Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Torsten Åkesson, Cameron Bravo, Liam Brennan, Lene Kristian Bryngemark, Pierfrancesco Butti | Summary: The Light Dark Matter eXperiment (LDMX) is an electron-beam fixed-target experiment designed to achieve comprehensive model independent sensitivity to dark matter particles in the sub-GeV mass region. An upgrade to the LCLS-II accelerator will […]

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 […]
