Substructures in cold dark matter haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We analyse the properties of substructures within dark matter halos (subhalos) using a set of high-resolution numerical simulations of the formation of structure in a Lambda-CDM Universe. Our simulation set includes 11 high-resolution simulations of massive clusters as well as a region of mean density, allowing us to study the spatial and mass ...

Resolving XENON excess with decaying cold dark matter
European Physical Journal C: Particles and Fields, 2021 We propose a decaying cold dark matter model to explain the excess of electron recoil observed at the XENON1T experiment. In this scenario, the daughter dark matter from the parent dark matter decay easily obtains velocity large enough to saturate the ...

Dark Energy and Dark Matter [PDF]
, 2003 It is a puzzle why the densities of dark matter and dark energy are nearly equal today when they scale so differently during the expansion of the universe. This conundrum may be solved if there is a coupling between the two dark sectors. In this paper we

Dark matter candidate from torsion
Physics 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 ...

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 ...

Axinos as Cold Dark Matter [PDF]
AIP Conference Proceedings, 2006 The connection of Dark Matter to our particle physics model is still one of the open cosmological questions. In these proceedings I will argue that axinos can be successful Cold Dark Matter candidates in models with Supersymmetry and the Peccei-Quinn solution of the strong CP problem.

Gravitational Lensing as a Probe of Cold Dark Matter Subhalos
Advances in Astronomy, 2010 In the cold dark matter scenario, dark matter halos are assembled hierarchically from smaller subunits. Some of these subunits are disrupted during the merging process, whereas others survive temporarily in the form of subhalos.
