Massive Black Hole Seed Formation in Strong X-ray Environments at High Redshift

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kazutaka Kimura, Kohei Inayoshi, Kazuyuki Omukai, , | Summary: Direct collapse of pristine gas in early galaxies is a promissing pathway for forming supermassive black holes (BHs) powering active galactic nuclei (AGNs) at the epoch of reionization (EoR). This seeding mechanism requires suppression of molecular hydrogen (H$_2$) […]

Do We Know How to Model Reionization?

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I compare the power spectra of the radiation fields from two recent sets of fully-coupled simulations that model cosmic reionization: "Cosmic Reionization On Computers" (CROC) and "Thesan". While both simulations have similar power spectra of the radiation sources, […]

Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response

Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Xiaoyang Huang, Lucile Savary, Leon Balents, | Summary: We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-diagonalize the dynamics. Expanding to the second order in gradients, which is beyond […]

Cosmogenic Neutrino Point Source and KM3-230213A

Kavli Affiliate: Zhuo Li | First 5 Authors: Qinyuan Zhang, Tian-Qi Huang, Zhuo Li, , | Summary: Cosmogenic neutrinos (CNs) are produced by ultra-high energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e, the neutrino spectrum, and angular profile as functions of time, by assuming that […]
