Twofitlines is a tool developed within IRAF, optimized to be used with data containing multiple spectra along the spatial axis of the detector. A given spectral...
Type 2 AGN in the Local Universe: Two New Invariances?
Starting from a sample of type-2 AGN, the effect of the large-scale environmental density (LSED, parametrized by the surface density) on the mass of central...
Ubiquitous Horizontal Magnetic Fields in the Quiet Solar Photosphere as Revealed by HINODE Meaurements
Measurements with the HINODE Spectro-Polarimeter (SP) of the quiet Sun allow characterization of the weak, mixed-polarity magnetic flux at the highest angular...
UBVI light curves of NGC 884 variables (Saesen+, 2010)
We present here the light curves in the four filters of the 184 detected variable stars in NGC 884. These variable stars are listed in tables 3 and A.1 of the...
UBVI Time-series Photometry of the Old LMC Globular Cluster Reticulum
We present new UBVI CCD observations of the old LMC globular cluster RETICULUM. These data allowed us to re-determine periods and light curves and to identify 4...
UBVR photometry of the open cluster King 2 (Aparicio+ 1990)
In this paper we present the Johnson-Cousins UBVR CCD photometry of the stars in King 2, an old open cluster towards the galactic anticenter. We have obtained...
