Very-High-Energy Gamma-Ray Observations as a Probe to the Nature of Dark Matter and Prospects for MACE

Galaxies
Searching for very-high-energy photons arising from dark matter interactions in selected astrophysical environments is a promising strategy to probe the existence and particle nature of dark matter.

The Globular Clusters of Dwarf Spheroidal Galaxies

The Astrophysical Journal, 1998
The possibility that the Sagittarius dwarf spheroidal might have formed as a Searle-Zinn fragment in the outer halo of the Galaxy is discussed. Arguments in favor of this hypothesis are: (1) The luminosity distribution of globular clusters in both Sagittarius and in the outer halo (Rgc > 80 kpc), appear to be bimodal with peaks near MV ~ -5 and MV ~

The Structure and Formation Histories of Low-mass Quiescent Galaxies in the A2744 Cluster Environment

The Astrophysical Journal
Low-mass quiescent galaxies are thought to predominantly reside in overdense regions, as environmental effects are often invoked to explain their shutdown of star formation. These longer-timescale quenching mechanisms—such as interactions with hot gas in

Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies

European Physical Journal C: Particles and Fields
In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $$\Lambda \textrm{CDM}$$ Λ CDM cosmological model and the observed dark ...
