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$_2$) […]
Kavli Affiliate: Sander Otte | First 5 Authors: Minxing Xu, Robbie J. G. Elbertse, Ata Keşkekler, Giuseppe Bimonte, Jinwon Lee | Summary: The Casimir effect and superconductivity are foundational quantum phenomena whose interaction remains an open question in physics. How Casimir forces behave across a superconducting transition remains unresolved, owing to the experimental difficulty of […]
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, […]
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 […]
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 […]
Kavli Affiliate: Dan Luo | First 5 Authors: Dan Luo, Chengyuan Ma, Weiqin Li, Jun Wang, Wei Chen | Summary: With the advancement of speech synthesis technology, users have higher expectations for the naturalness and expressiveness of synthesized speech. But previous research ignores the importance of prompt selection. This study proposes a text-to-speech (TTS) framework […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Rui Xu, Dandan Xu, Lars Andersson, Pau Amaro Seoane, Lijing Shao | Summary: We put into test the idea of replacing dark energy by a vector field against the cosmic microwave background (CMB) observation using the simplest vector-tensor theory, where a massive vector field couples to […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Boris Bolliet, Anthony Challinor, William Handley, | Summary: The abundance of galaxy clusters as a function of mass and redshift is a well-established and powerful cosmological probe. Cosmological analyses based on galaxy cluster number counts have traditionally relied on explicitly computed likelihoods, which are often […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Yuxuan Chen, Shanshan Huang, Yunyao Cheng, Peng Chen, Zhongwen Rao | Summary: Time series classification (TSC) is an important task in time series analysis. Existing TSC methods mainly train on each single domain separately, suffering from a degradation in accuracy when the samples for training are insufficient […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Peter H. Sims, Harry T. J. Bevins, Anastasia Fialkov, Dominic Anstey, Will J. Handley | Summary: Observations of the Epoch of Reionization (EoR) have the potential to answer long-standing questions of astrophysical interest regarding the nature of the first luminous sources and their effects on the intergalactic […]
