Abstract: In this paper, we study the 10 traveling ionospheric disturbances (TIDs) observed at zobsā¼283 km by the TIDDBIT ionospheric sounder on 30 October 2007 at 0400-0700 UT near Wallops Island, USA. These TIDs propagated northwest/northward,… read more here.

Abstract: The development of hydrodynamic instabilities has a significant impact on the operation of laser fusion systems. During radiation compression, the shells of a target are accelerated, resulting in the growth of perturbations at their interfaces.… read more here.

DOI: 10.1088/1475-7516/2021/07/046
Abstract: We calculate the gravitational wave background produced from density perturbations in an early matter domination era where primordial black holes form. The formation of black holes requires perturbations out of the linear regime. Space with… read more here.
