The chemical abundances in the Galactic Centre from the atmospheres of Red Supergiants
Ben Davies, Livia Origlia, Rolf-Peter Kudritzki +3
The Galactic Centre (GC) has experienced a high degree of recent star-forming activity, as evidenced by the large number of massive stars currently residing there. The relative abu…
Probing the Galactic Bulge with deep Adaptive Optics imaging: the age of NGC 6440
L. Origlia, S. Lena, E. Diolaiti +4
We present first results of a pilot project aimed at exploiting the potentiality of ground based adaptive optics imaging in the near infrared to determine the age of stellar cluste…
Near-Infrared Photometry of Four Stellar Clusters in the Small Magellanic Cloud
Alessio Mucciarelli, Livia Origlia, Claudia Maraston +1
We present high-quality J, H and K photometry of four Small Magellanic Cloud stellar clusters with intermediate ages in the 1-7 Gyr range (namely NGC 339, 361, 416 and 419) . We ob…
High resolution infrared spectra of NGC 6440 and NGC 6441: two massive Bulge Globular Clusters
L. Origlia, E. Valenti, R. M. Rich
Using the NIRSPEC spectrograph at Keck II, we have obtained infrared echelle spectra covering the 1.5-1.8 micron range for giant stars in the massive bulge globular clusters NGC644…
The chemical composition of red giant stars in four intermediate-age clusters of the Large Magellanic Cloud
A. Mucciarelli, E. Carretta, L. Origlia +1
This paper presents the chemical abundance analysis of a sample of 27 red giant stars located in 4 popolous intermediate-age globular clusters in the Large Magellanic Cloud, namely…
A deep X-ray observation of M82 with XMM-Newton
Piero Ranalli, Andrea Comastri, Livia Origlia +1
We report on the analysis of a deep (100 ks) observation of the starburst galaxy M82 with the EPIC and RGS instruments on board the X-ray telescope XMM-Newton. The broad-band (0.5-…
