Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: We interpret the 1.3mm VLBI observations made by the Event Horizon Telescope of the black hole in M87. It is proposed that, instead of being a torus of accreting gas, the observed annular ring is a rotating, magnetically-dominated ergomagnetosphere […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Abel L. Peirson, Ioannis Liodakis, Roger W. Romani, , | Summary: Both leptonic and hadronic emission processes may contribute to blazar jet emission; which dominates in blazars’s high energy emission component remains an open question. Some intermediate synchrotron peaked blazars transition from their low to high […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, M. F. Albakry, I. Alkhatib, D. W. P. Amaral, T. Aralis | Summary: Recent experiments searching for sub-GeV/$c^2$ dark matter have observed event excesses close to their respective energy thresholds. Although specific to the individual technologies, the measured excess event rates have been consistently […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Bruce Macintosh, Surjeet Rajendran, | Summary: We evaluate the potential for gravitational-wave (GW) detection in the frequency band from 10 nHz to 1 $mu$Hz using extremely high-precision astrometry of a small number of stars. In particular, we argue that non-magnetic, photometrically […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: K. R. Ferguson, A. J. Anderson, N. Whitehorn, P. A. R. Ade, M. Archipley | Summary: Ultralight axion-like particles (ALPs) are compelling dark matter candidates because of their potential to resolve small-scale discrepancies between $Lambda$CDM predictions and cosmological observations. Axion-photon coupling induces a polarization rotation in linearly […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: For the past decade, the BICEP/Keck collaboration has been operating a series of telescopes at the Amundsen-Scott South Pole Station measuring degree-scale $B$-mode polarization imprinted in the Cosmic Microwave Background (CMB) by primordial gravitational […]
Kavli Affiliate: Dale Li | First 5 Authors: Thomas Cecil, Clarence L. Chang, Shannon M. Duff, Dale Li, Rupak Mahapatra | Summary: Superconducting sensors are a key enabling technology for many HEP experiments with advances in sensor capabilities leading directly to expanded science reach. The unique materials and processes required for the fabrication of these […]
