Multiscale modelling in nuclear ferritic steels: from nano-sized defects to embrittlement
N. Castin, G. Bonny, M. J. KonstantinoviÄ +12
Radiation-induced embrittlement of nuclear steels is one of the main limiting factors for safe long-term operation of nuclear power plants. In support of accurate and safe reactor…
SINFONI in the Galactic Center: young stars and IR flares in the central light month
F. Eisenhauer, R. Genzel, T. Alexander +18
We report 75 milli-arcsec resolution, near-IR imaging spectroscopy within the central 30 light days of the Galactic Center [...]. To a limiting magnitude of K~16, 9 of 10 stars in…
The M 31 double nucleus probed with OASIS and HST. A natural m=1 mode?
R. Bacon, E. Emsellem, F. Combes +3
We present observations with the adaptive optics assisted integral field spectrograph OASIS of the M 31 double nucleus at a spatial resolution better than 0.5 arcsec FWHM. These da…
The SAURON project. I. The panoramic integral-field spectrograph
R. Bacon, Y. Copin, G. Monnet +10
A new integral-field spectrograph, SAURON, is described. It is based on the Tiger principle, and uses a lenslet array. SAURON has a large field of view and high throughput, and all…
SINFONI - Integral Field Spectroscopy at 50 milli-arcsecond resolution with the ESO VLT
F. Eisenhauer, H. Bonnet, R. Abuter +21
SINFONI is an adaptive optics assisted near-infrared integral field spectrometer for the ESO VLT. The Adaptive Optics Module (built by the ESO Adaptive Optics Group) is a 60-elemen…
SAURON Observations of Disks in Early-Type Galaxies
M. Bureau, Y. Copin, E. K. Verolme +9
We briefly describe the SAURON project, aimed at determining the intrinsic shape and internal dynamics of spheroids. We focus here on the ability of SAURON to identify gaseous and…
Sub-Arcsecond 2D Photometry and Spectrography of the Nucleus of M31: The Supermassive Black Hole Revisited
R. Bacon, E. Emsellem, G. Monnet +1
Sub-arcsecond imagery (HRCAM, 0".35 - 0".57 FWHM) and two-dimensional spectrography (TIGER, 0".9 FWHM) of the central nucleus of M31 have been obtained at CFHT. The photometric dat…
The SAURON project. II. Sample and early results
P. T. de Zeeuw, M. Bureau, E. Emsellem +9
Early results are reported from the SAURON survey of the kinematics and stellar populations of a representative sample of nearby E, S0 and Sa galaxies. The survey is aimed at deter…
The FALCON concept: multi-object spectroscopy combined with MCAO in near-IR
F. Hammer, F. Sayède, E. Gendron +16
A large fraction of the present-day stellar mass was formed between z=0.5 and z~3 and our understanding of the formation mechanisms at work at these epochs requires both high spati…
Galaxy mapping with the SAURON integral-field spectrograph: The star formation history of NGC 4365
Roger L. Davies, Harald Kuntschner, Eric Emsellem +9
We report the first wide-field mapping of the kinematics and stellar populations in the E3 galaxy NGC 4365. The velocity maps extend previous long-slit work. They show two independ…
Star-formation at z=4.7 in the environment of the QSO BR1202-07
A. Fontana, S. D'Odorico, E. Giallongo +3
We present here the spectrum of the galaxy companion to the z=4.7 quasar BR1202-0725, in the optical range 6000-9000 A, corresponding to 1050-1580 A rest-frame. We detect a strong…
Ionized Gas in Spheroids: The SAURON Survey
D. Krajnovic, R. Bacon, M. Bureau +11
Early results are reported from the SAURON survey of the kinematics and stellar populations of nearby cluster and field E, S0, and Sa galaxies. We present maps of the Hbeta and [OI…
Adaptive optics imaging of low and intermediate redshift quasars
I. Marquez, P. Petitjean, B. Theodore +3
We present the results of adaptive-optics imaging in the H and K bands of 12 low and intermediate redshift (z<0.6) quasars using the PUEO system mounted on the Canada-France-Hawaii…
