The DREAMS Project: Disentangling the Impact of Halo-to-halo Variance and Baryonic Feedback on Milky Way Dark Matter Density Profiles

The Astrophysical Journal
In this work, we utilize a new suite of Milky Way–mass halos from the DREAMS Project, simulated with cold dark matter (CDM), to quantify the influence of baryon feedback and intrinsic halo-to-halo variance on dark matter density profiles.

The AIDA-TNG project: Abundance, radial distribution, and clustering properties of halos in alternative dark matter models

Astronomy & Astrophysics
Warm and self-interactive dark matter cosmologies have been proposed as nonbaryonic solutions to the tensions between the Λ cold dark matter model and observations at the kiloparsec scale.

The Clustering of Dark Matter, Haloes & Galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particlesin the Universe. The subjects investigated are conceptually divided into three areas.One line of research, which is made up of Chapters 2 and 3， is to explore ...

The DREAMS Project: Disentangling the Impact of Halo-to-Halo Variance and Baryonic Feedback on Milky Way Dark Matter Speed Distributions

The Astrophysical Journal
Dark matter direct detection experiments require information about the local dark matter speed distribution to produce constraints on dark matter candidates, or infer their properties in the event of a discovery.

Biasing and the distribution of dark matter haloes [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
In hierarchical models of gravitational clustering, virialized haloes are biased tracers of the matter distribution. As discussed by Mo & White (1996), this bias is nonlinear and stochastic. They developed a model which allows one to write down analytic expressions for the mean of the bias relation, in the initial Lagrangian, and the evolved ...

Galactic Dark Matter distribution and its implications for experimental searches [PDF]

, 2019
Dark Matter presents one of the key missing pieces in our understanding of the Universe. On the one hand, there is a substantial amount of independent astronomical and cosmological observations, which provide convincing evidence for its existence through

The Roman View of Strong Gravitational Lenses

The Astrophysical Journal
Galaxy–galaxy strong gravitational lenses can constrain dark matter models and the Lambda cold dark matter cosmological paradigm at subgalactic scales. Currently, there is a dearth of images of these rare systems with high signal-to-noise ratio (SNR) and

The internal structure of Cold Dark Matter Haloes [PDF]

, 2010
Currently favoured cosmological models for structure formation of the Universe assume that a large fraction of the mass of the Universe is 'dark'. The evidence for dark matter comes from observations of its gravitational influence.
