We observed the reflection nebula NGC 7023 at various positions using wide and narrow band photometry centred on the 7.7 and 11.3μm PAH emission features and...
Very-high-energy gamma-ray observations of the Type Ia Supernova SN 2014J with the MAGIC telescopes
Context. In this work we present data from observations with the MAGIC telescopes of SN 2014J detected on January 21 2014, the closest Type Ia supernova since...
VGCF detection of galaxy systems at intermediate redshifts
We continue the development of our Voronoi Galaxy Cluster Finder (VGCF) technique by applying it to galaxy catalogs obtained with B and R band observations of...
VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
Context. QSO B1420+326 is a blazar classified as a flat-spectrum radio quasar (FSRQ). At the beginning of the year 2020, it was found to be in an enhanced flux...
VIMOS integral field spectroscopy of blue compact galaxies. I. Morphological properties, diagnostic emission-line ratios, and kinematics
Context. Blue compact galaxies (BCG) are gas-rich, low-luminosity, low-metallicity systems that undergo a violent burst of star formation. These galaxies offer...

Context. Near-Earth asteroid 2012 DA14 made its closest approach on February 15, 2013, when it passed at a distance of 27 700 km from the Earth's surface. It...
Visible spectroscopy in the neighborhood of 2003EL{61}
Context: The recent discovery of a group of trans-neptunian objects (TNOs) in a narrow region of the orbital parameter space and with surfaces composed of...
Visible spectroscopy of 2003 UB313: evidence for N2 ice on the surface of the largest TNO?
Context: .The recent discovery of two large trans-Neptunian objects (TNOs) 2003 UB313 and 2005 FY9, with surface properties similar to those of Pluto, provides...
Visible spectroscopy of the Sulamitis and Clarissa primitive families: a possible link to Erigone and Polana
The low-inclination (i 8∘) primitive asteroid families in the inner main belt, that is, Polana-Eulalia, Erigone, Sulamitis, and Clarissa, are considered to be...
