Phase-space mass bound for fermionic dark matter from dwarf spheroidal galaxies

  journal={Monthly Notices of the Royal Astronomical Society},
We reconsider the lower bound on the mass of a fermionic dark matter (DM) candidate resulting from the existence of known small Dwarf Spheroidal galaxies, in the hypothesis that their DM halo is constituted by degenerate fermions, with phase-space density limited by the Pauli exclusion principle. By relaxing the common assumption that the DM halo scale radius is tied to that of the luminous stellar component and by marginalizing on the unknown stellar velocity dispersion anisotropy, we prove…

New constraints on the mass of fermionic dark matter from dwarf spheroidal galaxies

Dwarf spheroidal galaxies are excellent systems to probe the nature of fermionic dark matter due to their high observed dark matter phase-space density. In this work, we review, revise and improve

Phase-Space Bounds on the Mass of Dark Matter in Fermi Degenerate Non-Isothermal Galaxies

The phase-space bounds on the mass of dark matter are mostly derived for isothermal galactic halos. In this paper, we study slight deviations from the isothermal condition. We show that if fermionic

Ultralight Thomas-Fermi dark matter

Author(s): Pal, K; Sales, LV; Wudka, J | Abstract: We investigate the viability of a simple dark matter (DM) model consisting of a single fermion in the context of galactic dynamics. We use a

Ultralight fermionic dark matter

Conventional lore from Tremaine and Gunn excludes fermionic dark matter lighter than a few hundred eV, based on the Pauli exclusion principle. We highlight a simple way of evading this bound with a

Assessment of Dark Matter Models Using Dark Matter Correlations across Dwarf Spheroidal Galaxies

The predicted size of dark matter substructures in kilo-parsec scales is model-dependent. Therefore, if the correlations between dark matter mass densities as a function of the distances between them

I summarize our recent results to use the orbits of globular clusters (GCs) in the Fornax dwarf spheroidal (dSph) galaxy to learn more about dark matter (DM) properties. Our focus is on clarifying

Extreme dark matter tests with extreme mass ratio inspirals

Future space-based laser interferometry experiments such as LISA are expected to detect $\cal O$(100--1000) stellar-mass compact objects (e.g., black holes, neutron stars) falling into massive black

Context. The Λ cold dark matter (ΛCDM) scenario is able to describe the Universe at large scales, but clearly shows some serious difficulties at small scales. The core-cusp question is one of these

I begin by briefly reviewing the evidence for the existence of Dark Matter (DM), emphasizing that {\em many} observations, at length scales between kpc (the size of the smallest galaxies) and Gpc




The distribution of dark matter around galactic or cluster halos has usually been assumed to be approximately isothermal with a non-zero core radius, which is expected to be of the order of the size

A lower bound on the mass of dark matter particles

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 existing approaches,

Cores in Dwarf Galaxies from Fermi Repulsion

We show that Fermi repulsion can lead to cored density profiles in dwarf galaxies for sub-keV fermionic dark matter. We treat the dark matter as a quasi-degenerate self-gravitating Fermi gas and

Dwarf spheroidal galaxies as degenerate gas of free fermions

In this paper we analyze a simple scenario in which Dark Matter (DM) consists of free fermions with mass mf. We assume that on galactic scales these fermions are capable of forming a degenerate Fermi

Halo Cores and Phase-Space Densities: Observational Constraints on Dark Matter Physics and Structure Formation

We explore observed trends in the cores of a wide range of relaxed dark matter-dominated halos (about 7 orders of magnitude in mass) to constrain hypothetical dark matter candidates and scenarios of

Halo Formation in Warm Dark Matter Models

Discrepancies have emerged between the predictions of standard cold dark matter (CDM) theory and observations of clustering on subgalactic scales. Warm dark matter (WDM) is a simple modification of

Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows

Hydrodynamical simulations in a framework assuming the presence of CDM and a cosmological constant are reported in which the inhomogeneous interstellar medium is resolved and the analogues of dwarf galaxies—bulgeless and with shallow central dark-matter profiles—arise naturally in these simulations.

The cores of dwarf galaxy haloes

We use N-body simulations to examine the effects of mass outflows on the density profiles of cold dark matter (CDM) halos surrounding dwarf galaxies. In particular, we investigate the consequences of

The Structure of cold dark matter halos

High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile. Regardless

Evidence against dissipation-less dark matter from observations of galaxy haloes

THERE are two different types of missing (dark) matter: the unseen matter needed to explain the high rotation velocities of atomic hydrogen in the outer parts of spiral galaxies1,2, and the much
