Optical and IR observations of SN 2002dj: some possible common properties of fast expanding SNe Ia
G. Pignata, S. Benetti, P. A. Mazzali +17
As part of the European Supernova Collaboration we obtained extensive photometry and spectroscopy of the type Ia SN 2002dj covering epochs from 11 days before to nearly two years a…
Galaxy Clusters in the Line of Sight to Background Quasars: I. Survey Design and Incidence of MgII Absorbers at Cluster Redshifts
S. Lopez, L. F. Barrientos, P. Lira +7
We describe the first optical survey of absorption systems associated with galaxy clusters at z= 0.3-0.9. We have cross-correlated SDSS DR3 quasars with high-redshift cluster/group…
Tomography of the intergalactic medium with Ly-alpha forests in close QSO pairs
V. D'Odorico, M. Viel, F. Saitta +6
We study the three-dimensional distribution of non virialised matter at z~2 using high resolution spectra of QSO pairs and simulated spectra drawn from cosmological hydrodynamical…
Cataclysmic variables from the Calan-Tololo-Survey -- I. Photometric periods
C. Tappert, T. Augusteijn, J. Maza
In a search for cataclysmic variables in the Calan-Tololo Survey we have detected 21 systems, 16 of them previously unknown. In this paper we present detailed time-series photometr…
Long slit spectroscopy of a sample of isolated spirals with and without an AGN
I. Marquez, F. Durret, J. Masegosa +6
We present the kinematical data obtained for a sample of active (Seyfert) and non active isolated spiral galaxies, based on long slit spectra along several position angles in the H…
Are the hosts of Gamma-Ray Bursts sub-luminous and blue galaxies?
E. Le Floc'h, P. -A. Duc, I. F. Mirabel +11
We present K-band imaging observations of ten Gamma-Ray Burst (GRB) host galaxies. We compare their observed and absolute K magnitudes as well as their R-K colours with those of ot…
