, 2018 The Milky Way is made up of a central bar, a disk with embedded spiral arms, and a dark matter halo. Observational and theoretical constraints for the characteristic parameters of these components will be presented, with emphasis on the constraints from ...

Ursa Major III/UNIONS 1: The Darkest Galaxy Ever Discovered?
The Astrophysical JournalThe recently discovered stellar system Ursa Major III/UNIONS 1 (UMa3/U1) is the faintest known Milky Way satellite to date. With a stellar mass of ${16}_{-5}^{+6}\,{M}_{\odot }$ and a half-light radius of 3 ± 1 pc, it is either the darkest galaxy ever ...

Dark matter spiral arms in Milky Way-like halos
Astronomy & AstrophysicsContext. The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM halos has been explored (e.g. slowing down of the bar due to dynamical friction), the effect of spiral arms on the DM halo distribution has received limited attention ...

What's up in the Milky Way? The orientation of the disc relative to the triaxial halo [PDF]
, 2013 Models of the Sagittarius stream have consistently found that the Milky Way disc is oriented such that its short axis is along the intermediate axis of the triaxial dark matter halo.

The clustering of dark matter, haloes & galaxies [PDF]
, 2008 In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Search for dark matter candidates and large extra dimensions in events with a jet and missing transverse momentum with the ATLAS detector [PDF]
, 2013 A search for new phenomena in events with a high-energy jet and large missing transverse momentum is performed using data from proton-proton collisions at √s=7 TeV with the ATLAS experiment at the Large Hadron Collider.

Dark Matter Halo Tumbling Induced by Torques from Massive Mergers
The Astrophysical JournalDark matter halos exhibit slow tumbling known as “figure rotation.” Figure rotation occurs in roughly 80% of isolated ΛCDM halos and is relatively unaffected by baryonic feedback, making it an attractive and relatively unexplored test for ΛCDM.

Simulations of satellite tidal debris in the Milky Way halo
, 2020 Aims. We study the distribution of the stellar and dark matter debris of the Milky Way satellites. Methods. For the first time we address the question of the tidal disruption of satellites in simulations by utilising simultaneously (a) a realistic set of

Challenges in Binary Pulsar Timing Detection of Dark Matter Subhalos
The Astrophysical Journal LettersRecently, binary pulsar timing has been proposed as a viable probe of dark matter subhalos with masses of ∼10 ^7 M _⊙ in the solar neighborhood.
