the Virgo cluster, and assuming a supermassive black hole induced spike in the dark matter halo profile, we…
Constraining the distribution of dark matter at the Galactic centre using the high-resolution Event Horizon Telescope
Thomas Lacroix, Joseph Silk
We investigate constraints on the distribution of dark matter in the neighbourhood of the Galactic centre that may eventually be attained with the high-resolution Event Horizon Tel…
