The spiral structure of the Galaxy revealed by CS sources and evidence for the 4:1 resonance
J. R. D. Lepine, A. Roman-Lopes, Zulema Abraham +2
We present a map of the spiral structure of the Galaxy, as traced by molecular CS emission associated with IRAS sources which are believed to be compact HII regions. The CS line ve…
Particle Acceleration and Magnetic Field Structure in PKS 2155-304: Optical Polarimetric Observations
U. Barres de Almeida, M. J. Ward, T. P. Dominici +5
In this paper we present multiband optical polarimetric observations of the VHE blazar PKS 2155-304 made simultaneously with a H.E.S.S./Fermi high-energy campaign in 2008, when the…
Precessing jets and X-ray bubbles from NGC1275 (3C84) in the Perseus galaxy cluster: a view from 3D numerical simulations
D. Falceta-Goncalves, A. Caproni, Z. Abraham +2
The Perseus galaxy cluster is known to present multiple and misaligned pairs of cavities seen in X-rays, as well as twisted kiloparsec-scale jets at radio wavelengths; both morphol…
