Dual electro-optic frequency comb photonic thermometry

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Adam J. Fleisher, Zeeshan Ahmed, Tobias Herman, Matthew R. Hartings, | Summary: We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a $pi$-phase-shifted fiber Bragg grating. We achieve read-out stability of 7.5 mK at 1 s and resolve temperature changes of similar magnitude–sufficient […]

Nostradamus: Weathering Worth

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Alapan Chaudhuri, Zeeshan Ahmed, Ashwin Rao, Shivansh Subramanian, Shreyas Pradhan | Summary: Nostradamus, inspired by the French astrologer and reputed seer, is a detailed study exploring relations between environmental factors and changes in the stock market. In this paper, we analyze associative correlation and causation between environmental […]

THESAN-HR: How does reionization impact early galaxy evolution?

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Josh Borrow, Rahul Kannan, Enrico Garaldi, Aaron Smith, Mark Vogelsberger | Summary: Early galaxies were the radiation source for reionization, with the photoheating feedback from the reionization process expected to reduce the efficiency of star formation in low mass haloes. Hence, to fully understand reionization and galaxy […]

A General Framework for Removing Point Spread Function Additive Systematics in Cosmological Weak Lensing Analysis

Kavli Affiliate: Masahiro Takada | First 5 Authors: Tianqing Zhang, Xiangchong Li, Roohi Dalal, Rachel Mandelbaum, Michael A. Strauss | Summary: Cosmological weak lensing measurements rely on a precise measurement of the shear two-point correlation function (2PCF) along with a deep understanding of systematics that affect it. In this work, we demonstrate a general framework […]

Search for an invisible $Z^prime$ in a final state with two muons and missing energy at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed | Summary: The $L_{mu}-L_{tau}$ extension of the standard model predicts the existence of a lepton-flavor-universality-violating $Z^{prime}$ boson that couples only to the heavier lepton families. We search for such a $Z^prime$ through its invisible decay in […]

Effects of the interplay between fermionic interactions and disorders in the nodal-line superconductors

Kavli Affiliate: Jing Wang | First 5 Authors: Wen-Hao Bian, Xiao-Zhuo Chu, Jing Wang, , | Summary: We study the interplay between fermion-fermion interactions and disorder scatterings beneath the superconducting dome of noncentrosymmetric nodal-line superconductors. With the application of renormalization group, several interesting low-energy behaviors are extracted from the coupled equations of all interaction parameters. […]

A New Component from the Quiet Sun: Synchrotron Radiation from Galactic Cosmic-Ray Electrons

Kavli Affiliate: Vahe Petrosian | First 5 Authors: , , , , | Summary: The quiet Sun, i.e. in its non-flaring state or non-flaring regions, emits thermal radiation from radio to ultraviolet. The quiet Sun produces also non-thermal radiation observed in gamma rays due to interactions of Galactic Cosmic Rays (GCR) with the solar gas […]

Transport of Cosmic ray electrons from 1 AU to the Sun

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Vahe’ Petrosian, Elena Orlando, Andrew Strong, , | Summary: Gamma rays are produced by cosmic ray (CR) protons interacting with the particles at solar photosphere and by cosmic ray electrons and positrons (CRes) via inverse Compton scattering of solar photons. The former come from the solar disk […]
