Producing baryons from neutralinos in small H2 clumps over cosmological ages
Edmond Giraud
Extreme scattering events in quasars suggest the existence of dark clumps of mass and size . Such clumps are extremely dense c…
Intergalactic stellar populations in intermediate redshift clusters
J. Melnick, E. Giraud, I. Toledo +2
A substantial fraction of the total stellar mass in rich clusters of galaxies resides in a diffuse intergalactic component usually referred to as the Intra-Cluster Light (ICL). The…
Anomaly distribution in quasar magnitudes: a test of lensing by an hypothetic Supergiant Molecular Cloud in the Galactic halo
Edmond Giraud
An anomaly in the distribution of quasar magnitudes based on the SDSS survey, has been recently reported by Longo (2012). The angular size of this anomaly is of the order of $\rm \…
Diffuse Intracluster Light at Intermediate Redshifts: ICL observations in a X-ray cluster at z=0.29
I. Toledo, J. Melnick, F. Selman +3
The diffuse intracluster light (ICL) contains a significant fraction of the total stellar mass in clusters of galaxies, and contributes in roughly equal proportion as the hot intra…
Preliminary results on the Extinction and Night Sky Background in UBV on La Silla and ALMA site
E. Giraud, G. Vasileiadis, P. Valvin +1
We report on measurements of the extinction in the U, B & V bands and of the NSB (Night Sky Background) during 2 dark periods on La Silla Observatory and at 4000-5000m on the ALMA…
An S-shaped arc in the galaxy cluster RXJ0054.0-2823
C. Faure, E. Giraud, J. Melnick +3
The center of the galaxy cluster RX J0054.0-2823 at z = 0.292 is a dynamically active region which includes an interacting system of three galaxies surrounded by a large halo of in…
