Design concepts for the Cherenkov Telescope Array CTA: an advanced facility for ground-based high-energy gamma-ray astronomy
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has aExpand
Variable Very-High-Energy Gamma-Ray Emission from the Microquasar LS I +61 303
The detection of variable gamma-ray emission above 100 gigaelectron volts from the microquasar LS I 61 + 303 is reported, which suggests that the emission is periodic. Expand
We present results of a search for optical mi- crovariability in a selected sample of 23 southern AGNs, which includes both radio-quiet and radio-loud objects. Microvariations were clearly detectedExpand
Introducing the CTA concept
The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve theExpand
LS 5039: A runaway microquasar ejected from the galactic plane
We have compiled optical and radio astrometric data of the microquasar LS 5039 and derived its proper motion. This, together with the distance and radial velocity of the system, allows us to stateExpand
Astrophysics and Space Science manuscript No.
The COMPTEL unidentified source GRO J 1411-64 was observed by INTEGRAL and XMM-Newton in 2005. The Circinus Galaxy is the only source detected within the 4σ location error of GRO J1411-64, but inExpand
Accretion vs. colliding wind models for the gamma-ray binary LS I +61 303: an assessment
Context. LS I +61 303 is a puzzling Be/X-ray binary with variable gamma-ray emission up to TeV energies. The nature of the compact object and the origin of the high-energy emission are unclear. OneExpand
The radio to TeV orbital variability of the microquasar LS I +61 303
Context. The microquasar LS I +61 303 has recently been detected at TeV energies by the Cherenkov telescope MAGIC, presenting variability on timescales similar to its orbital period. This system hasExpand
Detection of nonthermal emission from the bow shock of a massive runaway star
Context. The environs of massive, early-type stars have been inspected in recent years in the search for sites where particles can be accelerated up to relativistic energies. Wind regions of massiveExpand
Non-thermal processes in bowshocks of runaway stars Application to ζ Ophiuchi
Context. Runaway massive stars are O- and B-type stars with high spatial velocities with respect to the interstellar medium. These stars can produce bowshocks in the surrounding gas. BowshocksExpand
