Did most present-day spirals form during the last 8 Gyrs? A formation history with violent episodes revealed by panchromatic observations
F. Hammer, H. Flores, D. Elbaz +3
(abridged) Studies of distant galaxies have shown that ellipticals and large spirals were already in place 8 Gyr ago, leading to a very modest recent star formation in intermediate…
Atomic carbon in PSS 2322+1944, a quasar at redshift 4.12
J. Pety, A. Beelen, P. Cox +4
We report the detection of the 3P1 to 3P0 fine-structure line of neutral carbon in the z=4.12 quasar PSS 2322+1944, obtained at the IRAM Plateau de Bure interferometer. The CI 3P1-…
A method for determining radio continuum spectra, and its application to large surveys
B. Vollmer, E. Davoust, P. Dubois +3
A new tool to extract cross-identifications and radio continuum spectra from radio catalogues contained in the VIZIER database of the CDS is presented. The code can handle radio su…
X-ray Variability of AGN and the Flare Model
R. W. Goosmann, B. Czerny, A. -M. Dumont +2
Short-term variability of X-ray continuum spectra has been reported for several Active Galactic Nuclei. Significant X-ray flux variations are observed within time scales down to 10…
Flare-induced fountains and buried flares in AGN
B. Czerny, R. Goosmann
We discuss the local physical changes at the surface of an AGN accretion disk after the onset of a magnetic flare. The X-ray irradiation by a flare creates a hot spot at the disk s…
Very Luminous Carbon Stars in the Outer Disk of the Triangulum Spiral Galaxy
D. L. Block, K. C. Freeman, T. H. Jarrett +4
Stars with masses in the range from about 1.3 to 3.5 Mo pass through an evolutionary stage where they become carbon stars. In this stage, which lasts a few Myr, these stars are ext…
The photospheric abundances of active binaries III. Abundance peculiarities at high activity level
T. Morel, G. Micela, F. Favata +1
We report the determination from high-resolution spectra of the atmospheric parameters and abundances of 13 chemical species (among which lithium) in 8 single-lined active binaries…
Multi-wavelength analysis of the dust emission in the Small Magellanic Cloud
C. Bot, F. Boulanger, G. Lagache +2
We present an analysis of dust grain emission in the diffuse interstellar medium of the Small Magellanic Cloud (SMC). This study is motivated by the availability of 170 microns ISO…
Unequal-mass galaxy merger remnants: spiral-like morphology but elliptical-like kinematics
Frederic Bournaud, Francoise Combes, Chanda J. Jog
It is generally believed that major galaxy mergers with mass ratios in the range 1:1-3:1 result in remnants that have properties similar to elliptical galaxies, and minor mergers b…
Halpha Kinematics of Tidal Tails in Interacting Systems: Projection Effects and Dark Matter in TDGs
P. Amram, F. Bournaud, P. -A. Duc
Several interacting systems exhibit at the tip of their long tidal tails massive condensations of atomic hydrogen, which may be the progenitors of Tidal Dwarf Galaxies. Because, qu…
The effect of metallicity on the Cepheid Period-Luminosity relation from a Baade-Wesselink analysis of Cepheids in the Galaxy and in the Small Magellanic Cloud
Jesper Storm, Bruce W. Carney, Wolfgang P. Gieren +3
(ABRIDGED) We have applied the near-IR Barnes-Evans realization of the Baade-Wesselink method as calibrated by Fouque & Gieren (1997) to five metal-poor Cepheids with periods betwe…
BVRIJK light curves and radial velocity curves for selected Magellanic Cloud Cepheids
Jesper Storm, Bruce W. Carney, Wolfgang P. Gieren +4
We present high precision and well sampled BVRIJK light curves and radial velocity curves for a sample of five Cepheids in the SMC. In addition we present radial velocity curves fo…
