Properties and observables of massive galaxies in self-interacting dark matter cosmologies
Claudio Mastromarino, Giulia Despali, Lauro Moscardini +3
We use hydrodynamical cosmological simulations to test the differences between cold and self-interacting dark matter models (CDM and SIDM) in the mass range of massive galaxies ($1…
Why weak lensing cluster shapes are insensitive to self-interacting dark matter
Andrew Robertson, Eric Huff, Katarina Markovic
We investigate whether the shapes of galaxy clusters inferred from weak gravitational lensing can be used as a test of the nature of dark matter. We analyse mock weak lensing data,…
Weak lensing in the blue: a counter-intuitive strategy for stratospheric observations
Mohamed M. Shaaban, Ajay S. Gill, Jacqueline McCleary +24
The statistical power of weak lensing measurements is principally driven by the number of high redshift galaxies whose shapes are resolved. Conventional wisdom and physical intuiti…
The local dark matter distribution in self-interacting dark matter halos
Elham Rahimi, Evan Vienneau, Nassim Bozorgnia +1
We study the effects of dark matter self-interactions on the local dark matter distribution in selected Milky Way-like galaxies in the EAGLE hydrodynamical simulations. The simulat…
Scanning For Dark Matter Subhalos in Hubble Space Telescope Imaging of 54 Strong Lenses
James W. Nightingale, Qiuhan He, Xiaoyue Cao +9
The cold dark matter (DM) model predicts that every galaxy contains thousands of DM subhalos; almost all other DM models include a physical process that smooths away the subhalos.…
Astrophysical Tests of Dark Matter Self-Interactions
Susmita Adhikari, Arka Banerjee, Kimberly K. Boddy +11
Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the Standard Model that have dark sectors with light mediators or strong dynamics. The self-i…
