Halo modelling in chameleon theories [PDF]
, 2014 We analyse modelling techniques for the large-scale structure formed in scalar-tensor theories of constant Brans-Dicke parameter which match the concordance model background expansion history and produce a chameleon suppression of the gravitational ...

Wormhole in the Milky Way galaxy with global monopole charge
European Physical Journal C: Particles and Fields, 2022 Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole.

Figure Rotation of IllustrisTNG Halos
The Astrophysical Journal, 2023 We use the TNG50 and TNG50 dark matter (DM)-only simulations from the IllustrisTNG simulation suite to conduct an updated survey of halo figure rotation in the presence of baryons.

Dark matter annihilation in the Milky Way halo [PDF]
Journal of Physics: Conference Series, 2008 To constrain the particle properties of dark matter using their annihilation products, robust predictions of the annihilation rates are critical. Since the annihilation rate scales as the dark matter density squared, a precise knowledge of the distribution of dark matter is required. Given the popular galactic center contains large uncertainties in the

Infall of Substructures onto a Milky Way-like Dark Halo [PDF]
, 2007 We analyse the dynamical properties of substructures in a high-resolution dark matter simulation of the formation of a Milky Way-like halo in a CDM cosmology.

Imprints of flavor anomalies on neutrino oscillations through dark matter halo
Nuclear Physics B, 2023 In this work we study the impact of new physics, stimulated by flavor anomalies, on neutrino oscillations through dense dark matter halo. Inspired by a model where a Majorana dark matter fermion and two new scalar fields contribute to b→sμ+μ− transition ...

Endothermic self-interacting dark matter in Milky Way-like dark matter haloes
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Self-interacting dark matter (SIDM) offers the potential to mitigate some of the discrepancies between simulated cold dark matter (CDM) and observed galactic properties. We introduce a physically motivated SIDM model to understand the effects of self interactions on the properties of Milky Way and dwarf galaxy sized haloes. This
