Cosmic Recombination in the Presence of Primordial Magnetic Fields

Kavli Affiliate: Tom Abel | First 5 Authors: Karsten Jedamzik, Tom Abel, Yacine Ali-Haimoud, , | Summary: Primordial magnetic fields (PMFs) may explain observations of magnetic fields on extragalactic scales. They are most cleanly constrained by measurements of cosmic microwave background radiation (CMB) anisotropies. Their effects on cosmic recombination may even be at the heart […]

An outburst and FU Ori-type disk of a former low luminosity protostar

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Mizna Ashraf, Jessy Jose, Ho-Gyu Lee, Carlos Contreras Peña, Gregory Herczeg | Summary: Strong accretion outbursts onto protostars are associated with emission dominated by a viscously heated disk, which is characterized by high luminosities. We report the discovery and characterization of a strong mid-IR (3.4, 4.6 $mu$m) […]

ElasticLaneNet: A Geometry-Flexible Approach for Lane Detection

Kavli Affiliate: Feng Yuan | First 5 Authors: Yaxin Feng, Yuan Lan, Luchan Zhang, Yang Xiang, | Summary: The task of lane detection involves identifying the boundaries of driving areas. Recognizing lanes with complex and variable geometric structures remains a challenge. In this paper, we introduce a new lane detection framework named ElasticLaneNet (Elastic-interaction-energy guided […]

Spectrum Degeneracies from Quantum Evanescence

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Xiaochuan Lu, Tom Melia, , | Summary: We identify degeneracies in the energy spectra of quantum theories that occur at integer values of the continuous parameter $N$ of an analytically continued global $O(N)$ symmetry. The degeneracies are enforced by the requirement that evanescent states fall […]

Constraints on the spectrum of field theories with non-integer $O(N)$ symmetry from quantum evanescence

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Xiaochuan Lu, Tom Melia, , | Summary: We identify constraints in the energy spectra of quantum theories that have a global $O(N)$ symmetry, where $N$ is treated as a continuous parameter. We point out that a class of evanescent states fall out of the spectrum […]

Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Niek Bollemeijer, Phil Uttley, Arkadip Basak, Adam Ingram, Jakob van den Eijnden | Summary: In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent time lags. On short (~0.1 s) time-scales, these […]
