Nonthermal electron and ion acceleration by magnetic reconnection in large laser-driven plasmas

Kavli Affiliate: Tom Abel | First 5 Authors: Samuel Totorica, Masahiro Hoshino, Tom Abel, Frederico Fiuza, | Summary: Magnetic reconnection is a fundamental plasma process that is thought to play a key role in the production of nonthermal particles associated with explosive phenomena in space physics and astrophysics. Experiments at high-energy-density facilities are starting to […]

An extended halo around an ancient dwarf galaxy

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Joshua D. Simon, Denis Erkal, Laura J. Chang | Summary: The Milky Way is surrounded by dozens of ultra-faint (< $10^5$ solar luminosities) dwarf satellite galaxies. They are the surviving remnants of the earliest galaxies, as confirmed by their ancient (~13 billion years […]

Cosmic-Ray Diffusion Suppression in Star-forming Regions Inhibits Clump Formation in Gas-rich Galaxies

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: , , , , | Summary: Observations of the $gamma$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the […]

W=0 Complex Structure Moduli Stabilization on CM-type K3 x K3 Orbifolds:—Arithmetic, Geometry and Particle Physics—

Kavli Affiliate: Taizan Watari | First 5 Authors: Keita Kanno, Taizan Watari, , , | Summary: It is an important question in string compactification whether complex structure moduli stabilization inevitably ends up with a vacuum expectation value of the superpotential < W > of the order of the Planck scale cubed. Any thoughts on volume […]
