The impact of free-streaming on dwarf galaxy counts in low-density regions
Tamar Meshveliani, Mark R. Lovell, Robert A. Crain +1
We study the statistics of dwarf galaxy populations as a function of environment in the cold dark matter (CDM) and warm dark matter (WDM) cosmogonies, using hydrodynamical simulati…
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…
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…
High and low Sérsic index bulges in Milky Way- and M31-like galaxies: origin and connection to the bar with TNG50
Ignacio D. Gargiulo, Antonela Monachesi, Facundo A. Gómez +8
We study bulge formation in MW/M31-like galaxies in a -cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose we use TNG50, a s…
The spatial distribution of Milky Way satellites, gaps in streams and the nature of dark matter
Mark R. Lovell, Marius Cautun, Carlos S. Frenk +2
The spatial distribution of Milky Way (MW) subhaloes provides an important set of observables for testing cosmological models. These include the radial distribution of luminous sat…
The Onset of Gravothermal Core Collapse in Velocity Dependent Self-Interacting Dark Matter Subhaloes
Hannah C. Turner, Mark R. Lovell, Jesús Zavala +1
It has been proposed that gravothermal collapse due to dark matter self-interactions (i.e. self-interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (…
Local Group star formation in warm and self-interacting dark matter cosmologies
Mark R. Lovell, Wojciech Hellwing, Aaron Ludlow +5
The nature of the dark matter can affect the collapse time of dark matter haloes, and can therefore be imprinted in observables such as the stellar population ages and star formati…
Baryonic clues to the puzzling diversity of dwarf galaxy rotation curves
Isabel M. E. Santos-Santos, Julio F. Navarro, Andrew Robertson +7
We use a compilation of disc galaxy rotation curves to assess the role of the luminous component ("baryons") in the rotation curve diversity problem. As in earlier work, we find th…
The diverse dark matter density at sub-kiloparsec scales in Milky Way satellites:implications for the nature of dark matter
Jesús Zavala, Mark R. Lovell, Mark Vogelsberger +1
Milky Way (MW) satellites reside within dark matter (DM) subhalos with a broad distribution of circular velocity profiles. This diversity is enhanced with the inclusion of ultra-fa…
ETHOS - an effective theory of structure formation: formation of the first haloes and their stars
Mark R. Lovell, Jesús Zavala, Mark Vogelsberger
A cutoff in the linear matter power spectrum at dwarf galaxy scales has been shown to affect the abundance, formation mechanism and age of dwarf haloes and their galaxies at high a…
The IllustrisTNG Simulations: Public Data Release
Dylan Nelson, Volker Springel, Annalisa Pillepich +11
We present the full public release of all data from the TNG50, TNG100 and TNG300 simulations of the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gra…
The fraction of dark matter within galaxies from the IllustrisTNG simulations
Mark R. Lovell, Annalisa Pillepich, Shy Genel +9
We use the IllustrisTNG (TNG) cosmological simulations to provide theoretical expectations for the dark matter mass fractions (DMFs) and circular velocity profiles of galaxies. TNG…
The galaxy population in cold and warm dark matter cosmologies
Lan Wang, Violeta Gonzalez-Perez, Lizhi Xie +7
We use a pair of high resolution N-body simulations implementing two dark matter models, namely the standard cold dark matter (CDM) cosmogony and a warm dark matter (WDM) alternati…
Properties of Local Group galaxies in hydrodynamical simulations of sterile neutrino dark matter cosmologies
Mark R. Lovell, Sownak Bose, Alexey Boyarsky +10
We study galaxy formation in sterile neutrino dark matter models that differ signifi- cantly from both cold and from `warm thermal relic' models. We use the EAGLE code to carry out…
Addressing the too big to fail problem with baryon physics and sterile neutrino dark matter
Mark R. Lovell, Violeta Gonzalez-Perez, Sownak Bose +4
N-body dark matter simulations of structure formation in the CDM model predict a population of subhalos within Galactic halos that have higher central densities than inferred fo…
Mass assembly history and infall time of the Fornax dwarf spheroidal galaxy
Mei-Yu Wang, Louis E. Strigari, Mark R. Lovell +2
We use cosmological simulations to identify dark matter subhalo host candidates of the Fornax dwarf spheroidal galaxy using the stellar kinematic properties of Fornax. We consider…
Simulated Milky Way analogues: implications for dark matter indirect searches
F. Calore, N. Bozorgnia, M. Lovell +7
We study high-resolution hydrodynamic simulations of Milky Way type galaxies obtained within the "Evolution and Assembly of GaLaxies and their Environments" (EAGLE) project, and id…
