Shadows of black holes with dark matter halo [PDF]
Physical Review D, 2023 We investigate the shadow of an exact black hole solution of Einstein's equations recently proposed by Cardoso et al., to describe a supermassive black hole immersed in a dark matter halo.

Dynamical friction in dark matter superfluids: The evolution of black hole binaries [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 The theory of superfluid dark matter is characterized by self-interacting sub-eV particles that thermalize and condense to form a superfluid core in galaxies. Massive black holes at the center of galaxies, however, modify the dark matter distribution and

Clumps and streams in the local dark matter distribution [PDF]
Nature, 2008 In cold dark matter cosmological models, structures form and grow through the merging of smaller units. Numerical simulations have shown that such merging is incomplete; the inner cores of haloes survive and orbit as ‘subhaloes’ within their hosts.

Astrophysical uncertainties on the local dark matter distribution and direct detection experiments [PDF]
, 2017 The differential event rate in weakly interacting massive particle (WIMP) direct detection experiments depends on the local dark matter density and velocity distribution.

Dark matter distribution in X-ray luminous galaxy clusters with Emergent Gravity [PDF]
, 2016 We present the radial distribution of the dark matter in two massive, X-ray luminous galaxy clusters, Abell~2142 and Abell~2319, and compare it with the quantity predicted as apparent manifestation of the baryonic mass in the context of the "Emergent ...

Baryonic and dark matter distribution in cosmological simulations of spiral galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2014 We study three cosmological hydrodynamical simulations of Milky Way(MW)-sized haloes including a comparison with the dark matter(DM)-only counterparts. We find one of our simulated galaxies with interesting MW-like features.

Baryonic impact on the dark matter distribution in Milky Way-sized galaxies and their satellites [PDF]
, 2015 We study the impact of baryons on the distribution of dark matter in a Milky Way-size halo by comparing a high-resolution, moving-mesh cosmological simulation with its dark matter-only counterpart.

How does dark matter affect compact star properties and high density constraints of strongly interacting matter [PDF]
EPJ Web of Conferences, 2022 We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution inside the star.
