Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers
Contributions to Plasma Physics, EarlyView.ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

Hydrodynamical scaling laws for astrophysical jets [PDF]
arXiv, 2005 The idea of a unified model for all astrophysical jets has been considered for some time now. We present here some hydrodynamical scaling laws relevant for all type of astrophysical jets, analogous to those of Sams et al. (1996). We use Buckingham's Pi theorem of dimensional analysis to obtain a family of dimensional relations among the physical ...

Light, Gravity and Matter (with emphasis on thermo-gravity waves) [PDF]
INCAS BulletinWhat are light, gravity, and regenerating matter? Where do they originate and where do they go? The answers to these questions lie in one of the most powerful equations ever discovered: Euler's formula (i.e., complex analysis).

E-prints and Journal Articles in Astronomy: a Productive Co-existence
, 2006 Are the e-prints (electronic preprints) from the arXiv repository being used instead of the journal articles? In this paper we show that the e-prints have not undermined the usage of journal papers in the astrophysics community.

Astrophysics Conducted by the Lunar University Network for Astrophysics Research (LUNAR) and the Center for Lunar Origins (CLOE) [PDF]
arXiv, 2012 [Abridged] The Moon is a unique platform from and on which to conduct astrophysical measurements. The Lunar University Network for Astrophysics Research (LUNAR) and the Center for Lunar Origins and Evolution (CLOE) teams within the NASA Lunar Science Institute (NLSI) are illustrating how the Moon can be used as a platform to advance important goals in ...

Fundamental Problems in Astrophysics
Astrophysics and Space Science, 2006 Progress of modern astrophysics requires the access to the electromagnetic spectrum in the broadest energy range. The Ultraviolet is a fundamental energy domain since it is one of the most powerful tool to study plasmas at temperatures in the 3,000–300,000 K range as well as electronic transitions of the most abundant molecules in the Universe ...

AutoCal: A software application for calibrating photometric data
South African Journal of Science, 2016 We present a software application for the calibration of stellar magnitudes in the absence of standard stars. It uses an existing algorithm to match stars in the target’s field of view to catalogue entries and computes the average offset between the two ...
