Halo concentrations in the standard Λ cold dark matter cosmology

F Prada, AA Klypin, AJ Cuesta… - Monthly Notices of …, 2012 - academic.oup.com
We study the concentration of dark matter haloes and its evolution in N-body simulations of
the standard Λ cold dark matter (ΛCDM) cosmology. The results presented in this paper are …

A lower bound on the mass of dark matter particles

A Boyarsky, O Ruchayskiy… - Journal of Cosmology …, 2009 - iopscience.iop.org
We discuss the bounds on the mass of Dark Matter (DM) particles, coming from the analysis
of DM phase-space distribution in dwarf spheroidal galaxies (dSphs). After reviewing the …

Erasing dark matter cusps in cosmological galactic halos with baryons

E Romano-Díaz, I Shlosman, Y Hoffman… - The Astrophysical …, 2008 - iopscience.iop.org

halos. Numerical models with and without baryons (baryons+ DM, hereafter BDM model …

Full calculation of clumpiness boost factors for antimatter cosmic rays in the light of CDM N-body simulation results-Abandoning hope in clumpiness enhancement?

J Lavalle, Q Yuan, D Maurin, XJ Bi - Astronomy & Astrophysics, 2008 - aanda.org
Context. Anti-proton and positron Galactic cosmic ray spectra are among the key targets for
indirect detection of dark matter. The boost factors, corresponding to an enhancement of the …

The dark matter annihilation boost from low-temperature reheating

AL Erickcek - Physical Review D, 2015 - APS
The evolution of the Universe between inflation and the onset of big bang nucleosynthesis is
difficult to probe and largely unconstrained. This ignorance profoundly limits our …

Dissecting galaxy formation. I. Comparison between pure dark matter and baryonic models

E Romano-Diaz, I Shlosman, C Heller… - The Astrophysical …, 2009 - iopscience.iop.org
We compare assembly of dark matter (DM) halos with and without baryons from identical
initial conditions, within the context of cosmological evolution in the ΛCDM WMAP3 Universe …

What makes the family of barred disc galaxies so rich: dam** stellar bars in spinning haloes

A Collier, I Shlosman, C Heller - Monthly Notices of the Royal …, 2018 - academic.oup.com
We model and analyse the secular evolution of stellar bars in spinning dark matter (DM)
haloes with the cosmological spin λ∼ 0–0.09. Using high-resolution stellar and DM …

Model-independent analysis of dark matter points to a particle mass at the keV scale

HJ De Vega, NG Sanchez - Monthly Notices of the Royal …, 2010 - academic.oup.com
We present a model-independent analysis of dark matter (DM) decoupling both
ultrarelativistically (UR) and non-relativistically (NR) based on the DM phase-space density …

Genetically modified haloes: towards controlled experiments in ΛCDM galaxy formation

N Roth, A Pontzen, HV Peiris - Monthly Notices of the Royal …, 2016 - academic.oup.com
We propose a method to generate 'genetically modified'(GM) initial conditions for high-
resolution simulations of galaxy formation in a cosmological context. Building on the …

Constraints on dark matter particles from theory, galaxy observations, and -body simulations

D Boyanovsky, HJ de Vega, NG Sánchez - Physical Review D—Particles …, 2008 - APS
Mass bounds on dark matter (DM) candidates are obtained for particles that decouple in or
out of equilibrium while ultrarelativistic with arbitrary isotropic and homogeneous distribution …
