Quantum Origin of the Primordial Fluctuation Spectrum and its Statistics
Quantum Origin Primordial Fluctuation Spectrum Statistics
2011/10/9
The account of the origin of cosmic structure, as provided by the standard inflationary paradigm, is not fully satisfactory, as has been argued in Perez et al 2006. The central point of that work is t...
Multiwavelength campaign on Mrk 509. III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
Active Galactic Nuclei – X-ray spectroscopy – XMM-Newton – outfl ows – individual: Mrk 509 – galaxies: Seyfert
2011/9/27
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized outflow with an unpr...
The fragmentation of expanding shells III: Oligarchic accretion and the mass spectrum of fragments
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We use SPH simulations to investigate the gravitational fragmentation of expanding shells through the linear and non--linear regimes.
Power Spectrum Analysis of Physikalisch-Technische Bundesanstalt Decay-Rate Data: Evidence for Solar Rotational Modulation
Solar and Stellar Astrophysics (astro-ph.SR) Nuclear Experiment (nucl-ex) Instrumentation and Detectors (physics.ins-det)
2010/12/29
Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes.
Stark widths (W) and shifts (d) of 5 prominent triply ionized
oxygen (O IV) spectral lines in 3 multiplets have been measured in oxygen plasma
at 42 000 K electron temperature using a linear, low-pr...
