Dark matter–radiation interactions: the impact on dark matter haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Interactions between dark matter (DM) and radiation (photons or neutrinos) in the early Universe suppress density fluctuations on small mass scales. Here we perform a thorough analysis of structure formation in the fully non-linear regime using N-body simulations for models with DM-radiation interactions and compare the results to a traditional ...

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.

Constraining primordial black holes as dark matter using AMS-02 data
European Physical Journal C: Particles and FieldsPrimordial black holes (PBHs) are the plausible candidates for the cosmological dark matter. Theoretically, PBHs with masses $$M_{\textrm{PBH}}$$ M PBH in the range of $$4\times 10^{14}\sim 10^{17}\,\textrm{g}$$ 4 × 10 14 ∼ 10 17 g can emit sub-GeV ...

VIS - Nordic Journal for Artistic ResearchDarkness Matters displays historic lightscapes, specifically at night, from petroglyphs to James Webb Telescope images. The exposition constructs a sort of cabinet of curiosities and wants to take the visitor on a private journey to a virtual exhibition space to re-embrace the endeavors under and around the nocturnal vault, an underrepresented micro ...

Physics Letters B, 2003 Velocity-dependent interactions in a fundamental-string dominated universe lead quite naturally, with reasonable assumptions on initial conditions, to an accelerating expanding universe without assuming the existence of a cosmological constant. This result also holds generically for a universe dominated by moving extremal black holes, owing to a ...

Dark Matter “Collider” from Inelastic Boosted Dark Matter [PDF]
Physical Review Letters, 2017 We propose a novel dark matter (DM) detection strategy for the models with non-minimal dark sector. The main ingredients in the underlying DM scenario are a boosted DM particle and a heavier dark sector state. The relativistic DM impinged on target material scatters off inelastically to the heavier state which subsequently decays into DM along with ...

Theoretical strategies for comparing dark matter searches [PDF]
, 2022 The thesis discusses two semplified models describing the dark matter particle and the mediator of its interaction with the standard model, with a critical discussion of the validity of the effective theory in these two case studies.
