Cherenkov Telescope Array Contributions to the 35th International Cosmic Ray Conference (ICRC2017)
F. Acero, B. S. Acharya, V. Acín Portella +1137
List of contributions from the Cherenkov Telescope Array Consortium presented at the 35th International Cosmic Ray Conference, July 12-20 2017, Busan, Korea.
The IACOB project: III. New observational clues to understand macroturbulent broadening in massive O- and B-type stars
S. Simón-Díaz, M. Godart, N. Castro +5
We aim to provide new empirical clues about macroturbulent spectral line broadening in O- and B-type stars to evaluate its physical origin. We use high-resolution spectra of ~430 s…
On the formation and evolution of the first Be star in a black hole binary MWC 656
M. Grudzinska, K. Belczynski, J. Casares +8
We find that the formation of MWC 656 (the first Be binary containing a black hole) involves a common envelope phase and a supernova explosion. This result supports the idea that a…
Optimized dark matter searches in deep observations of Segue 1 with MAGIC
J. Aleksić, S. Ansoldi, L. A. Antonelli +156
We present the results of stereoscopic observations of the satellite galaxy Segue 1 with the MAGIC Telescopes, carried out between 2011 and 2013. With almost 160 hours of good-qual…
Observations of VHE gamma-ray binaries with the MAGIC Telescopes
A. López-Oramas, O. Blanch Bigas, J. Cortina +10
Several binary systems, composed of a star and a compact object, have been detected in the GeV-TeV range. Several systems have been observed but only a handful of sources have show…
CTA contributions to the 33rd International Cosmic Ray Conference (ICRC2013)
The CTA Consortium, :, O. Abril +1102
Compilation of CTA contributions to the proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), which took place in 2-9 July, 2013, in Rio de Janeiro, Brazil
Macroturbulent broadening: a single snap-shot approach to investigate pulsations in massive stars?
S. Simón-Díaz, N. Castro, A. Herrero +3
We present a brief progress report of our project aimed at the investigation of the so-called macroturbulent broadening affecting the line-profiles of O and early B-type stars, and…
Spectroscopic and physical parameters of Galactic O-type stars. I. Effects of rotation and spectral resolving power in the spectral classification of dwarfs and giants
N. Markova, J. Puls, S. Scuderi +2
The modern-era spectral classification of O-stars relies on either the Walborn or the Conti-Mathys scheme. Since both of these approaches have been developed using low-quality phot…
Observational evidence for a correlation between macroturbulent broadening and line-profile variations in OB Supergiants
S. Simón-Díaz, A. Herrero, K. Uytterhoeven +3
The spectra of O and B supergiants are known to be affected by a significant form of extra line broadening (usually referred to as macroturbulence) in addition to that produced by…
Design Concepts for the Cherenkov Telescope Array
The CTA Consortium
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…
Is macroturbulent broadening in OB Supergiants related to pulsations?
S. Simón-Díaz, K. Uytterhoeven, A. Herrero +3
The spectrum of O and B Supergiants is known to be affected by an important extra line-broadening (usually called macroturbulence) that adds to stellar rotation. Recent analysis of…

A possible black hole in the gamma-ray microquasar LS 5039
J. Casares, M. Ribo, I. Ribas +3
The population of high energy and very high energy gamma-ray sources, detected with EGRET and the new generation of ground-based Cherenkov telescopes, conforms a reduced but physic…
