Unveiling the nature of INTEGRAL objects through optical spectroscopy. VII. Identification of 20 Galactic and extragalactic hard X-ray sources
N. Masetti, P. Parisi, E. Palazzi +17
Within the framework of our program of assessment of the nature of unidentified or poorly known INTEGRAL sources, we present here spectroscopy of optical objects, selected through…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. VI. A multi-observatory identification campaign
N. Masetti, E. Mason, L. Morelli +18
Using 8 telescopes in the northern and southern hemispheres, plus archival data from two on-line sky surveys, we performed a systematic optical spectroscopic study of 39 putative c…
The AGN nature of 11 out of 12 Swift/RXTE unidentified sources through optical and X-ray spectroscopy
R. Landi, N. Masetti, L. Morelli +9
The Swift Burst Alert Telescope (BAT) is performing a high Galactic latitude survey in the 14-195 keV band at a flux limit of ~10^{-11} erg cm^{-2} s^{-1}, leading to the discovery…
Bright globular clusters in NGC 5128: the missing link between young massive clusters and evolved massive objects
M. Rejkuba, P. Dubath, D. Minniti +1
In order to investigate whether the brightest globular clusters (GCs) in the giant elliptical galaxies are similar to the less luminous GCs like those found in Local Group galaxies…
Oxygen, Sodium, Magnesium and Aluminium as tracers of the Galactic Bulge Formation
A. Lecureur, V. Hill, M. Zoccali +5
This paper investigates the peculiar behaviour of the light even (alpha-elements) and odd atomic number elements in red giants in the galactic bulge, both in terms of the chemical…
Properties of RR Lyrae stars in the inner regions of the Large Magellanic Cloud. II. The extended sample
J. Borissova, D. Minniti, M. Rejkuba +1
All galaxies that have been adequately examined so far have shown an extended stellar halo. To search for such a halo in the LMC we have obtained low-resolution spectra for 100 LMC…
