Brief History of Ultra-light Scalar Dark Matter Models [PDF]
EPJ Web of Conferences, 2018 This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion. In this model ultra-light scalar dark matter particles with mass m = O(10-22)eV condense

Warm Little Inflaton Becomes Cold Dark Matter [PDF]
Physical Review Letters, 2019 We present a model where the inflaton can naturally account for all the dark matter in the Universe within the warm inflation paradigm. In particular, we show that the symmetries and particle content of the warm little inflaton scenario (i) avoid large ...

Cold dark matter: Controversies on small scales. [PDF]
Proc Natl Acad Sci U S A, 2015 The cold dark matter (CDM) cosmological model has been remarkably successful in explaining cosmic structure over an enormous span of redshift, but it has faced persistent challenges from observations that probe the innermost regions of dark matter halos ...

Cold keV dark matter from decays and scatterings [PDF]
, 2017 We explore ways of creating cold keV-scale dark matter by means of decays and scatterings. The main observation is that certain thermal freeze-in processes can lead to a cold dark matter distribution in regions with small available phase space.

Observational evidence for self-interacting cold dark matter [PDF]
Physical Review Letters, 2000 Cosmological models with cold dark matter composed of weakly interacting particles predict overly dense cores in the centers of galaxies and clusters and an overly large number of halos within the Local Group compared to actual observations.

Dark matter effect on the weak deflection angle by black holes at the center of Milky Way and M87 galaxies [PDF]
European Physical Journal C: Particles and Fields, 2022 In this paper, we investigated the effect of dark matter on the weak deflection angle by black holes at the galactic center. We consider three known dark matter density profiles such as the Cold Dark Matter, Scalar Field Dark Matter, and the Universal ...

How Cold is Cold Dark Matter? [PDF]
, 2014 If cold dark matter consists of particles, these must be non-interacting and non-relativistic by definition. In most cold dark matter models however, dark matter particles inherit a non-vanishing velocity dispersion from interactions in the early ...

NIHAO IX: the role of gas inflows and outflows in driving the contraction and expansion of cold dark matter haloes [PDF]
, 2016 We use similar to 100 cosmological galaxy formation 'zoom-in' simulations using the smoothed particle hydrodynamics code GASOLINE to study the effect of baryonic processes on the mass profiles of cold dark matter haloes.

Warm dark matter does not do better than cold dark matter in solving small-scale inconsistencies [PDF]
, 2014 Over the last decade, warm dark matter (WDM) has been repeatedly proposed as an alternative scenario to the standard cold dark matter (CDM) one, potentially resolving several disagreements between the CDM model and observations on small scales.

IWDM: the fate of an interacting non-cold dark matter — vacuum scenario [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 In most cosmological models, the equation of state of the dark matter is assumed to be zero, which means that the dark matter is pressure-less or cold. While this hypothesis is based on the abundance of cold dark matter in the universe, however, there is
