Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Yang Huang, Huawei Zhang, Haibo Yuan, Zhiying Huo | Summary: We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supergiant candidates have been properly derived from the qualified spectra released in LAMOST […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Qiang Yang, Weilin Xie, Congfan Wang, Bowen Li, Xin Li | Summary: In distributed fiber-optic sensing based on optical frequency domain reflectometry (OFDR), Doppler frequency shifts due to the changes of disturbances during one sweep period introduce demodulation errors that accumulate along both the distance and […]

Kavli Affiliate: Blake Sherwin | First 5 Authors: William R. Coulton, Adriaan J. Duivenvoorden, Zachary Atkins, Nicholas Battaglia, Elia Stefano Battistelli | Summary: The high electron temperature in galaxy clusters ($>1,$keV or $>10^7,$K) leads to corrections at the level of a few percent in their thermal Sunyaev-Zeldovich effect signatures. Both the size and frequency dependence […]
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 […]
Kavli Affiliate: Brian D. Nord | First 5 Authors: Shrihan Agarwal, Aleksandra Ćiprijanović, Brian D. Nord, , | Summary: Modeling strong gravitational lenses is computationally expensive for the complex data from modern and next-generation cosmic surveys. Deep learning has emerged as a promising approach for finding lenses and predicting lensing parameters, such as the Einstein […]
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 […]
