We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are dark matter (DM) dominated systems, proposed as interesting targets for the indirect search of DM with gamma rays. The galaxies represent interesting cases with a strong disagreement between the density profiles (core vs. cusp) inferred from observations and numerical simulations. In this work, we addressed the problem by considering two different DM profiles, based on both the… Expand


Constraining dark matter annihilation with HSC low surface brightness galaxies
Searches for dark matter annihilation signals have been carried out in a number of target regions such as the Galactic Center and Milky Way dwarf spheroidal galaxies (dSphs), among a few others. HereExpand
Multiwavelength analysis of low surface brightness galaxies to study possible dark matter signature
Low surface brightness (LSB) galaxies have very diffuse, low surface density stellar discs that appear faint in optical images. They are very rich in neutral hydrogen (H i) gas, which extends wellExpand
On the Determination of Rotation Velocity and Dynamical Mass of Galaxies Based on Integrated H i Spectra
The integrated 21 cm H I emission profile of a galaxy encodes valuable information on the kinematics, spatial distribution, and dynamical state of its cold interstellar medium. The line width, inExpand

SHαDE: survey description and mass–kinematics scaling relations for dwarf galaxies
The Study of H α from Dwarf Emissions (SHαDE) is a high spectral resolution (R = 13 500) H α integral field survey of 69 dwarf galaxies with stellar masses 106 < M⋆ < 109 M⊙. The survey used FLAMESExpand
The asymptotic tidal remnants of cold dark matter subhaloes
We use N-body simulations to study the evolution of cuspy cold dark matter (CDM) halos in the gravitational potential of a massive host. Tidal mass losses reshape CDM halos, leaving behind boundExpand
Universal structure of dark matter haloes over a mass range of 20 orders of magnitude.
A cosmological simulation of the formation of present-day haloes over the full range of observed halo masses when dark matter is assumed to be in the form of weakly interacting massive particles of mass approximately 100 gigaelectronvolts is reported. Expand
Baryon-induced dark matter cores in the eagle simulations
We examine the formation of dark matter (DM) cores in dwarf galaxies simulated with the eagle model of galaxy formation. As in earlier work, we find that the star formation (SF) gas densityExpand
CLUMPY v3: γ-ray and ν signals from dark matter at all scales
This version of the CLUMPY code includes the mean extragalactic signal with several pre-defined options and keywords related to cosmological parameters, mass functions for the dark matter structures, and γ -ray absorption up to high redshift. Expand
