Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, , , | Summary: One of the most exciting and pressing issues in cosmology today is the discrepancy between some measurements of the local Hubble constant and other values of the expansion rate inferred from the cosmic microwave background (CMB) […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmology. In this work, motivated by the […]

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Johannes Eser, Angela V. Olinto, Lawrence Wiencke, , | Summary: Observing ultra-high energy cosmic rays (UHECR) and very high energy (VHE) neutrinos from space is a promising way to measure their extremely low fluxes by significantly increasing the observed volume. The Extreme Universe Space Observatory on […]

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Pablo Torne, Kuo Liu, Ralph P. Eatough, Jompoj Wongphechauxsorn, James M. Cordes | Summary: The Event Horizon Telescope (EHT) observed in 2017 the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz ($lambda$=1.3 mm). The […]
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 […]
