The dearth of high-mass hydrogen-atmosphere metal-polluted white dwarfs within 40 pc

Posted by dbos Harvard

Kavli Affiliate: David Charbonneau | First 5 Authors: Tim Cunningham, Pier-Emmanuel Tremblay, Mairi O’Brien, Evan B. Bauer, Mark A. Hollands | Summary: We present a population synthesis model which addresses the different mass distributions of the metal-polluted and non-metal-polluted hydrogen-atmosphere white dwarfs identified in volume-limited samples. Specifically, metal-pollution has been observed to be rare in […]

The role of effective mass and long-range interactions in the band-gap renormalization of photo-excited semiconductors

Posted by dbos Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Cian C. Reeves, Scott K. Cushing, Vojtech Vlcek, , | Summary: Understanding how to control changes in electronic structure and related dynamical renormalizations by external driving fields is the key for understanding ultrafast spectroscopy and applications in electronics. Here we focus on the band-gap’s modulation by […]

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

Posted by dbos Stanford

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

Posted by dbos Berkeley

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 […]

Frequency-resolved time lags due to X-ray disk reprocessing in AGN

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Christos Panagiotou, Iossif Papadakis, Erin Kara, Marios Papoutsis, Edward M. Cackett | Summary: Over the last years, a number of broadband reverberation mapping campaigns have been conducted to explore the short-term UV and optical variability of nearby AGN. Despite the extensive data collected, the origin of the […]

Exact Results in Chiral Gauge Theories with Flavor

Posted by dbos Tokyo

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