New variable stars discovered in the fields of three Galactic open clusters using the VVV survey
(Elsevier Science, 2016-11)
This project is a massive near-infrared (NIR) search for variable stars in highly reddened and obscured open cluster (OC) fields projected on regions of the Galactic bulge and disk. The search is performed using photometric ...
NGC2587: a sparse open cluster projected on to a populous star field
(Oxford University Press, 2009-07)
We present CCD photometry in the Johnson U, B and V and Kron–Cousins I passbands for the open cluster NGC 2587. The sample consists of 4406 stars reaching down to V∼ 21.0. We developed a new method to clean statistically ...
Mapping the stellar age of the Milky Way bulge with the VVV II. Deep JK(s) catalog release based on PSF photometry
(2019)
Context. The bulge represents the best compromise between old and massive Galactic components, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way formed and evolved. In addition, ...
The nature of UCDs: Internal dynamics from an expanded sample and homogeneous database
(2008)
We have obtained high-resolution spectra of 23 ultra-compact dwarf galaxies (UCDs) in the Fornax cluster with -10.4>M_V>-13.5 mag (10^6<M/M_*<10^8), using FLAMES/Giraffe at the VLT. This is the largest homogeneous data set ...
Old main-sequence turnoff photometry in the small magellanic cloud. I. Constraints on the star formation history in different fields
(2007)
We present ground-based B-and R-band color-magnitude diagrams (CMDs) reaching the oldest main-sequence (MS) turnoffs with good photometric accuracy for 12 fields in the Small Magellanic Cloud (SMC). Our fields, located ...
The Araucaria project - improving stellar distance indicatorsVariable Stars in the Local Group, IAU Colloquium 193

The VLT LBG Redshift Survey - III. The clustering and dynamics of Lyman-break galaxies at z~3
(Wiley-blackwell Publishing, Inc, 2013-03)
We present a catalogue of 2135 galaxy redshifts from the VLT LBG Redshift Survey (VLRS), a spectroscopic survey of z ~ 3 galaxies in wide fields centred on background quasi-stellar objects. We have used deep optical imaging ...
Mapping dark matter in the Milky Way, a synopsis
(2015-01-01)
Mapping the dark matter distribution across our Galaxy represents a central challenge for the near future as a new generation of space-borne and ground-based astronomical surveys swiftly comes online. Here we present a ...
