Exothermic dark matter for XENON1T excess
Journal of High Energy Physics, 2021 Motivated by the recent excess in the electron recoil from XENON1T experiment, we consider the possibility of exothermic dark matter, which is composed of two states with mass splitting.

A closer look at dark matter production in exponential growth scenarios
Journal of High Energy PhysicsWe investigate a recently proposed non-thermal mechanism for dark matter production, in which a small initial dark matter (χ) number density undergoes exponential growth through scatterings with bath particles (ϕ) in the early universe (χϕ → χχ).

A Dense Dark Matter Core of the Subhalo in the Strong Lensing System JVAS B1938+666
The Astrophysical Journal LettersThe nature of dark matter remains unknown, motivating the study of fuzzy/wave dark matter (FDM/ ψ DM) and self-interacting dark matter (SIDM) as alternative frameworks to address small-scale discrepancies in halo profiles inferred from observations. This

The Astrophysical Journal, 2022 Stellar streams from globular clusters (GCs) offer constraints on the nature of dark matter and have been used to explore the dark matter halo structure and substructure of our Galaxy. Detection of GC streams in other galaxies would broaden this endeavor

Dark Matter Signals in the gamma-ray sky
EPJ Web of Conferences, 2014 Detection of gamma rays and cosmic rays from the annihilation or decay of dark matter particles is a promising method for identifying dark matter, understanding its intrinsic properties, and mapping its distribution in the universe.

Distribution of dark matter in the spiral galaxy NGC 3198
The Astrophysical Journal, 1985 Two-component mass models, consisting of an exponential disk and a spherical halo, are constructed to fit a newly determined rotation curve of NGC 3198 that extends to 11 disk scale lengths. The amount of dark matter inside the last point of the rotation curve, at 30 kpc, is at least 4 times larger than the amount of visible matter, with M/L(B)tot = 18

Dark Universe and distribution of matter as quantum imprinting
, 2018 In this paper we want to analyze the Dark Matter problem and the distribution of matter through two different approaches, which are linked by the possibility that the solution of these astronomical puzzles should be sought in the quantum imprinting of ...

Probing multicomponent extension of inert doublet model with a vector dark matter
European Physical Journal C: Particles and Fields, 2019 Although theoretically well-motivated as a minimal consistent dark matter (DM) model, the inert doublet model (IDM) fell short in explaining the existence of DM in the intermediate mass region (100–500 GeV).
