Dark matter local density determination: recent observations and future prospects

PF de Salas, A Widmark - Reports on Progress in Physics, 2021 - iopscience.iop.org
This report summarises progress made in estimating the local density of dark matter (ρ
DM,⊙), a quantity that is especially important for dark matter direct detection experiments …

Symmetry of cosmological observables, a mirror world dark sector, and the Hubble constant

FY Cyr-Racine, F Ge, L Knox - Physical Review Letters, 2022 - APS
We find that a uniform scaling of the gravitational free-fall rates and photon-electron
scattering rate leaves most dimensionless cosmological observables nearly invariant. This …

The ALMA-ALPAKA survey-II. Evolution of turbulence in galaxy disks across cosmic time: Difference between cold and warm gas

F Rizzo, C Bacchini, M Kohandel, L Di Mascolo… - Astronomy & …, 2024 - aanda.org
The gas in the interstellar medium (ISM) of galaxies is supersonically turbulent.
Measurements of turbulence typically rely on cold gas emission lines for low-z galaxies and …

Using Gaia DR2 to constrain local dark matter density and thin dark disk

J Buch, SCJ Leung, JJ Fan - Journal of Cosmology and …, 2019 - iopscience.iop.org
We use stellar kinematics from the latest Gaia data release (DR2) to measure the local dark
matter (DM) density ρ DM in a heliocentric cylinder of radius R= 150 pc and half-height z …

Precision cosmological constraints on atomic dark matter

S Bansal, J Barron, D Curtin, Y Tsai - Journal of High Energy Physics, 2023 - Springer
A bstract Atomic dark matter is a simple but highly theoretically motivated possibility for an
interacting dark sector that could constitute some or all of dark matter. We perform a …

Weighing the Galactic disk using phase-space spirals-II. Most stringent constraints on a thin dark disk using Gaia EDR3

A Widmark, CFP Laporte, PF de Salas… - Astronomy & …, 2021 - aanda.org
Using the method that was developed in the first paper of this series, we measured the
vertical gravitational potential of the Galactic disk from the time-varying structure of the …

Constraining a Thin Dark Matter Disk with

K Schutz, T Lin, BR Safdi, CL Wu - Physical review letters, 2018 - APS
If a component of the dark matter has dissipative interactions, it could collapse to form a thin
dark disk in our Galaxy that is coplanar with the baryonic disk. It has been suggested that …

Direct detection of mirror matter in Twin Higgs models

Z Chacko, D Curtin, M Geller, Y Tsai - Journal of High Energy Physics, 2021 - Springer
A bstract We explore the possibility of discovering the mirror baryons and electrons of the
Mirror Twin Higgs model in direct detection experiments, in a scenario in which these …

The volumetric star formation law in the Milky Way

C Bacchini, F Fraternali, G Pezzulli, A Marasco… - Astronomy & …, 2019 - aanda.org
Several open questions on galaxy formation and evolution have their roots in the lack of a
universal star formation law that could univocally link the gas properties, such as its density …

Upgoing ANITA events as evidence of the CPT symmetric universe

LA Anchordoqui, V Barger, JG Learned… - arxiv preprint arxiv …, 2018 - arxiv.org
We explain the two upgoing ultra-high energy shower events observed by ANITA as arising
from the decay in the Earth's interior of the quasi-stable dark matter candidate in the CPT …
