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...
Optical validation and characterization of Planck PSZ1 sources at the Canary Islands observatories. I. First year of ITP13 observations
We have identified new clusters and characterized previously unknown Planck Sunyaev-Zeldovich (SZ) sources from the first Planck catalogue of SZ sources (PSZ1)...
Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. I. First year of LP15 observations
Aims: The second catalogue of Planck Sunyaev-Zeldovich (SZ) sources, hereafter PSZ2, is the largest sample of galaxy clusters selected through their SZ...
Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. II. Second year of LP15 observations
Context. The second legacy catalog of Planck Sunyaev-Zeldovich (SZ) sources, hereafter PSZ2, provides the largest galaxy cluster sample selected by means of the...
OSIRIS deep Imaging of Cygnus OB2: the stellar population of the Cygnus X central engine
The young massive cluster Cyg OB2 is the closest massive star forming region to the Sun, with hundreds of OB members, and then the best target in the Milky Way...
