Radiodetection of Cosmic Ray Extensive Air Showers
D. Ardouin, A. Belletoile, D. Charrier +12
We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
Galaxy transmutations: The double ringed galaxy ESO 474-G26
V. Reshetnikov, F. Bournaud, F. Combes +4
Surface photometry and a 21cm HI line spectrum of the giant double-ringed galaxy ESO 474-G26 are presented. The morphology of this system is unique among the 30,000 galaxies with >…
Dynamical triggering of starbursts
F. Combes
Galaxy interactions/mergers, gravitational instabilities and density waves, such as bars, are frequently invoked to trigger starbursts. These mechanisms have been explored through…
Radio Detection of Cosmic Ray Extensive Air Showers: present status of the CODALEMA experiment
A. Belletoile, D. Ardouin, D. Charrier +10
Data acquisition and analysis for the CODALEMA experiment, in operation for more than one year, has provided improved knowledge of the characteristics of this new device. At the sa…
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…
Kinematics of tidal tails in interacting galaxies: Tidal Dwarf Galaxies and projection effects
F. Bournaud, P. -A. Duc, P. Amram +2
The kinematics of tidal tails in colliding galaxies has been studied via Fabry-Perot observations of the Halpha emission. With their large field of view and high spatial resolution…
Secular evolution versus hierarchical merging: galaxy evolution along the Hubble sequence, in the field and rich environments
Francoise Combes
In the current galaxy formation scenarios, two physical phenomena are invoked to build disk galaxies: hierarchical mergers and more quiescent external gas accretion, coming from in…
The role of bars
Francoise Combes
Secular evolution and fueling is driven by bars in spiral galaxies, and the related dynamical processes are reviewed. It is shown that gravity torques dominate over viscous torques…
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…
