Subhaloes in Self-Interacting Galactic Dark Matter Haloes

open access: yes, 2012
We present N-body simulations of a new class of self-interacting dark matter models, which do not violate any astrophysical constraints due to a non-power-law velocity dependence of the transfer cross section which is motivated by a Yukawa-like new gauge

Modelling the Milky Way through adiabatic compression of cold dark matter haloes [PDF]

open access: yesAstronomy & Astrophysics, 2005
We use the adiabatic compression theory to build a physically well - motivated Milky Way mass model in agreement with the observational data. The visible mass of the Galaxy is distributed in a spheroidal bulge and a multi - components disc parametrized by three galactic parameters, the Sun distance to the galactic centre, R_0, the total bulge mass, M_ ...

Empirical Determination of Dark Matter Velocities using Metal-Poor Stars [PDF]

open access: yes, 2017
The Milky Way dark matter halo is formed from the accretion of smaller subhalos. These sub-units also harbor stars---typically old and metal-poor---that are deposited in the Galactic inner regions by disruption events.

Small scale structures in coupled scalar field dark matter

open access: yesPhysics Letters B, 2014
We investigate structure formation for ultra-light scalar field dark matter coupled to quintessence, in particular the cosmon–bolon system. The linear power spectrum is computed by a numerical solution of the coupled field equations.

Bright gamma-ray Galactic Center excess and dark dwarfs: Strong tension for dark matter annihilation despite Milky Way halo profile

open access: yes, 2016
We incorporate Milky Way dark matter halo profile uncertainties, as well as an accounting of diffuse gamma-ray emission uncertainties in dark matter annihilation models for the Galactic Center Extended gamma-ray excess (GCE) detected by the Fermi Gamma ...

Implications for dark matter direct detection in the presence of LIGO-motivated primordial black holes

open access: yesPhysics Letters B, 2020
We discuss formation of dark matter (DM) mini-halos around primordial black holes (PBHs) and its implication on DM direct detection experiments, including axion searches.

Gamma-rays From Warm WIMP Dark Matter Annihilation

open access: yes, 2012
The weakly interacting massive particle (WIMP) often serves as a candidate for the cold dark matter, however when produced non-thermally it could behave like warm dark matter.

One‐Step Microfluidic Manufactured Fucose‐Decorated Sweetosomes Choose the Time and the Road for Their Intracellular Journey to Cancer Treatment

open access: yesAdvanced Healthcare Materials, EarlyView.
Sweetosomes, a new class of fucose‐decorated liposomes, are developed via a one‐step microfluidic process without surface chemistry. This study elucidates their main caveolae‐mediated entry and distinct endosomal trafficking. These nanostructures demonstrate superior endosomal escape, organelle acidity modulation, and prolonged plasma persistence ...

Symphony: Cosmological Zoom-in Simulation Suites over Four Decades of Host Halo Mass

open access: yesThe Astrophysical Journal, 2023
We present Symphony, a compilation of 262 cosmological, cold-dark-matter-only zoom-in simulations spanning four decades of host halo mass, from 10 ^11 –10 ^15 M _⊙ .
