Reliable Transmission Spectrum Extraction with a Three-Parameter Limb Darkening Law

Kavli Affiliate: Sara Seager | First 5 Authors: Rosa E. Keers, Alexander I. Shapiro, Nadiia M. Kostogryz, Ana Glidden, Prajwal Niraula | Summary: Stellar limb darkening must be properly accounted for to accurately determine the radii of exoplanets at various wavelengths. The standard approach to address limb darkening involves either using laws with coefficients from […]

Coronagraph-based wavefront sensors for the high Strehl regime

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 […]

Finite-Momentum Pairing State in Unconventional Rashba Systems

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 […]

A measurement of atmospheric circular polarization with POLARBEAR

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 […]

Rare Event Classification with Weighted Logistic Regression for Identifying Repeating Fast Radio Bursts

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 […]

ATOMS: ALMA three-millimeter observations of massive star-forming regions — XVIII. On the origin and evolution of dense gas fragments in molecular shells of compact HII regions

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 […]
