Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Huangyu Xiao, , | Summary: Wave or fuzzy dark matter that is produced with relativistic wavenumbers exhibits free streaming effects analogous to warm or hot particle dark matter with relativistic momenta. Axions produced after inflation provide such a warm or mildly relativistic candidate, […]
Kavli Affiliate: Lindsey Bleem | First 5 Authors: Markus Michael Rau, Florian Kéruzoré, Nesar Ramachandra, Lindsey Bleem, | Summary: Galaxy clusters are one of the most powerful probes to study extensions of General Relativity and the Standard Cosmological Model. Upcoming surveys like the Vera Rubin Observatory’s Legacy Survey of Space and Time are expected to […]
Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: Christopher J. Shallue, Julian B. Muñoz, Gordan Z. Krnjaic, , | Summary: We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If those dark-sector particles are stable, they would survive to the present […]

Kavli Affiliate: Salman Habib | First 5 Authors: Katrin Heitmann, Thomas Uram, Nicholas Frontiere, Salman Habib, Adrian Pope | Summary: In this paper we describe the set of “New Worlds Simulations”, three very large cosmology simulations, Qo’noS, Vulcan, and Ferenginar, that were carried out on the Summit supercomputer with the Hardware/Hybrid Cosmology Code, HACC. The […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Byung Ju Park, Jae Jin Choi, Eunju Jeon, Jinyu Kim, Kyungwon Kim | Summary: We report new constraints on axion-like particles (ALPs) using data from the NEON experiment, which features a 16.7 kg of NaI(Tl) target located 23.7 meters from a 2.8 GW thermal power nuclear reactor. […]

Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: We discuss the possibility that the two nearby resonances observed by BESIII partially below the ,$pbar p$, threshold might be due to mixing between two metastable states with the same $J^{PC}=0^{-+}$ quantum numbers, but rather different internal […]
