Axion dark matter searches from the standard halo over the tidal stream to the big flow
Journal of High Energy PhysicsThe sensitivity of axion dark matter searches depends on the signal window that results from the velocity dispersion of axion dark matter. Since the ratio of signal windows is about 6500 between the standard halo and the big flow axion dark matter, each ...

Particle motion and QPOs around Euler-Heisenberg black hole immersed in cold dark matter halo
Nuclear Physics BWe explore the motion of particles in the vicinity of an Euler-Heisenberg black hole immersed in a cold dark matter halo, focusing on how the black hole parameters influence particle dynamics. This black hole solution is characterized by five parameters,

Using frequency maps to explore the distribution function of the Milky Way stellar halo
EPJ Web of Conferences, 2012 Resolved surveys of the Milky Way's stellar halo can obtain all 6 phase space coordinates of tens of thousands of individual stars, making it possible to compute their 3-dimensional orbits.

Modeling the Galaxy Distribution in Clusters using Halo Cores
The Open Journal of Astrophysics, 2023 The galaxy distribution in dark matter-dominated halos is expected to approximately trace the details of the underlying dark matter substructure. In this paper we introduce halo "core-tracking" as a way to efficiently follow the small-scale substructure ...

Halo-Independent Comparison of Direct Dark Matter Detection Data
Advances in High Energy Physics, 2014 We review the halo-independent formalism that allows comparing data from different direct dark matter detection experiments without making assumptions on the properties of the dark matter halo.

The halo model for cosmology: a pedagogical review
The Open Journal of Astrophysics, 2023 We present a pedagogical review of the halo model, a flexible framework that can describe the distribution of matter and its tracers on non-linear scales for both conventional and exotic cosmological models.

Universal scaling laws and density slopes for dark matter haloes
Scientific Reports, 2023 Smalls scale challenges suggest some missing pieces in our current understanding of dark matter. A cascade theory for dark matter is proposed to provide extra insights, similar to the cascade phenomenon in hydrodynamic turbulence.
