Self-consistent physical parameters for MC clusters from CMD modelling: application to SMC clusters observed with the SOAR telescope
Bruno M. S. Dias, Leandro O. Kerber, Basílio X. Santiago +2
The Magellanic Clouds (MCs) present a rich system of stellar clusters that can be used to probe the dynamical and chemical evolution of these neighboring and interacting irregular…
The evolution of the brightest cluster galaxies since z~1 from the ESO Distant Cluster Survey (EDisCS)
I. M. Whiley, A. Aragon-Salamanca, G. De Lucia +13
[Abridged] We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey. These data are combined with photometry from Aragon-Salamanca et al…
The reflecting surface of the MAGIC-II Telescope
D. Bastieri, J. Arnold, C. Baixeras +19
The MAGIC Collaboration is building a second telescope, MAGIC II, improving the design of the current MAGIC Telescope. MAGIC II is being built at 85 m of distance from MAGIC I, and…
The luminous host galaxies of high redshift BL Lac objects
J. K. Kotilainen, T. Hyvonen, R. Falomo
(abridged) We present near-infrared Ks-band imaging of 13 high redshift (0.6 < z < 1.3) BL Lac objects. We clearly detect the host in eight objects, and marginally in three others.…
Abundance stratification in Type Ia supernovae - I. The case of SN 2002bo
M. Stehle, P. A. Mazzali, S. Benetti +1
The abundance stratification in the ejecta of the normal Type Ia supernova 2002bo is derived by fitting a series of spectra obtained at close time intervals. A Monte Carlo code, mo…
Modelling the Spectral Energy Distribution of Compact Luminous Infrared Galaxies: Constraints from High Frequency Radio Data
O. R. Prouton, A. Bressan, M. Clemens +3
We have performed 23 GHz VLA observations of 7 compact, luminous infrared galaxies, selected to have evidence of starburst activity. New and published multi-frequency data are comb…
Automated Determination of Stellar Population Parameters in Galaxies Using Active Instance-based Learning
Thamar Solorio, Olac Fuentes, Roberto Terlevich +2
In this work we focus on the determination of the relative distributions of young, intermediate-age and old populations of stars in galaxies. Starting from a grid of theoretical po…
Radio Loud AGN in the Context of the Eigenvector 1 Parameter Space
J. W. Sulentic, S. Zamfir, P. Marziani +3
We consider the properties of radio-loud (RL) AGN in the context of the Eigenvector 1 (E1) parameter space. RL sources show a restricted E1 parameter space occupation relative to t…
Spectroscopy, Photometry and Micro-arcsec Astrometry of Binaries with the GAIA Space Mission and with the RAVE Experiment
Tomaz Zwitter, Ulisse Munari
GAIA astrometric mission of ESA will be very efficient in discovering binary and multiple stars with any orbital period, from minutes to millions of years. Main parameters of the r…
Mass of BL Lacs from the Velocity Dispersion of the Host Galaxy
A. Treves, N. Carangelo, R. Falomo +1
We report on new measurements of the stellar velocity dispersion of 4 BL Lac objects for which optical spectroscopy was gathered at the ESO 3.6m using EFOSC2. Assuming the M(BH)--(…
A search for Symbiotic Stars in the Local Group
Laura Magrini, Romano L. M. Corradi, Ulisse Munari
The Local Group Census is a narrow- and broad-band survey of all the galaxies of the Local Group above dec = -30 deg, in progress at the 2.5m Isaac Newton telescope on La Palma. We…
Spiral and irregular galaxies in the Hubble Deep Field North - Comparison with early types and implications for the global SFR density
G. Rodighiero, G. L. Granato, A. Franceschini +2
We analyze a morphologically-selected complete sample of 52 late-type (spiral and irregular) galaxies in the Hubble Deep Field North with total K-magnitudes brighter than K=20.47.…
The bright 175um knots of the Andromeda Galaxy
L. Schmidtobreick, M. Haas, D. Lemke
Discrete far-infrared (FIR) sources of M31 are identified in the ISO 175um map and characterized via their FIR colours, luminosities and masses. With a mean size of 800pc, they pro…
The red giant branches of Galactic globular clusters in the [(V-I)o,Mv] plane: metallicity indices and morphology
Ivo Saviane, Alfred Rosenberg, Giampaolo Piotto +1
The purpose of this study is to carry out a thorough investigation of the changes in morphology of the red giant branch (RGB) of Galactic globular clusters (GGC) as a function of m…
The stellar populations of the Fornax dwarf spheroidal galaxy
Ivo Saviane, Enrico V. Held, Gianpaolo Bertelli
(abridged) We present B,V,I CCD photometry of about 40000 stars in four regions of the Fornax dSph. Using the resultant CMDs, many already known age-tracers are investigated, and n…
