An attempt is made to find the zodiacal cloud shape out of the ecliptic, on the basis of the Mujica et al (1980) establishment of the optical homogeneity of the...

We have carried out a continuous multiband photometric monitoring of the nuclear activity of comet 29P/Schwassmann-Wachmann 1 from 2008 to 2010. Our main aim...

We present high resolution spectroscopy of the common proper motion system FH Leo (components HD 96273 and BD+07 2411B), which has been classified as a novalike...

Driven by the incomplete understanding of the formation of gas giant extrasolar planets and of their mass-radius relationship, several ground-based, wide-field...

Using deep photometric data from Wide Field Camera at the Isaac Newton Telescope and Wide Field Imager at the ESO 2.2-m telescope we measure the outer number...

We present deep optical imaging of three face-on disk galaxies together with a detailed description of the reduction and calibration methods used, in order to...

As part of an extensive study of the physical properties of active galactic nuclei (AGNs) we report high spatial resolution near-IR integral-field spectroscopy...
