Cosmological Constraints on Dark Matter Interactions with Ordinary Matter
Manuel A. Buen-Abad, Rouven Essig, David McKeen +1
Dark matter interactions with electrons or protons during the early Universe leave imprints on the cosmic microwave background and the matter power spectrum, and can be probed thro…

Inspired by the work [Eur. Phys. J. C 78 (2018) 45], we study the linear tensor perturbation of both the flat and bent thick branes with inner structure in two-field mimetic gravit…
Seeding Supermassive Black Holes with Self-Interacting Dark Matter: A Unified Scenario with Baryons
Wei-Xiang Feng, Hai-Bo Yu, Yi-Ming Zhong
Observations show that supermassive black holes (SMBHs) with a mass of exist when the Universe is just of its current age. We propose a scenario where a se…

Christina Gao, Jia Liu, Lian-Tao Wang +3
The XENON1T collaboration has observed an excess in electronic recoil events below over the known background, which could originate from beyond-the-Standard-Model…
The Structure of Dissipative Dark Matter Halos
Ran Huo, Hai-Bo Yu, Yi-Ming Zhong
Dissipative dark matter self-interactions can affect halo evolution and change its structure. We perform a series of controlled N-body simulations to study impacts of the dissipati…
