Resonant W and Z Boson Production in FSRQ Jets: Implications for Diffuse Neutrino Fluxes

Ji-Hoon Ha, Ibragim Alikhanov

Blazars, particularly Flat Spectrum Radio Quasars (FSRQs), are well-known for their ability to accelerate a substantial population of electrons and positrons, as inferred from mult…

Contrast-independent partially explicit time discretizations for multiscale flow problems

Eric T. Chung, Yalchin Efendiev, Wing Tat Leung +1

Many multiscale problems have a high contrast, which is expressed as a very large ratio between the media properties. The contrast is known to introduce many challenges in the desi…
