QUEST1 constructed a 16-chip CCD camera to be used on the 1m Schmidt telescope at the Llano del Hato National Astronomical Observatory in Venezuela. Normally operated in the drift-scan mode, an equatorial scan will expose any point on the sky for 143s and result in limiting magnitudes of B=18.5, V=19.2, and R=19.5 at S/N=10. These data were

In this paper, we present Q-U-I JOint Tenerife Experiment (QUIJOTE) 10-20 GHz observations (194 h in total over ≈250 deg2) in intensity and polarisation of G159.6-18.5, one of the most widely studied regions harbouring anomalous microwave emission (AME). By combining with other publicly available intensity data, we achieve the most precise spectrum

Multi-object spectroscopic observations of A115 were carried out at the TNG telescope in December 2003 during the program of proposal AOT8/CAT-G6. (1 data file).

We present a set of face-on models of the radiative transfer of stellar light in exponential discs, taking into account absorption and multiple scattering (diffusion) by dust. Attention has been directed towards the effects on the observable photometric properties of different distributions of stars and dust perpendicular to the galactic plane. A

We propose to detect and resolve the candidate radio counterpart of an ultraluminous X-ray source (ULX) at the outskirts of NGC 1313. This ULX is surrounded by a huge ionized nebula. We expect to find a corresponding synchrotron radio bubble, possibly inflated by a jet from the black hole, with additional core emission. By combining radio, optical
