Hints of Primordial Magnetic Fields at Recombination and Implications for the Hubble Tension

Kavli Affiliate: Tom Abel | First 5 Authors: Karsten Jedamzik, Levon Pogosian, Tom Abel, , | Summary: Primordial Magnetic Fields (PMFs), long studied as potential relics of the early Universe, accelerate the recombination process and have been proposed as a possible way to relieve the Hubble tension. However, previous studies relied on simplified toy models. […]

Optimal sensing on an asymmetric exceptional surface

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Robert L. Cook, Liwen Ko, K. Birgitta Whaley, , | Summary: We study the connection between exceptional points (EPs) and optimal parameter estimation, in a simple system consisting of two counter-propagating traveling wave modes in a microring resonator. The unknown parameter to be estimated is the strength […]

Exact Results in Chiral Gauge Theories with Flavor

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Jacob M. Leedom, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact results in softly-broken supersymmetric $text{SU}(N_C)$ chiral gauge theories with charged fermions in one antisymmetric, $N_F$ fundamental, and $N_C+N_F-4$ anti-fundamental representations. We achieve this by considering the supersymmetric version of these theories […]

JWST’s First View of Tidal Disruption Events: Compact, Accretion-Driven Emission Lines & Strong Silicate Emission in an Infrared-selected Sample

Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Kishalay De, Christos Panagiotou, Erin Kara, Anna-Christina Eilers | Summary: Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises from the reprocessing of intrinsic emission into thermal MIR emission by […]
