TOI-2119: A transiting brown dwarf orbiting an active M-dwarf from NASA’s TESS mission

Kavli Affiliate: Edward H. Morgan | First 5 Authors: Theron W. Carmichael, Jonathan M. Irwin, Felipe Murgas, Enric PallĂ©, Keivan G. Stassun | Summary: We report the discovery of TOI-2119b, a transiting brown dwarf (BD) that orbits and is completely eclipsed by an active M-dwarf star. Using light curve data from the Transiting Exoplanet Survey […]

Listing Maximal k-Plexes in Large Real-World Graphs

Kavli Affiliate: Yi Zhou | First 5 Authors: Zhengren Wang, Yi Zhou, Mingyu Xiao, Bakhadyr Khoussainov, | Summary: Listing dense subgraphs in large graphs plays a key task in varieties of network analysis applications like community detection. Clique, as the densest model, has been widely investigated. However, in practice, communities rarely form as cliques for […]

Weak Ergodicity Breaking in Non-Hermitian Many-body Systems

Kavli Affiliate: Zheng Zhu | First 5 Authors: Qianqian Chen, Shuai A. Chen, Zheng Zhu, , | Summary: The recent discovery of persistent revivals in the Rydberg-atom quantum simulator has revealed a weakly ergodicity-breaking mechanism dubbed quantum many-body scars, which are a set of nonthermal states embedded in otherwise thermal spectra. Until now, such a […]

Mitigating Closed-model Adversarial Examples with Bayesian Neural Modeling for Enhanced End-to-End Speech Recognition

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao-Han Huck Yang, Zeeshan Ahmed, Yile Gu, Joseph Szurley, Roger Ren | Summary: In this work, we aim to enhance the system robustness of end-to-end automatic speech recognition (ASR) against adversarially-noisy speech examples. We focus on a rigorous and empirical "closed-model adversarial robustness" setting (e.g., on-device or […]

Massive Galaxy Mergers Have Distinctive Global HI Profiles

Kavli Affiliate: Jing Wang | First 5 Authors: Pei Zuo, Luis C. Ho, Jing Wang, Niankun Yu, Jinyi Shangguan | Summary: The global 21 cm HI emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas. Galaxy interactions significantly influence the HI disk and imprint observable […]

Observation and origin of non-thermal hard X-rays from Jupiter

Kavli Affiliate: Melania Nynka | First 5 Authors: Kaya Mori, Charles Hailey, Gabriel Bridges, Shifra Mandel, Amani Garvin | Summary: Electrons accelerated on Earth by a rich variety of wave scattering or stochastic processes generate hard non-thermal X-ray bremsstrahlung up to >~ 1 MeV and power Earth’s various types of aurorae. Although Jupiter’s magnetic field […]
