Direct Measurement of Electron Heating in Electron-Only Reconnection in a Laboratory Mini-Magnetosphere
We report on the experimental observation of electron heating in electron-only magnetic reconnection in laser-driven laboratory mini-magnetospheres on the Large Plasma Device (LAPD) at the University of California, Los Angeles. In this experiment, a fast-flowing plasma impacts a pulsed magnetic dipole embedded within LAPD's magnetized ambient plasma, creating an ion-scale magnetosphere and driving electron-only magnetic reconnection between the background and dipole field lines. The electron ve…

Off to Detroi to see Deltron 3030 at the Majestic!
We’re checked into the Ferry St. Inn, in this stately old mansion, one of four tucked behind the DIA. We’re in the maid’s quarters, a third story walk up. We’ve stayed here before.

Lepton Collider as a Window to Reheating via Freezing Out Dark Matter Detection
We investigate a particle dark matter (DM) scenario where the DM interaction with the Standard Model are mediated by a leptophilic effective operator. Unlike conventional WIMP scenarios where thermal freeze-out occurs in a radiation-dominated Universe, we consider DM freeze-out during a prolonged reheating epoch driven by inflaton decay. The resulting departure from standard cosmology alters the thermal evolution of the dark matter abundance, making it sensitive to the reheating temperature and…
