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 […]

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 […]

Inferring Maps of the Sun’s Far-side Unsigned Magnetic Flux from Far-side Helioseismic Images using Machine Learning Techniques

Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Ruizhu Chen, Junwei Zhao, Shea Hess Webber, Yang Liu, J. Todd Hoeksema | Summary: Accurate modeling of the Sun’s coronal magnetic field and solar wind structures require inputs of the solar global magnetic field, including both the near and far sides, but the Sun’s far-side magnetic […]

Hierarchical Inference of the Lensing Convergence from Photometric Catalogs with Bayesian Graph Neural Networks

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Simon Birrer, Madison Ueland, Miles Cranmer, Adriano Agnello | Summary: We present a Bayesian graph neural network (BGNN) that can estimate the weak lensing convergence ($kappa$) from photometric measurements of galaxies along a given line of sight. The method is of particular interest […]
