The realm of Aurora. Density distribution of metal-poor giants in the heart of the Galaxy

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov, Andrey Kravtsov, Elliot Y. Davies | Summary: The innermost portions of the Milky Way’s stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted view of the density distribution of […]

Blind source separation of the stellar halo

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov, Stephanie Monty, GyuChul Myeong | Summary: The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and textit{in-situ} evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures […]

Observation of Quantum Criticality Class Crossover at the LaAlO$_3$/KTaO$_3$ (111) Interface

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Long Cheng, Junkun Zha, Fei Ye, Xiaofang Zhai | Summary: In two-dimensional (2D) limit, the quantum fluctuation is significantly enhanced which could induce a quantum phase transition. Investigating the quantum criticality is an effective approach to elucidate the underlying physics of 2D superconductivity. Here we […]

Dynamic strain sensing using Doppler-shift-immune phase-sensitive OFDR with ultra-weak reflection array and frequency-tracking

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 […]

The Atacama Cosmology Telescope: A measurement of galaxy cluster temperatures through relativistic corrections to the thermal Sunyaev-Zeldovich effect

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 […]

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 […]
