Hierarchical star formation in nearby galaxies
María Jimena Rodríguez, Gustavo Baume, Carlos Feinstein
Aims: The purpose of this work is to study the properties of the spatial distribution of the young population in three nearby galaxies in order to better understand the first stage…
The young stellar population in NGC 247 Main properties and hierarchical clustering
M. J. Rodríguez, G. Baume, C. Feinstein
The aim of this work is to investigate the characteristics of the young stellar population in the spiral galaxy NGC 247. In particular, we focused our attention in its hierarchical…
VVV DR1: The First Data Release of the Milky Way Bulge and Southern Plane from the Near-Infrared ESO Public Survey VISTA Variables in the Via Lactea
R. K. Saito, M. Hempel, D. Minniti +107
The ESO Public Survey VISTA Variables in the Via Lactea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for…
Polarimetry of an Intermediate-age Open Cluster: NGC 5617
Ana Maria Orsatti, Carlos Feinstein, M. Marcela Vergne +2
We present polarimetric observations in the UBVRI bands of 72 stars located in the direction of the medium age open cluster NGC 5617. Our intention is to use polarimetry as a tool…
Optical polarization observations in the Scorpius region: NGC 6124
M. Marcela Vergne, Carlos Feinstein, Ruben Martinez +2
We have obtained optical multicolour (UBVRI) linear polarimetric data for 46 of the brightest stars in the area of the open cluster NGC 6124 in order to investigate the properties…
VISTA Variables in the Via Lactea (VVV): The public ESO near-IR variability survey of the Milky Way
D. Minniti, P. W. Lucas, J. P. Emerson +63
We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge and an adjacent section of the mid-plane where star formation activity is high. The survey…
