Colliding red giants in galactic nuclei: Shocks, jets, impact on the ISM, X- and gamma-rays, neutrinos, fusion ignition and afterglow

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, , , , | Summary: In galactic nuclei, stellar densities are so high that stars can physically collide with each other. In this work we focus on the collision of red giants and in particular on the formation of non-thermal processes through collisions […]

Enabling Kilonova Science with Nancy Grace Roman Space Telescope

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Igor Andreoni, Michael W. Coughlin, Alexander W. Criswell, Mattia Bulla, Andrew Toivonen | Summary: Binary neutron star mergers and neutron star-black hole mergers are multi-messenger sources that can be detected in gravitational waves and in electromagnetic radiation. The low electron fraction of neutron star merger ejecta […]

A fast radio burst localized at detection to a galactic disk using very long baseline interferometry

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Tomas Cassanelli, Calvin Leung, Pranav Sanghavi, Juan Mena-Parra, Savannah Cary | Summary: Fast radio bursts (FRBs) are millisecond-duration, luminous radio transients of extragalactic origin. These events have been used to trace the baryonic structure of the Universe using their dispersion measure (DM) assuming that the contribution […]

The Classical Equations of Motion of Quantized Gauge Theories, Part 2: Electromagnetism

Kavli Affiliate: Tom Melia | First 5 Authors: David E. Kaplan, Tom Melia, Surjeet Rajendran, , | Summary: In this and companion papers, we show that quantum field theories with gauge symmetries permit a broader class of classical dynamics than typically assumed. In this article, we show that the quantization of electromagnetism permits the existence […]

Giant anisotropic band flattening in twisted $Γ$ valley semiconductor bilayers

Kavli Affiliate: Jing Wang | First 5 Authors: Huan Wang, Zhaochen Liu, Yadong Jiang, Jing Wang, | Summary: We propose a theory of anisotropic band flattening in moir’e systems at the $Gamma$ valley. We find that in twisted anisotropic two-dimensional crystals with a rectangular unit cell of $C_{2z}$ or mirror symmetries, a larger effective mass […]
