Detecting cold dark-matter candidates [PDF]

open access: yesPhysical Review D, 1986
We consider the use of superheated superconducting colloids as detectors of weakly interacting galactic halo candidate particles (e.g. photinos, massive neutrinos, and scalar neutrinos). These low temperature detectors are sensitive to the deposition of a few hundreds of eV's.

Dark matter candidate from torsion

open access: yesPhysics Letters B, 2022
The stable pseudo-scalar degree of freedom of the quadratic Poincaré Gauge theory of gravity is shown to be a suitable dark matter candidate. We find the parameter space of the theory which can account for all the predicted cold dark matter, and ...

Primordial Black Holes as Dark Matter: Recent Developments [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2020
Although the dark matter is usually assumed to be made up of some form of elementary particle, primordial black holes (PBHs) could also provide some of it.

Gravitational waves from dark matter isocurvature [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2021
The primordial fluctuations on large scales are adiabatic, but on smaller scales this need not be the case. Here we derive the general analytical framework to compute the stochastic gravitational wave background induced by primordial cold dark matter ...

NIHAO IX: the role of gas inflows and outflows in driving the contraction and expansion of cold dark matter haloes [PDF]

open access: yes, 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.

Halo cold dark matter and microlensing [PDF]

open access: yesPhysical Review Letters, 1994
There is good evidence that most of the baryons in the Universe are dark and some evidence that most of the matter in the Universe is nonbaryonic with cold dark matter (cdm) being a promising possibility. We discuss expectations for the abundance of baryons and cdm in the halo of our galaxy and locally.

Constraints on interacting dark energy models through cosmic chronometers and Gaussian process

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper, after reconstructing the redshift evolution of the Hubble function by adopting Gaussian process techniques, we estimate the best-fit parameters for some flat Friedmann cosmological models based on a modified Chaplygin gas interacting with ...

Cold dark matter plus not-so-clumpy dark relics [PDF]

open access: yes, 2017
Various particle physics models suggest that, besides the (nearly) cold dark matter that accounts for current observations, additional but sub-dominant dark relics might exist. These could be warm, hot, or even contribute as dark radiation.

New interactions in the dark sector mediated by dark energy [PDF]

open access: yes, 2008
Cosmological observations have revealed the existence of a dark matter sector, which is commonly assumed to be made up of one particle species only. However, this sector might be more complicated than we currently believe: there might be more than one ...
