We present the stellar population analysis of a sample of 12 dwarf elliptical galaxies, observed with the SAURON integral field unit, using the full-spectrum fitting method. We show that star formation histories (SFHs) resolved into two populations can be recovered even within a limited wavelength range, provided that high signal-to-noise ratio (S

This paper presents near-infrared monitoring, taken with the 1.5 m Carlos Sanchez Telescope in Tenerife and CCD photometry taken with the Jacobus Kapteyn Telescope in La Palma, of the 1988 outburst of 3C 279. This is combined with archival data to examine the behavior of the light curve from B to K.

Two recent works [1-2] have investigated Venus' O2 c-X and NO C-A nightglow from spectra taken by VIRTIS/Venus Express during the first year in orbit of the spacecraft. The O2 c(0)-X(v'') progression at 400-700 nm has been known for more than three decades. However, observations of this system from space or from Earth have been rare. The O2 a(0)-X

VISTA Variables in the Vía Láctea (VVV) is a public ESO near-IR variability survey aimed at scanning the Milky Way Bulge and an adjacent section of the mid-plane. VVV observations started in October 2009 during ESO science verification. Regular observations for the first year of the survey have been conducted since February 2010 and will cover a

We report on low-resolution spectroscopy of GX339-4 during its current, extended X-ray ``off'' state in May 2000 (r=20.1) obtained with the VLT Focal Reducer/low dispersion Spectrograph (FORS1). Although we do not positively detect the secondary star in GX339-4 we place an upper limit of 30 percent on the contribution of a ``normal'' K-type

Aims: The aim of the project is to characterise the two components of the brown dwarf system nearest to the Sun, WISE J104915.57-531906.1 (also called Luhman 16AB) at optical and near-infrared wavelengths. Methods: We obtained high signal-to-noise intermediate-resolution (R ~ 6000-11 000) optical (600-1000 nm) and near-infrared (1000-2480 nm)
