After initial claims and a long hiatus, it is now established that several binary stars emit high-
(0.1–100 GeV) and very high-energy (> 100 GeV) gamma rays. A new class has emerged …

Starforming factories in galaxies produce compact clusters and loose associations of young
massive stars. Fast radiation-driven winds and supernovae input their huge kinetic power …

This paper presents a catalog of high-energy γ-ray sources detected in the first two years of
the Fermi Gamma-ray Space Telescope mission by the Large Area Telescope (LAT). It is the …

This catalog summarizes 117 high-confidence⩾ 0. 1 GeV gamma-ray pulsar detections
using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite …

Context. Young massive stellar clusters are extreme environments and potentially provide
the means for efficient particle acceleration. Indeed, they are increasingly considered as …

Massive systems made of two or more stars are known to be the site for interesting physical
processes–including at least in some cases–particle acceleration. Over the past decade, this …

We present the first catalog of high-confidence γ-ray sources detected by the AGILE satellite
during observations performed from July 9, 2007 to June 30, 2008. Cataloged sources were …

Three-dimensional adaptive mesh refinement hydrodynamical simulations of the wind–wind
collision between the enigmatic supermassive star η Car and its mysterious companion star …

Cosmic-ray acceleration has been a long-standing mystery, and, despite more than a
century of study, we still do not have a complete census of acceleration mechanisms. The …

ABSTRACT The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space
Telescope detected a γ-ray source that is spatially consistent with the location of Eta …
