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 […]
