Why the northern hemisphere needs a 30-40 m telescope and the science at stake: Massive stars in spiral galaxies
J. Maíz Apellániz, S. Simón-Díaz, A. Herrero +5
This document discusses the three main lines expected to dominate massive-star research in the 2040s, namely: (1) The role of metallicity in stellar evolution, especially in determ…
Science Enabled by a 30-Meter-Class Telescope in the Northern Hemisphere: Massive Stars at Low Metallicity
Miriam Garcia, Artemio Herrero, Ignacio Negueruela +11
Massive stars are at the core of our observations of the Universe up to the reionization epoch, both through their intense ionizing fluxes and through the energetic end products th…
A new reference catalogue for the very metal-poor Universe: +150 OB stars in Sextans A
Marta Lorenzo, Miriam Garcia, Francisco Najarro +3
Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early galaxies. These stars may…
Near-infrared study of the stellar population of Sh2-152
S. Ramírez Alegría, A. Herrero, A. Marín-Franch +5
Context: The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has changed our view of…
New Optical Results on gamma-ray Binaries
J. Casares, J. M. Corral-Santana, A. Herrero +9
We present new optical spectroscopy of the gamma-ray binary LS 5039. Our data show evidence for sub-orbital modulation in the radial velocities with amplitude ~7 km/s and period ~P…
The VLT-FLAMES Tarantula Survey
C. J. Evans, N. Bastian, Y. Beletsky +28
The Tarantula Survey is an ambitious ESO Large Programme that has obtained multi-epoch spectroscopy of over 1,000 massive stars in the 30 Doradus region of the Large Magellanic Clo…
Suzaku and Multi-wavelength Observations of OJ 287 during the Periodic Optical Outburst in 2007
Hiromi Seta, Naoki Isobe, Makoto S. Tashiro +10
Suzaku observations of the blazar OJ 287 were performed in 2007 April 10--13 and November 7--9. They correspond to a quiescent and a flaring state, respectively. The X-ray spectra…
The stellar population of the star forming region G61.48+0.09
A. Marin-Franch, A. Herrero, A. Lenorzer +4
- Context: We present the results of a near-infrared photometric and spectroscopic study of the star forming region G61.48+0.09. - Aims: The purpose of this study is to characteriz…
Discovery of VHE Gamma Radiation from IC443 with the MAGIC Telescope
MAGIC Collaboration
We report the detection of a new source of very high energy (VHE, E_gamma >= 100GeV) gamma-ray emission located close to the Galactic Plane, MAGIC J0616+225, which is spatially coi…
