Non thermal emission from microquasar/ISM interaction
P. Bordas, V. Bosch-Ramon, J. M. Paredes +1
The interaction of microquasar jets with their environment can produce non-thermal radiation as is the case for extragalactic outflows impacting on their surroundings. We have deve…
Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54
P. Reig, J. M Torrejon, I. Negueruela +3
The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in the time range 0.001-1000 s.…

The Agile Collaboration, Webt Collaboration, Magic Collaboration +2
We present optical, X-ray, high energy ( GeV) and very high energy ( GeV; VHE) observations of the high-frequency peaked blazar Mrk 421 taken betwee…
Exploring the powering source of the TeV X-ray binary LS 5039
J. Moldon, M. Ribo, Josep M. Paredes +2
LS 5039 is one of the four TeV emitting X-ray binaries detected up to now. The powering source of its multi-wavelength emission can be accretion in a microquasar scenario or wind i…
Improving the performance of the single-dish Cherenkov telescope MAGIC through the use of signal timing
MAGIC Collaboration
The Cherenkov light flashes produced by Extensive Air Showers are very short in time. A high bandwidth and fast digitizing readout, therefore, can minimize the influence of the bac…
First detection of glycolaldehyde outside the Galactic Center
M. T. Beltran, C. Codella, S. Viti +2
Glycolaldehyde is the simplest of the monosaccharide sugars and is directly linked to the origin of life. We report on the detection of glycolaldehyde (CH2OHCHO) towards the hot mo…
Using ages and kinematic traceback: the origin of young local associations
D. Fernandez, F. Figueras, J. Torra
Over the last decade, several groups of young (mainly low-mass) stars have been discovered in the solar neighbourhood (closer than ~100 pc), thanks to cross-correlation between X-r…
The L723 low mass star forming protostellar system: resolving a double core
J. M. Girart, R. Rao, R. Estalella
We present 1.35 mm SMA observations around the low-mass Class 0 source IRAS 19156+1906, at the the center of the L723 dark cloud. We detected emission from dust as well as emission…
MAGIC upper limits to the VHE gamma-ray flux of 3C454.3 in high emission state
H. Anderhub, S. Vercellone, I. Donnarumma +2
We report upper limits to the very high energy flux (E>100 GeV) of the flat spectrum radio quasar 3C454.3 (z=0.859) derived by the Cherenkov telescope MAGIC during the high states…
A radio and near-infrared mini-survey of the MGRO J2019+37 complex
J. M. Paredes, J. Marti, C. H. Ishwara-Chandra +9
MGRO J2019+37 is an unidentified source of very high energy gamma-rays originally reported by the MILAGRO collaboration as the brightest TeV source in the Cygnus region. Despite th…
The BAST algorithm for transit detection
S. Renner, H. Rauer, A. Erikson +4
The pioneer space mission for photometric exoplanet searches, CoRoT, steadily monitors about 12000 stars in each of its fields of view. Transit detection algorithms are applied to…
Gamma rays from compact binary system
Josep M. Paredes
Some of the very high energy (VHE) gamma-ray sources detected with the modern generation of Cherenkov telescopes have been identified with previously known X-ray binary systems. Th…
Absolute properties of the low-mass eclipsing binary CM Draconis
J. C. Morales, I. Ribas, C. Jordi +12
Spectroscopic and eclipsing binary systems offer the best means for determining accurate physical properties of stars, including their masses and radii. The data available for low-…
On the radiative efficiencies, Eddington ratios, and duty cycles of luminous high-redshift quasars
Francesco Shankar, Martin Crocce, Jordi Miralda-Escude' +2
We investigate the characteristic radiative efficiency ε, Eddington ratio λ, and duty cycle P_0 of high-redshift active galactic nuclei (AGN), drawing on measurements of the AGN lu…
Discovery of a very high energy gamma-ray signal from the 3C 66A/B region
MAGIC Collaboration, E. Aliu
The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…
Upper Limits on the VHE gamma-ray Emission from the Willman 1 Satellite Galaxy with the MAGIC telescope
MAGIC Collaboration, E. Aliu
We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May 2008. No significant…
Integral Field Spectroscopy of HH 262: The Spectral Atlas
R. Lopez, B. Garcia-Lorenzo, S. F. Sanchez +3
HH 262 is a group of emitting knots displaying an "hour-glass" morphology in the Halpha and [SII] lines, located 3.5' to the northeast of the young stellar object L1551-IRS5, in Ta…
A collimated, ionized bipolar structure and a high density torus in the young planetary nebula IRAS 17347-3139
