Kavli Affiliate: Erin Kara | First 5 Authors: XRISM Collaboration, Marc Audard, Hisamitsu Awaki, Ralf Ballhausen, Aya Bamba | Summary: The XRISM Resolve microcalorimeter array measured the velocities of hot intracluster gas at two positions in the Coma galaxy cluster: 3’x3′ squares at the center and at 6′ (170 kpc) to the south. We find […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Wenpeng Xing, Dezhang Kong, Changting Lin, Meng Han | Summary: Safety alignment in large language models (LLMs) is achieved through fine-tuning mechanisms that regulate neuron activations to suppress harmful content. In this work, we propose a novel approach to induce disalignment by identifying and modifying […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Aoran Sun, Da Wei, Yiyu Zhang, Fangfu Ye, Rudolf Podgornik | Summary: We study an active Brownian run-and-tumble particle (ABRTP) model, that consists of an active Brownian run state during which the active velocity of the particle diffuses on the unit circle, and a tumble state during […]

Woermann, Thilo Kalbhenn, Barry Giesbrecht, Christian G. Bien, Olaf Sporns, Michael S. Gazzaniga, Lukas J. Volz and Michael B. Miller | Summary: Sensorimotor processing in the human brain is largely […]

Kavli Affiliate: Lile Wang | First 5 Authors: Paul F. Goldsmith, Shengzhe Wang, Xin Wang, Raphael Skalidis, Gary A. Fuller | Summary: We report JWST MIRI/MRS observations of the H2 S(1) 17.04 micron transition in two regions in the boundary of the Taurus Molecular Cloud. The two regions, denoted Edge (near the relatively sharp boundary […]
Kavli Affiliate: Leon Balents | First 5 Authors: Nisarga Paul, Takamori Park, Jung Hoon Han, Leon Balents, | Summary: We study the gyrotropic magnetic effect (GME), the low-frequency limit of optical gyrotropy, in metals and semimetals coupled to chiral spin textures. In these systems, the chiral spin texture which lacks inversion symmetry can imprint itself […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Shao-Dong Zhao, , , | Summary: At the Galactic Centre, we can expect a population of a few tens of early extreme-mass ratio inspirals (E-EMRIs) and extremely large mass ratio inspirals (XMRIs). Depending on their evolutionary stage, they can be highly eccentric, with […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: We investigate the properties of cosmological ionization fronts during the Epoch of Reionization using the CROC simulations. By analyzing reionization timing maps, we characterize ionization front velocities and curvatures and their dependence on the density structure of […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Frank J. Qu, Fei Ge, W. L. Kimmy Wu, Irene Abril-Cabezas, Mathew S. Madhavacheril | Summary: We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Telescope (ACT), the South Pole […]
