Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Masahiro Ibe, Yuhei Nakayama, Satoshi Shirai, Keiichi Watanabe | Summary: Metastable cosmic strings appear in models of new physics with a two-step symmetry breaking $Gto Hto 1$, where $pi_1(H)neq 0$ and $pi_1(G)=0$. They decay via the monopole-antimonopole pair creation inside. Conventionally, the breaking rate has […]
Kavli Affiliate: Jia Liu | First 5 Authors: Tian Xia, Jia Liu, Zhiping Chen, , | Summary: In this paper, we study the distributionally robust joint chance constrained Markov decision process. {Utilizing the logarithmic transformation technique,} we derive its deterministic reformulation with bi-convex terms under the moment-based uncertainty set. To cope with the non-convexity and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nadia Qutob, Razieh Emami, Kung-Yi Su, Randall Smith, Lars Hernquist | Summary: We make an in-depth analysis of different AGN jet models’ signatures, inducing quiescence in galaxies with a halo mass of $10^{12} M_odot$. Three jet models, including cosmic ray-dominant, hot thermal, and precessing kinetic jets, are […]
Kavli Affiliate: Jing Wang | First 5 Authors: Qi Xu, Lijie Wang, Jing Wang, Lin Cheng, Song Chen | Summary: In recent years, analog circuits have received extensive attention and are widely used in many emerging applications. The high demand for analog circuits necessitates shorter circuit design cycles. To achieve the desired performance and specifications, […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Jakob T. Faber, Daniele Michilli, Ryan Mckinven, Jianing Su, Aaron B. Pearlman | Summary: We present the discovery of twelve thus far non-repeating fast radio burst (FRB) sources, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources were selected from a database comprising […]
Kavli Affiliate: Ronald Remillard | First 5 Authors: Yanan Wang, Dheeraj R. Pasham, Diego Altamirano, Andres Gurpide, Noel Castro Segura | Summary: The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our 1000+ days NICER, […]

Kavli Affiliate: Hu Zhan | First 5 Authors: Li Shao, Hu Zhan, Chao Liu, Haonan Chi, Qiuyan Luo | Summary: We tested a new model of CMOS detector manufactured by the Gpixel Inc, for potential space astronomical application. In laboratory, we obtain some bias images under the typical application environment. In these bias images, clear […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Ioana Coman, Myungbo Shim, Masahito Yamazaki, Yehao Zhou, | Summary: We study Vertex Operator Algebras (VOAs) obtained from the H-twist of 3d $mathcal{N}=4$ linear quiver gauge theories. We find that H-twisted VOAs can be regarded as the ”chiralization” of the extended Higgs branch: many of the ingredients […]
