Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Anatoli Fedynitch, Roger D. Blandford, , | Summary: The origin of Ultra High Energy Cosmic Rays is a 60-year old mystery. We show that with more events at the highest energies (above 150~EeV) it may be possible to limit the character of the sources […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: We present single quasiparticle devices as new dark matter (DM) detectors. The threshold of these devices is set by the cooper pair binding energy, and is therefore so low that they can detect DM as light as […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: We point out that power measurements of single quasiparticle devices open a new avenue to detect dark matter (DM). The threshold of these devices is set by the Cooper pair binding energy, and is therefore so low […]
Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Peng-Xiong Ma, Zhi-Hui Xu, Qiang Yuan, Xiao-Jun Bi, Yi-Zhong Fan | Summary: Precise measurements of the boron-to-carbon and boron-to-oxygen ratios by DAMPE show clear hardenings around $100$ GeV/n, which provide important implications on the production, propagation, and interaction of Galactic cosmic rays. In this work we […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to cosmological constraints and […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Akash Biswas, Bidya Binay Karak, Robert Cameron, , | Summary: A striking feature of the solar cycle is that at the beginning, sunspots appear around mid-latitudes, and over time the latitudes of emergences migrate towards the equator.The maximum level of activity (e.g., sunspot number) varies from cycle […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: LUX Collaboration, D. S. Akerib, S. Alsum, H. M. Araújo, X. Bai | Summary: Dual-phase xenon time projection chamber (TPC) detectors have demonstrated superior search sensitivities to dark matter over a wide range of particle masses. To extend their sensitivity to include low-mass dark matter interactions, […]
