Warm Dark Matter in Simulations [PDF]
Universe, 2022 In recent years, warm dark matter models have been studied as a viable alternative to the cold dark matter models. The warm dark matter particle properties are expected to imprint distinct signatures on the structure formation at both large and small ...

Indistinguishability of warm dark matter, modified gravity, and coupled cold dark matter [PDF]
Physical Review D, 2013 The current accelerated expansion of our universe could be due to an unknown energy component with negative pressure (dark energy) or a modification to general relativity (modified gravity).

Warm dark matter from a gravitational freeze-in in extra dimensions [PDF]
Journal of High Energy Physics, 2023 We study the freeze-in of gravitationally interacting dark matter in extra dimensions. Focusing on a minimal dark matter candidate that only interacts with the SM via gravity in a five-dimensional model we find that a large range of dark matter and ...

Typical density profile for warm dark matter haloes [PDF]
, 2012 Using the model for (bottom-up) hierarchical halo growth recently developed by Salvador-Sol\'e et al. (2012), we derive the typical spherically averaged density profile for haloes with several relevant masses in the concordant warm dark matter (\Lambda ...

Small-Scale Cosmology “Crisis” and Self-Interacting Right-Handed Neutrino Warm Dark Matter [PDF]
EPJ Web of Conferences, 2018 In the lecture, I first review the basic problems of the ΔCDM model at small (galactic) scales, also known as “small-scale Cosmology crisis”, namely discrepancies between theoretical simulations and observations.

Can We Constrain Warm Dark Matter Masses with Individual Galaxies? [PDF]
The Astrophysical JournalWe study the impact of warm dark matter (WDM) mass on the internal properties of individual galaxies using a large suite of 1024 state-of-the-art cosmological hydrodynamic simulations from the DREAMS project.

Warm Dark Matter from Higher-Dimensional Gauge Theories
Universe, 2021 Warm dark matter particles with masses in the keV range have been linked with the large group representations in gauge theories through a high number of species at decoupling.

Primordial black-hole dark matter via warm natural inflation
Physics Letters B, 2022 We report on a study of the natural warm inflationary paradigm (WNI). We show two important new results arise in this model. One is that the observational constraints on the primordial power spectrum from the cosmic microwave background (CMB) can be ...

A model for mixed warm and hot right-handed neutrino dark matter
Journal of High Energy Physics, 2021 We discuss a model where a mixed warm and hot keV neutrino dark matter rises naturally. We arrange active and sterile neutrinos in the same SU(3) L multiplet, with the lightest sterile neutrino being dark matter.

Dark matter in astrophysics/cosmology
SciPost Physics Lecture Notes, 2022 These lecture notes aim to provide an introduction to dark matter from the perspective of astrophysics/cosmology. We start with a rapid overview of cosmology, including the evolution of the Universe, its thermal history and structure formation.
