Constraining the cross-section of dark matter with giant radial arcs in galaxy clusters

J. Vega-Ferrero et al.

Summary: The study compares the statistics and morphology of giant arcs in galaxy clusters using different models, finding that self-interacting dark matter produces fewer but more magnified arcs. The probability of interaction is higher in colliding clusters and in denser regions.

Velocity-dependent self-interacting dark matter from groups and clusters of galaxies

Laura Sagunski et al.

Summary: This study investigates the self-interactions of dark matter in relaxed galaxy groups and clusters, revealing a mild preference for a nonzero cross section compared to cold collisionless dark matter. The analysis utilizes observational data and the Jeans formalism to robustly constrain the self-interaction cross section, providing insights into the behavior of dark matter in different cosmic structures.

The surprising accuracy of isothermal Jeans modelling of self-interacting dark matter density profiles

Andrew Robertson et al.

Summary: Recent research has investigated a method for predicting the density profiles of galaxies and galaxy clusters containing self-interacting dark matter, and tested its accuracy using cosmological simulations. The isothermal Jeans model was found to provide an accurate description of simulated SIDM density profiles across a wide range of halo masses.

Constraining velocity-dependent self-interacting dark matter with the Milky Way's dwarf spheroidal galaxies

Camila A. Correa

Summary: The study investigates the potential signature of self-interacting dark matter (SIDM) based on the observed anticorrelation between central dark matter (DM) densities of bright Milky Way dwarf spheroidal galaxies (dSphs) and their orbital pericentre distances. By analyzing the range of SIDM scattering cross-section per unit mass, the research finds that different dSph models require varying values of sigma/m(chi) to reproduce the observed central DM densities. Larger cross-sections are correlated with lower collision velocities of DM particles within each subhalo's core, leading to a proposed SIDM particle model involving a DM particle with a mass m(chi) = 53.93 +/- 9.81 GeV interacting through a light mediator of mass m(phi) = 6.6 +/- 0.43 MeV. This cross-section-velocity relation explains the diverse DM profiles of MW dSph satellites and matches observational constraints on larger scales.

The central densities of Milky Way-mass galaxies in cold and self-interacting dark matter models

Omid Sameie et al.

Summary: The study demonstrates that cosmological zoom-in simulations of self-interacting dark matter (SIDM) haloes result in higher star formation rates and more massive galaxies at early times, with more concentrated dark matter density profiles compared to cold dark matter (CDM) models. The presence of a dense stellar component enhances the thermalization process in SIDM haloes, leading to higher central dark matter densities. Overall, SIDM haloes are more responsive to the presence of a massive baryonic distribution than their CDM counterparts.

Strong lensing signatures of self-interacting dark matter in low-mass haloes

Daniel Gilman et al.

Summary: Core formation and runaway core collapse in models with self-interacting dark matter significantly change the density profiles of collapsed haloes. Strong gravitational lenses in quadruple image systems can be used to detect the unique properties of SIDM haloes and constrain the interaction cross-section. Predictions suggest that self-interactions at low velocities and the structure of SIDM on sub-galactic scales can be studied using compact sources and constraining the amplitude and velocity dependence of the interaction cross-section.

Dissipative dark matter on FIRE - I. Structural and kinematic properties of dwarf galaxies

Xuejian Shen et al.

Summary: The study investigates the effects of dissipative self-interacting dark matter in cosmological simulations, exploring the parameter space. Low-mass dwarf galaxies exhibit cuspy dark matter density profiles with a power-law slope of approximately -1.5. Models with higher cross-sections show dark matter rotation and halo deformation, but do not result in baryon-like thin 'dark discs'.

The onset of gravothermal core collapse in velocity-dependent self-interacting dark matter subhaloes

Hannah C. Turner et al.

Summary: This study investigates the gravitational collapse caused by dark matter self-interactions in explaining the diversity of the Milky Way satellite central dynamical masses. Using an N-body simulation, the vd100 model with velocity-dependent SIDM is compared to other dark matter models, showing higher maximum circular velocities for the vd100 haloes. The collapsed haloes with high V-max values at z = 1 have density profiles described by single power laws, indicating the need for tailored simulations to accurately model the runaway instability at scales <1 kpc.

Simulations of the merging galaxy cluster Abell 2034: what determines the level of separation between gas and dark matter

Micheli T. Moura et al.

Summary: Cluster mergers are important for studying dark matter and intracluster gas behavior, with dissociative collisions being able to separate gas from dark matter. Abell 2034, at z = 0.114, consists of two substructures with a mass ratio of about 1:2.2, showing clear dissociative features observed through X-rays and gravitational lensing, with the X-ray emission peak offcentered from the dark matter peak.

The impact of inelastic self-interacting dark matter on the dark matter structure of a Milky Way halo

Kun Ting Eddie Chua et al.

Summary: The study examines the effects of inelastic dark matter self-interactions on the internal structure of a simulated Milky Way-size halo. Inelastic collisions reduce the central density of the halo, increase core size, and isotropize orbits. The velocity distribution of dark matter particles in the inelastic SIDM model differs significantly from the CDM model, with high-speed particles resulting from inelastic collisions potentially leaving distinct signatures in direct detection experiments.

The surprising accuracy of isothermal Jeans modelling of self-interacting dark matter density profiles

Andrew Robertson et al.

Summary: The study utilizes an isothermal Jeans model to predict SIDM density profiles and tests it against cosmological simulations, finding that the model provides an accurate description of simulated SIDM density profiles as the Navarro-Frenk-White profile does of CDM haloes. The model works effectively across the entire halo mass range studied, with the tightest constraints expected to come from dwarf galaxies and galaxy clusters.
