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 […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Z. Pan, F. Bianchini, W. L. K. Wu, P. A. R. Ade, Z. Ahmed | Summary: We present a measurement of gravitational lensing over 1500 deg$^2$ of the Southern sky using SPT-3G temperature data at 95 and 150 GHz taken in 2018. The lensing amplitude relative to […]

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 […]
