Detection of a 14-days atmospheric perturbation peak at Paranal associated with lunar cycles
S. Cavazzani, S. Ortolani, N. Scafetta +2
In this paper we investigate the correlation between the atmospheric perturbations at Paranal Observatory and the Chilean coast tides, which are mostly modulated by the 14-day syzy…
The Gaia-ESO Survey: Empirical determination of the precision of stellar radial velocities and projected rotation velocities
R. J. Jackson, R. D. Jeffries, J. Lewis +58
The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. A key aim is to provide precise radial velocities (RVs)…
VISTA Variables in the Vía Láctea (VVV): Halfway Status and Results
Maren Hempel, Dante Minniti, István Dékány +89
The VISTA Variables in the Vía Láctea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has a…
The VVV-SkZ pipeline: an automatic PSF-fitting photometric pipeline for the VVV survey
Francesco Mauro, Christian Moni Bidin, André-Nicolas Chené +4
We present the VVV-SkZ_pipeline, a DAOPHOT-based photometric pipeline, created to perform PSF-fitting photometry of "VISTA Variables in the Vía Láctea" (VVV) ESO Public Survey data…
Optical atmospheric extinction over Cerro Paranal
F. Patat, S. Moehler, K. O'Brien +14
Aims: The present study was conducted to determine the optical extinction curve for Cerro Paranal under typical clear-sky observing conditions, with an accuracy of 0.01 mag/airmass…
