First Observations of Solar Halo Gamma Rays Over a Full Solar Cycle
Tim Linden, Jung-Tsung Li, Bei Zhou +4
We analyze 15 years of Fermi-LAT data and produce a detailed model of the Sun's inverse-Compton scattering emission (solar halo), which is powered by interactions between ambient c…
Angular Distribution of Gamma Rays Produced in Proton-Proton Collisions
Spencer Griffith, John F. Beacom, Jung-Tsung Li +1
Accurate modeling of how high-energy proton-proton collisions produce gamma rays through the decays of pions and other secondaries is needed to correctly interpret astrophysical ob…
Small-Scale Magnetic Fields are Critical to Shaping Solar Gamma-Ray Emission
Jung-Tsung Li, John F. Beacom, Spencer Griffith +1
The Sun is a bright gamma-ray source due to hadronic cosmic-ray interactions with solar gas. While it is known that incoming cosmic rays must generally first be reflected by solar…
Galactic Cosmic-Ray Propagation in the Inner Heliosphere: Improved Force-Field Model
Jung-Tsung Li, John F. Beacom, Annika H. G. Peter
A key goal of heliophysics is to understand how cosmic rays propagate in the solar system's complex, dynamic environment. One observable is solar modulation, i.e., how the flux and…
Dynamics of millicharged dark matter in supernova remnants
Jung-Tsung Li, Tongyan Lin
Dark matter could have a small electromagnetic charge, provided the charge-to-mass ratio is much less than that of electrons or protons. This candidate, commonly known as millichar…
Neutrino Burst-Generated Gravitational Radiation From Collapsing Supermassive Stars
Jung-Tsung Li, George M. Fuller, Chad T. Kishimoto
We estimate the gravitational radiation signature of the electron/positron annihilation-driven neutrino burst accompanying the asymmetric collapse of an initially hydrostatic, radi…
Parametrized Post-Newtonian Limit of Teleparallel Dark Energy Model
Jung-Tsung Li, Yi-Peng Wu, Chao-Qiang Geng
We study the post-Newtonian limit in the teleparallel equivalent of General Relativity with a scalar field which non-minimally couples to gravity. The metric perturbation is obtain…
Einstein Static Universe in Exponential Gravity
Jung-Tsung Li, Chung-Chi Lee, Chao-Qiang Geng
We analyze the stability of the Einstein static closed and open universe in two types of exponential gravity theories. We show that the stable solutions exist in these two m…
