Supernovae in colliding-wind binaries: observational signatures in the first year
Ondřej Pejcha, Diego Calderón, Petr Kurfürst
When a core-collapse supernova explodes in a binary star system, the ejecta might encounter an overdense shell, where the stellar winds of the two stars previously collided. In thi…
VLA Radio Study of a Sample of Nearby X-ray and Optically Bright Early-Type Galaxies
Romana Grossová, Norbert Werner, Francesco Massaro +9
Many massive early-type galaxies host central radio sources and hot X-ray atmospheres indicating the presence of radio-mechanical active galactic nucleus (AGN) feedback. The duty c…
Electromagnetic signatures of strong-field gravity from accreting black holes
Vladimir Karas, Michal Zajacek, Devaky Kunneriath +1
Observations of galactic nuclei help us to test General Relativity. Whereas the No-hair Theorem states that classical, isolated black holes eventually settle to a stationary state…
A shock near the virial radius of the Perseus Cluster
Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu +6
Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperatu…
