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.

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

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

Constraints on interacting dark energy models through cosmic chronometers and Gaussian process
European 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]
, 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.

The mass–concentration–redshift relation of cold and warm dark matter haloes [PDF]
, 2016 We use a suite of cosmological simulations to study the mass–concentration–redshift relation, c(M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter (CDM) models, and additional runs with truncated power spectra, consistent ...

Crater 2: An Extremely Cold Dark Matter Halo [PDF]
, 2016 We present results from MMT/Hectochelle spectroscopy of 390 red giant candidate stars along the line of sight to the recently discovered Galactic satellite Crater 2. Modeling the joint distribution of stellar positions, velocities, and metallicities as a
