Stellar and total baryon mass fractions in groups and clusters since redshift 1
S. Giodini, D. Pierini, A. Finoguenov +24
We investigate if the discrepancy between estimates of the total baryon mass fraction obtained from observations of the cosmic microwave background (CMB) and of galaxy groups/clust…
The impact of baryons on dark matter haloes
Susana E. Pedrosa, Patricia B. Tissera, Cecilia Scannapieco
We analyse the dark matter (DM) distribution in a approx 10^12 M_sun halo extracted from a simulation consistent with the concordance cosmology, where the physics regulating the tr…
Star complexes and stellar populations in NGC 6822 - Comparison with the Magellanic Clouds
A. Karampelas, A. Dapergolas, E. Kontizas +4
The star complexes (large scale star forming regions) of NGC 6822 were traced and mapped and their size distribution was compared with the size distribution of star complexes in th…
Parity violation constraints using 2006-2007 QUaD CMB polarization spectra
QUaD Collaboration, E. Y. S. Wu, P. Ade +29
We constrain parity-violating interactions to the surface of last scattering using spectra from the QUaD experiment's second and third seasons of observations by searching for a po…
Multiline Zeeman signatures as demonstrated through the Pseudo-line
M. Semel, J. C. Ramirez Velez, M. J. Stift +3
In order to get a significant Zeeman signature in the polarised spectra of a magnetic star, we usually 'add' the contributions of numerous spectral lines; the ultimate goal is to r…
A Full Year's Chandra Exposure on SDSS Quasars from the Chandra Multiwavelength Project
Paul J. Green, T. L. Aldcroft, G. T. Richards +13
We study the spectral energy distributions and evolution of a large sample of optically selected quasars from the Sloan Digital Sky Survey (SDSS) that were observed in 323 Chandra…
