e-ASTROGAM: a space mission for MeV-GeV gamma-ray astrophysics
Journal of Physics: Conference Series, 2019 e-ASTROGAM is an observatory space mission dedicated to the study of the gamma radiation in the range from 0.3 MeV to 3 GeV. The detector is composed by a Silicon tracker, a calorimeter, and an anticoincidence system.

Publications of the Astronomical Society of the Pacific, 1993 1992 was an astrophysically exciting year for most of us. E-mail lines buzzed with news of the COBE anistropy, the Gallex solar-neutrino flux, a pulsar with two planets, and the remarkable isotropy of the gamma ray burst sources seen by CGRO. Meanwhile, more routine work continued on problems like star formation that have been around for decades and ...

Electron Density Structure Measurements With Scattered Intense Laser Beam
Contributions to Plasma Physics, EarlyView.ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.

Predicting the Uniform Electron Gas Stopping Power at Moderate and Strong Coupling
Contributions to Plasma Physics, EarlyView.ABSTRACT This paper presents a detailed study of the stopping power of a homogeneous electron gas in moderate and strong coupling regimes using the self‐consistent version of the method of moments as the key theoretical approach capable of expressing the dynamic characteristics of the system in terms of the static ones, which are the moments.

On Nearly Newtonian Potentials and Their Implications to Astrophysics
Galaxies, 2018 We review the concept of the slow motion problem in General relativity. We discuss how the understanding of this process may imprint influence on the explanation of astrophysical ...

Publications of the Astronomical Society of the Pacific, 1992 Science, notoriously, progresses amoeba-like, thrusting out pseudopods in unpredictable directions and dragging in the rest of the body after or, occasionally, retreating in disorder. This review attempts to shine a narrow and not unprejudiced beam of light on areas of astrophysics where the author believes that something interesting happened in 1991 ...

Contributions to Plasma Physics, EarlyView.ABSTRACT Experiments of isochoric heating by protons of solid material were recently performed at LULI laser facilities. In these experiments, protons, produced from target normal sheath acceleration (TNSA) of Au foil with the PICO2000 laser, deposit their energy into an aluminum or copper foil initially at room temperature and solid density.

Dark Matter in Modern Cosmology
, 2010 The presence of Dark Matter (DM) is required in the universe regulated by the standard general relativistic theory of gravitation. The nature of DM is however still elusive to any experimental search.

The Vlasov Equation Cannot Fully Account for Collisionless Shocks
Contributions to Plasma Physics, EarlyView.ABSTRACT It is argued that the Vlasov equation cannot fully account for collisionless shocks since it conserves entropy, while a shock does not. A rigorous mathematical theory of collisionless shocks could require working at the Klimontovich level.
