A new population of terrestrial gamma-ray flashes in the RHESSI data
(Peer reviewed; Journal article, 2015-12-23)Terrestrial gamma-ray flashes (TGFs) are the most energetic photon phenomenon occurring naturally on Earth. An outstanding question is as follows: Are these flashes just a rare exotic phenomenon or are they an intrinsic ... -
Nonlinear echoes from encapsulated antibubbles
(Peer reviewed; Journal article, 2015-09-19)An antibubble consists of a liquid droplet, surrounded by a gas, often with an encapsulating shell. Antibubbles of microscopic sizes suspended in fluids are acoustically active in the ultrasonic range. Antibubbles have ... -
