Kavli Affiliate: Anna Frebel | First 5 Authors: , , , , | Summary: We investigate how stellar feedback from the first stars (Population III) distributes metals through the interstellar and intergalactic medium using the star-by-star cosmological hydrodynamics simulation, Aeos. We find that energy injected from the supernovae of the first stars is enough to […]
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: Dan Luo | First 5 Authors: Yanbiao Ji, Yue Ding, Dan Luo, Chang Liu, Yuxiang Lu | Summary: Graph-based recommender systems have achieved remarkable effectiveness by modeling high-order interactions between users and items. However, such approaches are significantly undermined by popularity bias, which distorts the interaction graph’s structure, referred to as topology bias. […]
