[HTML][HTML] Ultra-light dark matter

EGM Ferreira - The Astronomy and Astrophysics Review, 2021 - Springer
Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

Stellar dynamics and dark matter in Local Group dwarf galaxies

G Battaglia, C Nipoti - Nature Astronomy, 2022 - nature.com
When interpreted within the standard framework of Newtonian gravity and dynamics, the
kinematics of stars and gas in dwarf galaxies reveals that most of these systems are …

Einstein rings modulated by wavelike dark matter from anomalies in gravitationally lensed images

A Amruth, T Broadhurst, J Lim, M Oguri, GF Smoot… - Nature …, 2023 - nature.com
Unveiling the true nature of dark matter, which manifests itself only through gravity, is one of
the principal quests in physics. Leading candidates for dark matter are weakly interacting …

Dynamical friction of black holes in ultralight dark matter

R Vicente, V Cardoso - Physical Review D, 2022 - APS
In this work we derive simple closed-form expressions for the dynamical friction acting on
black holes moving through ultralight (scalar field) dark matter, covering both nonrelativistic …

Small-scale structure in vector dark matter

MA Amin, M Jain, R Karur, P Mocz - Journal of Cosmology and …, 2022 - iopscience.iop.org
We investigate the differences in the small-scale structure of vector dark matter (VDM) and
scalar dark matter (SDM) using 3+ 1 dimensional simulations of single/multicomponent …

Strong dark matter self-interactions diversify halo populations within and surrounding the milky way

D Yang, EO Nadler, HB Yu - The Astrophysical Journal, 2023 - iopscience.iop.org
We perform a high-resolution cosmological zoom-in simulation of a Milky Way (MW)–like
system, which includes a realistic Large Magellanic Cloud analog, using a large differential …

The diversity of core–halo structure in the fuzzy dark matter model

HYJ Chan, EGM Ferreira, S May… - Monthly Notices of the …, 2022 - academic.oup.com
In the fuzzy dark matter (FDM) model, gravitationally collapsed objects always consist of a
solitonic core located within a virialized halo. Although various numerical simulations have …

Core-collapse, evaporation, and tidal effects: the life story of a self-interacting dark matter subhalo

ZC Zeng, AHG Peter, X Du, A Benson… - Monthly Notices of …, 2022 - academic.oup.com
Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter
(DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The …

The onset of gravothermal core collapse in velocity-dependent self-interacting dark matter subhaloes

HC Turner, MR Lovell, J Zavala… - Monthly Notices of the …, 2021 - academic.oup.com
It has been proposed that gravothermal collapse due to dark matter self-interactions (ie self-
interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (MW) …

TangoSIDM: tantalizing models of self-interacting dark matter

CA Correa, M Schaller, S Ploeckinger… - Monthly Notices of …, 2022 - academic.oup.com
We introduce the TangoSIDM project, a suite of cosmological simulations of structure
