Centaurus a: VLT Views of the Nearest Giant Elliptical Galaxy
(s/iCordoba, 2002)
VLT images in BVI are used to identify globular clusters in the central region of NGC5128. Based on the sizes, optical magnitudes and colors, a hundred candidate globular clusters are identified with projected galactocentric ...
Kinematics of the Outer Cluster System of NGC 1399
(s/i, 2004)
We present preliminary results of our dynamical study of the outer globular cluster system of NGC 1399, the central galaxy in the Fornax cluster. About 160 new radial velocities for globular clusters at projected galactocentric ...
The Edge of the Young Galactic Disk
(2010)
In this work we report and discuss the detection of two distant diffuse stellar groups in the third Galactic quadrant. They are composed of young stars, with spectral types ranging from late O to late B, and lie at ...
A parametric study on the formation of extended star clusters and ultra-compact dwarf galaxies
(2011)
Context. In the last decade, very extended old stellar clusters with masses in the range from a few 104 to 108 M⊙ have been found in various types of galaxies in different environments. Objects with masses comparable to ...
Open clusters towards the Galactic centre: chemistry and dynamics. A VLT spectroscopic study of NGC 6192, NGC 6404, NGC 6583
(2010)
Context. In the framework of the study of the Galactic metallicity gradient and its time evolution, we present new high-resolution spectroscopic observations obtained with FLAMES and the fiber link to UVES at VLT of three ...
Three Galactic globular cluster candidates
(2011)
The census of Galactic globular clusters (GCs) is still incomplete, and about ten new objects are supposed to await discovery, hidden behind the crowded and reddened regions of the Galactic bulge and disk. We investigated ...
The assembly history of the Galactic inner halo inferred from alpha-element patterns
(2019)
We explore the origin of the observed decline in [O/Fe] and [Mg/Fe]) with Galactocentric distance for high-metallicity stars ([Fe/H] > -1.1), based on a sample of halo stars selected within the Apache Point Observatory ...
The edge of the young Galactic disk
(Iop Publishing, 2010-08)
In this work, we report and discuss the detection of two distant diffuse stellar groups in the third Galactic quadrant. They are composed of young stars, with spectral types ranging from late O to late B, and lie at ...
Molecular gas, kinematics, and OB star formation in the spiral arms of the southern Milky Way
(UNIV CHICAGO PRESS, 2006-04-20)
The rotation curve for the fourth Galactic quadrant within the solar circle is derived from the Columbia University - Universidad de Chile CO (J = 1 -> 0) survey of molecular gas. A new sampling, 4 times denser in longitude ...
