Hard X-ray colours of Neutron Star and Black Hole Low Mass X-ray Binaries with INTEGRAL
Simon E. Shaw, Ada Paizis, Nami Mowlavi +3
The X-ray spectra of Low Mass X-ray Binaries (LMXB) can change on short time-scales, making it difficult to follow their spectral characteristics in detail through model fitting. C…
The VIRMOS-VLT Deep Survey: the last 10 billion years of evolution of galaxy clustering
A. Pollo, L. Guzzo, O. Le Fevre +46
We discuss the evolution of clustering of galaxies in the Universe from the present epoch back to z ~ 2, using the first-epoch data from the VIMOS-VLT Deep Survey (VVDS). We presen…
Witnessing the build-up of the colour-density relation
O. Cucciati, A. Iovino, C. Marinoni +50
We investigate the redshift and luminosity evolution of the galaxy colour-density relation using the data from the First Epoch VIMOS-VLT Deep Survey (VVDS) on scales of R=5 h^(-1)M…
The VLT-VIMOS Mask Preparation Software
D. Bottini, B. Garilli, D. Maccagni +34
VIMOS (VIsible Multi-Object Spectrograph) is a multi-object imaging spectrograph installed at the VLT (Very large Telescope) at the ESO (European Southern Observatory) Paranal Obse…
VVDS: early results on LSS distribution to z~1.5
O. Le Fèvre, G. Vettolani, D. Maccagni +2
The VIMOS VLT Deep Survey (VVDS) is an on-going program to map the evolution of galaxies, large scale structures and AGNs from the redshift measurement of more than 100000 objects…
Very rapid optical variability of PKS 2155-304
S. Paltani, T. J. -L. Courvoisier, A. Blecha +1
We have performed an optical observation campaign on PKS 2155-304, whose aim was to determine the variability properties of this object on very short time scales in several photome…
