The main goal of the MASTER-Net project is to produce a unique fast sky survey with all sky observed over a single night down to a limiting magnitude of 21...
MELCHIORS. The Mercator Library of High Resolution Stellar Spectroscopy
Aims: Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a...
Multiwavelength Study of two Unidentified γ-ray Sources
Most counterparts of the identified low-latitude γ-ray sources are isolated neutron stars (INSs). Since INSs are characterized by an extremely high value of f X...
New Hubble Space Telescope WFC3/UVIS Observations Augment the Stellar-population Complexity of ω Centauri
We used archival multi-band Hubble Space Telescope observations obtained with the Wide Field Camera 3 in the UV-optical channel to present important new...
We have compiled a catalogue of light curve solutions of contact binary stars. It contains the results of 159 light curve solutions. The properties of contact...
Opening PANDORA's box: APEX observations of CO in PNe
Context. Observations of molecular gas have played a key role in developing the current understanding of the late stages of stellar evolution. Aims: The survey...
Optical and Infrared Counterparts of the X-Ray Sources Detected in the Chandra Cygnus OB2 Legacy Survey
The young massive OB association Cygnus OB2, in the Cygnus X complex, is the closest (~1400 pc) star-forming region to the Sun hosting thousands of young low...
Optical Photometric GTC/OSIRIS Observations of the Young Massive Association Cygnus OB2
In order to fully understand the gravitational collapse of molecular clouds, the star formation process, and the evolution of circumstellar disks, these...
Optical validation and characterisation of Planck PSZ1 sources at the Canary Islands observatories. II. Second year of ITP13 observations
We report new galaxy clusters previously unknown included in the first Planck Sunyaev-Zeldovich (SZ) sources catalogue, the PSZ1. The results presented here...
