Are there Ghost Images of the Coma Cluster at other Redshifts?

P30: Are There Anxious Genes?

Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...

The Coma Cluster at γ-ray energies: multifrequency constraints

The Coma cluster exhibits evidence for a high-energetic non-thermal particle population. At frequencies > 1GHz recent radio halo observations confirm a significant spectral steepening of the volume-integrated emission. We calculate the volume-averaged high-energy spectrum due to inverse Compton scattering off the CMB radiation field and non-thermal bremsstrahlung according to an exponential cut...

Bars in field and cluster galaxies at intermediate redshifts

We present the first study of large-scale bars in clusters at intermediate redshifts (z = 0.4 − 0.8). We compare the properties of the bars and their host galaxies in the clusters with those of a field sample in the same redshift range. We use a sample of 945 moderately inclined disk galaxies drawn from the EDisCS project. The morphological classification of the galaxies and the detection of ba...

Dissecting the luminosity function of the Coma cluster of galaxies using CFHT wide field images

We determined the relative spatial density of the Coma cluster galaxies selected by luminosity, and the contribution of the galaxies of each central brightness to the luminosity function (i.e. the luminosity function bi–variate in central brightness). The Coma cluster and control fields were imaged using the CFH12K (42 × 28 arcmin) and UH8K (28 × 28 arcmin) wide–field cameras at the Canada–Fran...
