Structure of the SMC - Stellar component distribution from 2MASS data
I. Gonidakis, E. Livanou, E. Kontizas +5
The spatial distribution of the SMC stellar component is investigated from 2MASS data. The morphology of the different age populations is presented. The center of the distribution…
Towards a library of synthetic galaxy spectra and preliminary results of classification and parametrization of unresolved galaxies for Gaia
P. Tsalmantza, M. Kontizas, C. A. L. Bailer-Jones +8
Aims:The Gaia astrometric survey mission will, as a consequence of its scanning law, obtain low resolution optical (330-1000 nm) spectrophotometry of several million unresolved gal…
Star-forming Regions in the Small Magellanic Cloud Multi-wavelength Properties of Stellar Complexes
E. Livanou, I. Gonidakis, E. Kontizas +6
We trace the star formation regions in the SMC and study their properties. The size and spatial distribution of these regions is found to support the hierarchical scenario of star…
HST WFPC2 Observations of the Peculiar Main Sequence of the Double Star Cluster NGC 2011 in the Large Magellanic Cloud
D. A. Gouliermis, S. Lianou, M. Kontizas +2
We report the serendipitous discovery of a peculiar main sequence in archived Hubble Space Telescope WFPC2 observations of the young star cluster NGC 2011 in the Large Magellanic C…
Star-burst regions in the LMC
E. Livanou, M. Kontizas, I. Gonidakis +5
Aims. Filamentary structures of early type stars are found to be a common feature of the Magellanic Clouds formed at an age of about 0.9-2*10^8 yr. As we go to younger ages these l…
Luminous AGB stars in nearby galaxies. A study using Virtual Observatory tools
P. Tsalmantza, E. Kontizas, L. Cambresy +3
Aims. This study focuses on very luminous Mbol<-6.0 mag AGB stars with J-Ks>1.5 mag and H-Ks>0.4 mag in the LMC, SMC, M31, and M33 from 2MASS data. Methods.The data were taken from…
