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 ...

Self-interacting Dark Matter Interpretation of Crater II

The Astrophysical Journal Letters
The satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold dark matter.
