We present a detailed analysis of the radial distribution of dust properties (extinction, PAH abundance and dust-to-gas ratio) in 57 galaxies in the SINGS sample, performed on a multi-wavelength set of UV, IR and radio surface brightness profiles, combined with published molecular gas profiles and metallicity gradients.

We describe the OTELO survey and present deep BVRI imaging data of the Groth field. Galaxy number counts and galaxy clustering are analyzed. We find an excellent agreement between observed and mock data number counts. We also find a evidences about a galaxy clustering evolution and a strong dependence of the angular correlation function with the

We calculated new estimates of the Delta VHBbump parameter for 15 Galactic Globular Clusters (GGCs) using accurate ground-based photometric data. We enlarged our sample with literature data and we obtained a sample of 62 GGCs covering a wide metallicity range (-2.16le [M/H]le -0.58 dex). To compare the data with the theory we used theoretical

The MAGIC Observatory is one of the main instruments in the northern hemisphere for mea-suring gamma rays from celestial objects in the very high energy regime. It consists of two 17m diameter IACTs (Imaging Atmospheric Cherenkov Telescopes) with a baseline of 85m sited at 2200 m.a.s.l. on Roque de los Muchachos (European Northern Observatory, La

We present a coordinated study of the complex star forming region NGC 6334 including a wide range of observations from radio to X-ray.
