Data reduction procedures aim to minimize the impact of data acquisition imperfections on the measurement of data properties with a scientific meaning for the astronomer. To achieve this purpose, appropriate arithmetical manipulations with data and calibration frames must be performed. Furthermore, a full understanding of all the possible

As a part of our collaboration in the COSMOS Project, devoted to the characterization of galaxies during the epoch of maximum star formation in the history of the Universe, we have carried out a deep photometric survey covering about 380 arcmin2 in the so-called Groth Strip Flanking Fields. The observations were obtained in the K' band with the

The evaluation of the use of library collections is a fundamental tool for the development of a relevant and cost-effective collection. Bibliometrics offers several methods to measure the level of use of collections. In this paper, we present the first results of a bibliometric analysis of the references cited in the articles published by authors

A new part of our long term study of IR mergers and IR QSOs with galactic winds (GW) is reported. In particular, we present a study of morphology, kinematic and ionization structure of: Arp 220, Mrk 231 and NGC 4038/39. This program is based mainly on INTEGRAL two dimensional (2D) spectroscopy obtained on the 4.2 m William Herschel Telescope (at La
