Growing a nuclear star cluster from star formation and cluster mergers: The JWST NIRSpec view of NGC 4654

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Katja Fahrion, Torsten Böker, Michele Perna, Tracy L. Beck, Roberto Maiolino | Summary: We present a detailed study of the centre of NGC4654, a Milky Way-like spiral galaxy in the Virgo cluster that has been reported to host a double stellar nucleus, thus promising a rare view […]

Qubit frugal entanglement determination with the deep multi-scale entanglement renormalization ansatz

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Kushagra Garg, Zeeshan Ahmed, Andreas Thomasen, , | Summary: We study the deep multi-scale entanglement renormalization ansatz (DMERA) on quantum hardware and the causal cone of a subset of the qubits which make up the ansatz. This causal cone spans $O(M+log{N})$ physical qubits on a quantum device, […]

FlowWalker: A Memory-efficient and High-performance GPU-based Dynamic Graph Random Walk Framework

Kavli Affiliate: Jing Wang | First 5 Authors: Junyi Mei, Shixuan Sun, Chao Li, Cheng Xu, Cheng Chen | Summary: Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within a graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand a pre-processing buffer, causing substantial […]

Searching for Hyper-compact star clusters in the Milky Way using LAMOST and Gaia

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Haibo Yuan, Yilun Wang, Zexi Niu, Huawei Zhang | Summary: During the early merger of the Milky Way, intermediate-mass black holes in merged dwarf galaxies may have been ejected from the center of their host galaxies due to gravitational waves, carrying some central stars along. […]

Search for rare $b to dell^+ell^-$ transitions at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We present the results of a search for the $b to dell^+ell^-$ flavor-changing neutral-current rare decays $B^{+, 0} to (eta, omega, pi^{+,0}, rho^{+, 0}) e^+e^-$ and $B^{+, 0} to (eta, omega, pi^{0}, rho^{+}) mu^+mu^-$ using a […]

Microlensing near macro-caustics

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Luke Weisenbach, Timo Anguita, Jordi Miralda-Escudé, Masamune Oguri, Prasenjit Saha | Summary: Microlensing near macro-caustics is a complex phenomenon in which swarms of micro-images produced by micro-caustics form on both sides of a macro-critical curve. Recent discoveries of highly magnified images of individual stars in massive […]
