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…
Gravothermal collapse of Self-Interacting Dark Matter halos as the Origin of Intermediate Mass Black Holes in Milky Way satellites
Tamar Meshveliani, Jesús Zavala, Mark R. Lovell
Milky Way (MW) satellites exhibit a diverse range of internal kinematics, reflecting in turn a diverse set of subhalo density profiles. These profiles include large cores and dense…
Matching the mass function of Milky Way satellites in competing dark matter models
Mark R. Lovell, Jesús Zavala
Any successful model of dark matter must explain the diversity of observed Milky Way (MW) satellite density profiles, from very dense ultrafaints to large, low density satellites s…
Differentiating small-scale subhalo distributions in CDM and WDM models using persistent homology
Jessi Cisewski-Kehe, Brittany Terese Fasy, Wojciech Hellwing +3
The spatial distribution of galaxies at sufficiently small scales will encode information about the identity of the dark matter. We develop a novel description of the halo distribu…
Could fresh lava be (warm) dark matter?
Mark R. Lovell
Dark matter models can be classified according to their impact on the properties of galaxies, including cold dark matter (CDM), warm dark matter (WDM), self-interacting dark matter…
Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements
Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
The feasibility of constraining DM interactions with high-redshift observations by JWST
Ali Kurmus, Sownak Bose, Mark Lovell +4
Observations of the high redshift universe provide a promising avenue for constraining the nature of the dark matter (DM). This will be even more true with the advent of the James…
