Kavli Affiliate: Bruce Macintosh | First 5 Authors: Vincent Chambouleyron, J. Kent Wallace, Rebecca Jensen-Clem, Bruce Macintosh, | Summary: A crucial component of the high-contrast instrumental chain in astronomy is the wavefront sensor (WFS). A key property of this component is its sensitivities, which reflect its ability to efficiently use incoming photons to encode the […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Song-Bo Zhang, Ning Hao, , | Summary: In systems with unconventional Rashba bands, we propose that a finite-momentum pairing state can emerge without the need for an external magnetic field. We analyze the phase transition from a zero-momentum Bardeen-Cooper-Schrieffer (BCS) state to a finite-momentum pairing […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Takuro Fujino, Satoru Takakura, Shahed Shayan Arani, Darcy Barron, Carlo Baccigalupi | Summary: At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth’s magnetic field. We report a measurement of the signal in the 150 GHz band […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Antonio Herrera-Martin, Radu V. Craiu, Gwendolyn M. Eadie, David C. Stenning, Derek Bingham | Summary: An important task in the study of fast radio bursts (FRBs) remains the automatic classification of repeating and non-repeating sources based on their morphological properties. We propose a statistical model that […]
Kavli Affiliate: Ke Wang | First 5 Authors: Siju Zhang, Tie Liu, Ke Wang, Annie Zavagno, Guido Garay | Summary: Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typical diameter of 0.4 pc that are […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Marbely Micolta, Nuria Calvet, Thanawuth Thanathibodee, Gladis Magris C., Carlo F. Manara | Summary: We present a study of the abundance of calcium in the innermost disk of 70 T Tauri stars in the star-forming regions of Chamaeleon I, Lupus and Orion OB1b. We use calcium […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Kaia R. Atzberger, Sam A. Usman, Alexander P. Ji, Lara R. Cullinane, Denis Erkal | Summary: Chemical abundances of stellar streams can be used to determine the nature of a stream’s progenitor. Here we study the progenitor of the recently discovered Leiptr stellar stream, which was […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Ellen G. Zweibel, Nickolay Y. Gnedin, , | Summary: We investigate the 1D plane-parallel front connecting the warm ($10^4$ K) and hot ($10^6$ K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CRs) in shaping these transition layers. We […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Large pre-trained models exhibit impressive zero-shot performance across diverse tasks, but fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade generalization on other tasks. To address this challenge, we introduce LiNeS, […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon, Aida Kirichenko, Kenzie Nimmo | Summary: We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localization program on the EVN, […]
