Electric Field Conjugation with the Project 1640 coronagraph

, 2013
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to find young, self-luminous planets around nearby stars. To reach the necessary

Threshold atmospheric electric fields for initiating relativistic runaway electron avalanches: theoretical estimates and CORSIKA simulations [PDF]

Geoscientific Model Development
We examine the threshold atmospheric electric field (Eth) required to initiate a runawayavalanche in Earth's atmosphere. We compare the traditional, thirty-year-old theoretical threshold with its recently updated value and with the threshold derived from
