Correlated mixtures of adiabatic and isocurvature cosmological perturbations
David Langlois, Alain Riazuelo
We examine the consequences of the existence of correlated mixtures of adiabatic and isocurvature perturbations on the CMB and large scale structure. In particular, we consider the…
Optical integral field spectroscopy of the extended line emission around six radio-loud quasars
C. S. Crawford, C. Vanderriest
We present integral field spectroscopy of a small sample of radio-loud quasars at intermediate redshift (0.26<z<0.60), most of which are associated with large radio sources. All ha…
Morphological and Star Formation Evolution to z=1
F. Hammer
The decrease, since z=1, of the rest-frame UV luminosity density is related to global changes in morphology, color and emission lines properties of galaxies. This is apparently fol…
Statistical properties of local and intermediate z galaxies
F. Hammer
Galaxy evolution during the last 9 Gyr is discussed. It can be traced back from well known present-day galaxies or directly observed for galaxies at different look back times. This…
X-ray plasma diagnostics for totally and partially photoionized plasmas such as Warm Absorber in AGN
Delphine Porquet, Jacques Dubau
Thanks to the new generation of X-ray satellites such as Chandra and XMM, high resolution and high sensitivity spectra are available. In particular, for the first time, the three m…
Tidal Tails around 20 Galactic Globular Clusters
Georges Meylan, Stephane Leon, Francoise Combes
We present our study of the 2-D structures of the tidal tails associated with 20 galactic globular clusters, structures obtained by using the wavelet transform to detect weak struc…
