Have loose globular clusters collapsed yet?
Guido De Marchi, Francesco Paresce, Luigi Pulone
We report on the discovery of a surprising observed correlation between the slope of the low-mass stellar global mass function (GMF) of globular clusters (GCs) and their central co…
Tidal disruption and the tale of three clusters
Guido De Marchi, Francesco Paresce, Luigi Pulone
How well can we tell whether a globular cluster will survive the Galaxy's tidal forces? This is conceptually easy to do if we know the cluster's total mass, mass structure and spac…
VLTI/VINCI observations of the nucleus of NGC 1068 using the adaptive optics system MACAO
M. Wittkowski, P. Kervella, R. Arsenault +3
We present the first near-infrared K-band long-baseline interferometric measurement of the prototype Seyfert 2 galaxy NGC 1068 with resolution lambda/B \~ 10 mas obtained with the…
The mass function of M4 from near IR and optical HST observations
L. Pulone, G. De Marchi, F. Paresce
Deep images of the galactic globular cluster M4 taken at various locations with the NIC3 and the WFPC2 cameras on HST were used to derive detailed local optical and near IR luminos…
A Deep Optical Luminosity Function of NGC 6712 with the VLT: Evidence for Severe Tidal Disruption
Guido De Marchi, Bruno Leibundgut, Francesco Paresce +1
The VLT on Cerro Paranal was used to observe four fields located at 2.3' from the center of the Galactic globular cluster NGC 6712 in the V and R bands. The resulting color-magnitu…
