Search for Giant Planets around White Dwarfs with HST, Spitzer, and VLT
S. Friedrich, H. Zinnecker, S. Correia +3
For the last three years we have performed a survey for young (<3 Gyrs) giant planets around nearby white dwarfs with HST, Spitzer, and VLT. Direct HST/NICMOS imaging of the seven…
The Galactic Halo density distribution from photometric survey data: results of a pilot study
M. Cignoni, V. Ripepi, M. Marconi +4
Our goal is to recover the Galactic Halo spatial density by means of field stars. To this aim, we apply a new technique to the Capodimonte Deep Field (OACDF, Alcala' et al. 2004),…
Chandra point-source counts in distant galaxy clusters
M. Branchesi, I. M. Gioia, C. Fanti +2
With the superb angular resolution of the Chandra Observatory, it is now possible to detect X-ray point sources, either embedded in galaxy clusters or along the cluster line of sig…
Vanishing chiral couplings in the large-N_C resonance theory
Jorge Portoles, Ignasi Rosell, Pedro Ruiz-Femenia
The construction of a resonance theory involving hadrons requires implementing the information from higher scales into the couplings of the effective Lagrangian. We consider the la…
Integrated specific star formation rates of galaxies, groups, and clusters: A continuous upper limit with stellar mass?
Georg Feulner, Ulrich Hopp, Christine S. Botzler
Aims: We investigate the build-up of stellar mass through star formation in field galaxies, galaxy groups, and clusters in order to better understand the physical processes regulat…
The X-Ray Luminosity--Mass Relation for Local Clusters of Galaxies
R. Stanek, A. E. Evrard, H. Böhringer +2
We investigate the relationship between soft \xray luminosity and mass for low redshift clusters of galaxies by comparing observed number counts to expectations of CDM cosmologi…
