Neutrino Constraints on the Dark Matter Total Annihilation Cross Section [PDF]
, 2007 In the indirect detection of dark matter through its annihilation products, the signals depend on the square of the dark matter density, making precise knowledge of the distribution of dark matter in the Universe critical for robust predictions.

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.

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 ...

What the Milky Way's Dwarfs tell us about the Galactic Center extended excess [PDF]
, 2017 The Milky Way's Galactic Center harbors a gamma-ray excess that is a candidate signal of annihilating dark matter. Dwarf galaxies remain predominantly dark in their expected commensurate emission.

A mass-dependent density profile for dark matter haloes including the influence of galaxy formation [PDF]
, 2014 We introduce a mass-dependent density profile to describe the distribution of dark matter within galaxies, which takes into account the stellar-to-halo mass dependence of the response of dark matter to baryonic processes.

Stream Fanning and Bifurcations: Observable Signatures of Resonances in Stellar Stream Morphology
The Astrophysical Journal, 2023 Recent observations have revealed a trove of unexpected morphological features in many of the Milky Way’s stellar streams. Explanations for such features include time-dependent deformations of the Galactic gravitational potential, local disruptions ...

Low-metallicity stellar halo populations as tracers of dark matter haloes [PDF]
, 2014 We analyse the density profiles of the stellar halo populations in eight Milky-Way mass galaxies, simulated within the $\Lambda$-Cold Dark Matter scenario.
