Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter
(DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The …

Abstract van Dokkum et al. reported the discovery of JWST-ER1, a strong lensing object at
redshift z≈ 2, using data from the James Webb Space Telescope. The lens mass within the …

We study the effect of self-interacting dark matter (SIDM) and baryons on the shape of early-
type galaxies (ETGs) and their dark matter haloes, comparing them to the predictions of the …

Galaxy-scale strongly lensed systems have been shown to provide a unique technique for
exploring the underlying physics of dark matter at sub-galactic scales. In the past, much …

We systemically evaluate the performance of the self-interacting dark matter (SIDM) halo
model proposed in Ref. Yang et al.(2023) with matched halos from high-resolution …

A dark sector with non-abelian gauge symmetry provides a sound framework to justify stable
dark matter (DM) candidates. We consider scalar fields charged under a $ SU (N) $ gauge …

A bstract In models with spontaneous symmetry breaking by scalar fields in large group
representations, we observe that some of the scalar masses can be loop-suppressed with …

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 …

In another paper published in this issue, we underscored the fundamental and mathematical
difficulties in unifying general relativity and quantum field theories. We also proposed an …

The gravitational lensing signal produced by a galaxy or a galaxy cluster is determined by its
total matter distribution, providing us with a way to directly constrain their dark matter …
