Comments on ``Are Swift Gamma-Ray Bursts consistent with the Ghirlanda relation?", by Campana et al.(astro--ph/0703676)
G. Ghirlanda, L. Nava, G. Ghisellini +1
In their recent paper, Campana et al. (2007) found that 5 bursts, among those detected by Swift, are outliers with respect to the E_peak-E_gamma ("Ghirlanda") correlation. We inste…
Rotation of Hot Horizontal Branch Stars in Galactic Globular Clusters
A. Recio-Blanco, G. Piotto, A. Aparicio +1
We present high resolution UVES+VLT spectroscopic observations of 61 stars in the extended blue horizontal branches of the Galactic globular clusters NGC 1904 (M79), NGC 2808, NGC…
Statistical Synthesis Models
M. Cervino, V. Luridiana
In this contribution we evaluate the minimal cluster mass for which the effects of an incomplete sampling of the Initial Mass Function (IMF) cannot be neglected. This minimal clust…
How to determine the star formation histories in spiral disks
M. Molla, E. Hardy
We have computed 500 chemical evolution models for the galaxy NGC 4303. With the obtained evolutionary histories and a synthesis model we have also calculated the spectral indices…
A multiwavelength vision of star forming regions: What does lambda_1 know about lambda_2?
M. Cervino
In this contribution I show the physical limitations to the application of standard synthesis models from 0 to 10 Gyr. I also present the multiwavelength spectrum (from gamma-rays…
