Kavli Affiliate: Jia Liu | First 5 Authors: Rundong Fang, Rundong Fang, , , | Summary: We investigate long-range, purely leptophilic axial-vector interactions mediated by a light gauge boson $A’$ that couples to charged leptons and, by weak symmetry, to left-handed neutrinos. We analyze two realizations, a minimal effective model with muon-only couplings and an […]
Kavli Affiliate: Radomir Smida | First 5 Authors: Jakub Kmec, Jakub Kmec, , , | Summary: Ultra-high-energy cosmic rays (UHECRs) remain one of the greatest mysteries in astroparticle physics. The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a next-generation cosmic ray experiment which utilizes ground-based fluorescence telescopes designed to detect these extremely rare particles […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Giona Sala, Giona Sala, , , | Summary: Mergers of white dwarf binaries are a possible progenitor channel for Type Ia supernovae. While white dwarfs are abundant in the universe and relatively well understood, their gravitational wave signals have not yet been directly observed. In order […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Jonathan C. Tan, Jonathan C. Tan, , , | Summary: The Population III.1 theory for supermassive black hole (SMBH) formation predicts a very early ($zsim20-25$), transient phase, “The Flash”, of cosmic reionization powered by supermassive stars that are SMBH progenitors. The universe then quickly recombined to become […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Shinta Kasuya, Shinta Kasuya, , , | Summary: We numerically study the formation of the gauge-mediation type Q balls in the logarithmic square potential on three-dimensional lattices. We obtain the broad charge distribution of the Q ball of this type for the first time. The charge of […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Federico Esposito, Federico Esposito, , , | Summary: The distribution of molecular gas on small scales regulates star formation and the growth of supermassive black holes in galaxy centers, yet the role of active galactic nuclei (AGN) feedback in shaping this distribution remains poorly constrained. We investigate […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Joshua N. Benabou, Joshua N. Benabou, , , | Summary: The absence of a neutron electric dipole moment (EDM) constrains the quantum chromodynamics (QCD) theta angle to be less than one part in ten billion, posing the Strong $CP$ problem. We revisit two classes of proposed solutions. […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Meredith Neyer, Meredith Neyer, , , | Summary: We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman-$alpha$ emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization. We generate realistic LAE catalogs by combining accurate intrinsic Ly$alpha$ production and intergalactic transmission with an empirical model […]
Kavli Affiliate: Jing Wang | First 5 Authors: Sijia Li, Sijia Li, , , | Summary: The interstellar medium (ISM) in high-redshift galaxies exhibits significantly higher electron densities ($n_rm e$) than in the local universe. To investigate the origin of this trend, we analyze a sample of 9590 centrally star-forming galaxies with stellar masses greater […]
Kavli Affiliate: Jing Wang | First 5 Authors: Shihao Li, Shihao Li, , , | Summary: Although Multimodal Large Language Models (MLLMs) have demonstrated proficiency in video captioning, practical applications require captions that follow specific user instructions rather than generating exhaustive, unconstrained descriptions. Current benchmarks, however, primarily assess descriptive comprehensiveness while largely overlooking instruction-following capabilities. […]
