“…The Large Magellanic Cloud (LMC) is among the best laboratories for studying various astronomical objects and their physics because of its almost face-on inclination to us (∼ 35 • ) and a well-known distance (∼ 50 kpc, Pietrzyński et al 2013). Note that many shelllike structures-supergiantshells, superbubbles, supernova remnants (SNRs), are located in the LMC and can be easily observed with very little contamination as compared to the Milky Way (e.g., Dunne et al 2001;Dawson et al 2013;Maggi et al 2016;Bozzetto 2017). Recent progress in multi-wavelength high angular resolution imaging has allowed us to study the relation between the various types of shells and their environments in the LMC.…”

We analyzed the 2.6-mm CO and 21-cm Hi lines toward the Magellanic superbubble 30 Doradus C, in order to reveal the associated molecular and atomic gas. We uncovered five molecular clouds in a velocity range from 251 to 276 km s −1 toward the western shell. The non-thermal X-rays are clearly enhanced around the molecular clouds on a pc scale, suggesting possible evidence for magnetic field amplification via shock-cloud interaction. The thermal X-rays are brighter in the eastern shell, where there are no dense molecular or atomic clouds, opposite to the western shell. The TeV γ-ray distribution may spatially match the total interstellar proton column density as well as the non-thermal X-rays. If the hadronic γ-ray is dominant, the total energy of the cosmic-ray protons is at least ∼ 1.2 × 10 50 erg with the estimated mean interstellar proton density ∼ 60 cm −3 . In addition the γ-ray flux associated with the molecular cloud (e.g., MC3) could be detected and resolved by the Cherenkov Telescope Array (CTA). This should permit CTA to probe the diffusion of cosmic-rays into the associated dense ISM.

“…Mais alors que chez More cet ailleurs merveilleux était géographique, pour la dystopie, il est situé dans le passé et il correspond à notre réalité présente. Ce qui explique qu'on ait pu juger « réactionnaire » le genre dystopique : il semble avertir de ne rien changer sous peine de catastrophe 27 .…”
