Kavli Affiliate: Alexander P. Ji | First 5 Authors: Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu, Anirudh Chiti, Silvia Rossi | Summary: We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < rm[Fe/H] lesssim -1.3$). We find abundance patterns that are effectively […]

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Diksha Garg, Mary Hall Reno, Sameer Patel, Alexander Ruestle, Yosui Akaike | Summary: Using the Earth as a neutrino converter, tau neutrino fluxes from astrophysical point sources can be detected by tau-lepton-induced extensive air showers (EASs). Both muon neutrino and tau neutrino induced upward-going EAS signals […]

Kavli Affiliate: Paolo Privitera | First 5 Authors: Fraser Bradfield, Justin Albury, Jose Bellido, Ladislav Chytka, John Farmer | Summary: The Fluorescence detector Array of Single-pixel Telescopes (FAST) is one of several proposed designs for a next-generation cosmic-ray detector. Such detectors will require enormous collecting areas whilst also needing to remain cost-efficient. To meet these […]

Kavli Affiliate: Paolo Privitera | First 5 Authors: Shunsuke Sakurai, Justin Albury, Jose Bellido, Fraser Bradfield, Ladislav Chytka | Summary: Ultra-high energy cosmic rays (UHECRs), whose energy are beyond $10^{18}~mathrm{eV}$, are the most energetic particles we have ever detected. The latest results seem to indicate a heavier composition at the highest energies, complicating the search […]

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We model the interstellar dust content of the reionization era with a suite of cosmological, fluid-dynamical simulations of galaxies with stellar masses ranging from $sim 10^5 – 10^9 M_{odot}$ in the first $1.2$ billion years of […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Evan N. Kirby, Alexander P. Ji, Mikhail Kovalev, , | Summary: Whereas light element abundance variations are a hallmark of globular clusters, there is little evidence for variation in neutron-capture elements. A significant exception is M15, which shows a star-to-star dispersion in neutron-capture abundances of at […]

Kavli Affiliate: Wayne Hu | First 5 Authors: Jose María Ezquiaga, Wayne Hu, Rico K. L. Lo, , | Summary: Strongly lensed gravitational waves (GWs) from binary coalescence manifest as repeated chirps from the original merger. At the detectors, the phase of the lensed GWs and its arrival time differences will be consistent modulo a […]
