Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Lu Chen, , , | Summary: In cosmology, the fine-structure constant can affect the whole ionization history. However, the previous works confine themselves to the recombination epoch and give various strong constraints on the fine-structure constant. In this paper, we also take the reionization epoch […]
Kavli Affiliate: Jing Wang | First 5 Authors: Hye-Jin Park, Se-Heon Oh, Jing Wang, Yun Zheng, Hong-Xin Zhang | Summary: We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Group at a distance of ~ 490 kpc. We perform profile decomposition of line-of-sight velocity […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Beibei Zhang, , , | Summary: We study a large deviation principle for a reflected stochastic partial differential equation on infinite spatial domain. A new sufficient condition for the weak convergence criterion proposed by Matoussi, Sabbagh and Zhang ({it Appl. Math. Optim.} 83: 849-879, 2021) […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Steven R. Ehlert, Riccardo Ferrazzoli, Andrea Marinucci, Herman L. Marshall, Riccardo Middei | Summary: We present measurements of the polarization of X-rays in the $2-8 thinspace mathrm{keV}$ band from the nucleus of the radio galaxy Centaurus A (Cen A), using a 100ks observation from the Imaging […]
Kavli Affiliate: Takeo Higuchi | First 5 Authors: Latika Aggarwal, Swagato Banerjee, Sunil Bansal, Florian Bernlochner, Michel Bertemes | Summary: Belle II is an experiment operating at the intensity frontier. Over the next decades, it will record the decay of billions of bottom mesons, charm hadrons, and tau leptons produced in 10 GeV electron-positron collisions […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Will M. Farr, Maya Fishbach, Daniel E. Holz, Erik Katsavounidis | Summary: We constrain the distribution of merging compact binaries across the celestial sphere using the GWTC-3 catalog from the LIGO-Virgo-KAGRA Collaborations’ (LVK) third observing run. With 63 confident detections from O3, we constrain […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Wen-Qing Guo, Xiaoyuan Huang, Jia Liu | Summary: Dark photon can be the ultralight dark matter candidate, which can interact with the Standard Model particles via the kinetic mixing. We propose to look for ultralight dark photon dark matter (DPDM) with local absorption […]
