Kavli Affiliate: Alexander P. Ji | First 5 Authors: Xiaowei Ou, Alexander P. Ji, Anna Frebel, Rohan P. Naidu, Guilherme Limberg | Summary: Neutron star mergers (NSMs) produce copious amounts of heavy r-process elements after a time delayed inspiral process. Once NSMs are present in a galaxy, r-process elements, such as Eu, are expected to […]
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, […]
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 […]
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. […]
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 […]
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 […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yue Pan, Anirudh Chiti, Alex Drlica-Wagner, Alexander P. Ji, Ting S. Li | Summary: We conducted an in-depth analysis of candidate member stars located in the peripheries of three ultra-faint dwarf (UFD) galaxy satellites of the Milky Way: Bo"otes I (Boo1), Bo"otes II (Boo2), and Segue […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Deveshi Buch, Ethan O. Nadler, Risa H. Wechsler, Yao-Yuan Mao, | Summary: We present Milky Way-est, a suite of 20 cosmological cold-dark-matter-only zoom-in simulations of Milky Way (MW)-like host halos. Milky Way-est hosts are selected such that they: ($i$) are consistent with the MW’s measured halo […]
Kavli Affiliate: Lee McCuller | First 5 Authors: Sander M. Vermeulen, Torrey Cullen, Daniel Grass, Ian A. O. MacMillan, Alexander J. Ramirez | Summary: The GQuEST (Gravity from the Quantum Entanglement of Space-Time) experiment uses tabletop-scale Michelson laser interferometers to probe for fluctuations in space-time. We present an interferometer design featuring a novel photon counting […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Chao-Jun Feng, , , | Summary: The curved spacetime induced by gravitational waves can give rise to visual effects such as geometric distortions and redshift structures in the observed image. By establishing a mapping from the object’s surface coordinates to the observer’s screen coordinates, we […]
