We present accurate and deep multiband B,R,Hα data for the globular cluster ω Cen collected with the Advanced Camera for Surveys on HST. The photometric...
Why are Massive O-rich AGB Stars in our Galaxy not S-stars?
We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical...
Why we need to measure turbulent magnetic fields in HII regions
We have measured the emission line profiles in Hα from populations of HII regions in nearby spiral galaxies, and extracted their non-thermal line widths. These...
The authors present results of a search for wide companions to halo subdwarfs of known metallicity. They have taken CCD I-band frames in order to detect faint...
Wide FastCam: a wide field imaging camera for the TCS
The FastCam instrument, jointly developed by the IAC and the UPCT, allows, in real-time, acquisition, selection and storage of images with a resolution that...
Wide Field Observations of the Ursa Minor dSph Galaxy
Ursa Minor (UMi) is one of the closest satellites of the Milky Way (d=69 kpc). It is possibly a disrupted dSph interacting with the external Galactic halo. This...
Wide Field Optical Photometry of the Carina Dwarf Spheroidal Galaxy
We present optical photometry of the Carina Dwarf Spheroidal (dSph) Galaxy. Data have been collected with CCD mosaic cameras available at the 2.2m ESO/MPI and...
Wide Range Neutron Flux Measuring Channel for Aerospace Application
The use of classical techniques for neutron flux measurements in nuclear reactors involves the switching between several detection chains as the power grows up...
I present the status and the recent results of the QUIJOTE (Q-U-I JOint TEnerife) experiment. QUIJOTE is a project that operates from the Teide Observatory...
