Filiation et novum temporel : le cas d’Interstellar et d’Arrival
Interstellar (Christopher Nolan, 2014) and Arrival (Denis Villeneuve, 2016) each offer a remarkable example of the tension between the affective charge proper to character development – affection, dilemma, sacrifice – and the cognitive distancing proper ...

The Turbulent Interstellar Medium [PDF]
An overview is presented of the main properties of the interstellar medium. Evidence is summarized that the interstellar medium is highly turbulent, driven on different length scales by various energetic processes.

Metallicity Dependence of Molecular Cloud Hierarchical Structure at Early Evolutionary Stages
The formation of molecular clouds out of H i gas is the first step toward star formation. Its metallicity dependence plays a key role in determining star formation throughout cosmic history.

Acceleration of dust particles by low-frequency Alfv\'en waves [PDF]
We investigate the efficiency of acceleration of charged dust particles by low-frequency Alfv\'en waves in nonlinear approximation. We show that the longitudinal acceleration of dust particles is proportional to the square of the soliton amplitude $O ...

New solar modulation modeling of the galactic proton flux measured by the AMS02 and PAMELA experiments [PDF]
A thorough understanding of solar effects on the galactic cosmic rays is relevant both to infer the local interstellar spectrum characteristics and to investigate the dynamics of charged particles in the heliosphere.

Dynamical charging of interstellar dust particles in the heliosphere
Interstellar dust (ISD) particles penetrate the solar system due to the relative motion of the Sun and the local interstellar cloud. Before entering the heliosphere, they pass through the heliospheric interface - the region of the solar wind interaction with the interstellar plasma.

PAH under XUV excitation: an ultrafast XUV-photochemistry experiment for astrophysics [PDF]
Understanding processes induced by XUV excitation of Polycyclic Aromatic Hydrocarbons (PAHs) is at the heart of molecular astrophysics, which aims at understanding molecular evolution in interstellar media. We used ultrashort XUV pulses to produce highly
