The GD-1 stellar stream perturber as a core-collapsed self-interacting dark matter halo
Xingyu Zhang, Hai-Bo Yu, Daneng Yang +1
The GD-1 stellar stream exhibits spur and gap structures that may result from a close encounter with a dense substructure. When interpreted as a dark matter subhalo, the perturber…
EDEN: Exploring Disks Embedded in N-body simulations of Milky-Way-mass halos from Symphony
Yunchong Wang, Philip Mansfield, Ethan O. Nadler +4
We investigate the impact of galactic disks on the tidal stripping of cold dark matter subhalos within Milky Way (MW)-mass halos () using…
CDM and SIDM Interpretations of the Strong Gravitational Lensing Object JWST-ER1
Demao Kong, Daneng Yang, Hai-Bo Yu
van Dokkum et al. (arXiv:2309.07969) reported the discovery of JWST-ER1, a strong lensing object at redshift , using data from the James Webb Space Telescope. The lens m…
Self-interacting dark matter interpretation of Crater II
Xingyu Zhang, Hai-Bo Yu, Daneng Yang +1
The satellite galaxy Crater II of the Milky Way is extremely cold and exceptionally diffuse. These unusual properties are challenging to understand in the standard model of cold da…
