The spectral structure and energetics of powerful radio sources
(2014-04-29)
Determining the energy spectrum of an electron population can give key insights into the underlying physics of a radio source; however, the lack of high resolution, broad-bandwidth observations has left many ambiguities ...
Stromgren photometric survey in the Galactic anticenter direction
(2012-11-16)
Aims. The main purpose is to map the radial variation of the stellar space density for the young stellar population in the Galactic anticenter direction in order to understand the structure and location of the Perseus ...
Elemental and isotopic abundances and chemical evolution of galaxies
(Astronomical Society of the Pacific, 2012-02-15)
Elemental and isotopic abundances are the fossils of galactic archaeology. The observed [X/Fe]-[Fe/H] relations in the Galactic bulge and disk and the mass-metallicity relation of galaxies are roughly reproduced with ...
A Herschel study of YSO evolutionary stages and formation timelines in two fields of the Hi-GAL survey
(2010-05-11)
We present a first study of the star-forming compact dust condensations revealed by Herschel in the two 2 \times 2 \degr Galactic Plane fields centered at [l;b] = [30\degr; 0 \degr] and [l;b] = [59\degr; 0 \degr], respectively, ...
