Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, XRISM Collaboration, , , | Summary: Galaxy clusters, the Universe’s largest halo structures, are filled with 10-100 million degree X-ray-emitting gas. Their evolution is shaped by energetic processes such as feedback from supermassive black holes (SMBHs) and mergers with other cosmic structures. The imprints of […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Linqing Wang, Linqing Wang, , , | Summary: Recent advancements in text-to-image (T2I) diffusion models have demonstrated remarkable capabilities in generating high-fidelity images. However, these models often struggle to faithfully render complex user prompts, particularly in aspects like attribute binding, negation, and compositional relationships. This leads […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Yuansheng Tao, Yuansheng Tao, , , | Summary: The sixth generation (6G) wireless networks require dynamic spectrum management to optimize the utilization of scarce spectral resources and support emerging integrated sensing and communication (ISAC) applications. This necessitates real-time spectrum sensing (RT-SS) capability with ultrawide measurement range, compact […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Tony Wells, Tony Wells, , , | Summary: We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 and TIC 339607421. TIC 339607421 hosts an M-dwarf companion ($M_B = 0.294 pm 0.013 : […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, SuperCDMS Collaboration, , , | Summary: We present constraints on low mass dark matter-electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water […]
Kavli Affiliate: Martin Haehnelt | First 5 Authors: Louise Welsh, Louise Welsh, , , | Summary: We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are identified along a given […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Masaki Okada, Masaki Okada, , , | Summary: We point out that fermionic unitary operators which anticommute among themselves appear in various situations in quantum field theories with anomalies in the Hamiltonian formalism. To illustrate, we give multiple derivations of the fact that position-dependent $U(1)$ transformations of […]
Kavli Affiliate: T. Higuchi | First 5 Authors: B. Algohi, B. Algohi, , , | Summary: We report the first results on ultracold neutron production from a new spallation-driven superfluid $^4$He (He-II) source at TRIUMF, which is being prepared for a new, precise measurement of the neutron electric dipole moment. A total of $(9.3 pm […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Simon May, Simon May, , , | Summary: The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to $m > 3 times 10^-19,mathrmeV$. This constraint, which excludes the "fuzzy" range of ultra-light dark matter from comprising all of the DM, […]
