We present the first photometric analysis of the supernova (SN) impostor AT 2016blu in NGC
4559. This transient was discovered by the Lick Observatory Supernova Search in 2012 and …

Context. The Carina Nebula is one of the major massive star-forming regions in the Galaxy.
Its relatively nearby distance (2.35 kpc) makes it an ideal laboratory for the study of massive …

The binary stellar system η Carinae is one of very few established astrophysical hadron
accelerators. It seems likely that at least some fraction of the particles accelerated by η …

ABSTRACT η Carinae is an extremely luminous and energetic colliding-wind binary. The
combination of its orbit and orientation, with respect to our line of sight, enables direct …

Colliding winds of massive stars in binary systems (CWB) have been proposed as potential
sites of relativistic cosmic-ray acceleration and non-thermal very-high-energy (VHE) photons …

Only a few gamma-ray sources have been established as proton accelerators over the last
decades, among them two extraordinary binary systems, the massive colliding wind binary …
