Kavli Affiliate: Qingjuan Yu | First 5 Authors: Xiao Guo, Qingjuan Yu, Youjun Lu, , | Summary: Massive black holes (MBHs) exist in the Galactic center (GC) and other nearby galactic nuclei. As natural outcome of galaxy mergers, some MBHs may have a black hole (BH) companion. In this paper, assuming that the MBHs in […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Jianquan Ge, Ya Tao, Yi Zhou, , | Summary: For compact submanifolds in Euclidean and Spherical space forms with Ricci curvature bounded below by a function $alpha(n,k,H,c)$ of mean curvature, we prove that the submanifold is either isometric to the Einstein Clifford torus, or a topological sphere […]
Kavli Affiliate: Sara Seager | First 5 Authors: H. N. Smitha, Alexander I. Shapiro, Veronika Witzke, Nadiia M. Kostogryz, Yvonne C. Unruh | Summary: Accurate calculations of starspot spectra are essential for multiple applications in astronomy. The current standard is to represent starspot spectra by spectra of stars that are cooler than the quiet star […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report measurements of the absolute branching fractions $mathcal{B}(B_s^0 to D_s^{pm} X)$, $mathcal{B}(B_s^0 to D^0/bar{D}^0 X)$, and $mathcal{B}(B_s^0 to D^{pm} X)$, where the latter is measured for the first time. The results are based on a […]
Kavli Affiliate: Long Zhang | First 5 Authors: Hongting Hou, Long Zhang, , , | Summary: Motivated by the recent observation of real-space edge modes with ultracold atoms [Braun et al., Nat. Phys. 20, 1306 (2024)], we investigate the preparation and detection of anomalous counterpropagating edge states — a defining feature of the anomalous Floquet […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan, Chenyang Ji, Zitao Lin | Summary: The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Jingtao Ding, Yunke Zhang, Yu Shang, Yuheng Zhang, Zefang Zong | Summary: The concept of world models has garnered significant attention due to advancements in multimodal large language models such as GPT-4 and video generation models such as Sora, which are central to the pursuit of artificial […]
Kavli Affiliate: Noah A. Kurinsky | First 5 Authors: Chao-Lin Kuo, Chelsea L. Bartram, Aaron S. Chou, Taj A. Dyson, Noah A. Kurinsky | Summary: We provide a comprehensive comparison of linear amplifiers and microwave photon-counters in axion dark matter experiments. The study is done assuming a range of realistic operating conditions and detector parameters, […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Xihan Ji, Cosimo Marconcini, Isabella Lamperti | Summary: Studying the distribution and properties of ionised gas in outflows driven by AGN is crucial for understanding the feedback mechanisms at play in extragalactic environments. In this study, we explore the connection between ionised outflows […]
