Measurements of cosmic-ray secondary nuclei at high energies with the first flight of the CREAM balloon-borne experiment
H. S. Ahn, P. S. Allison, M. G. Bagliesi +34
We present new measurements of heavy cosmic-ray nuclei at high energies per- formed during the first flight of the balloon-borne cosmic-ray experiment CREAM (Cosmic-Ray Energetics…
Time-Evolving Photoionization: the Thin and Compact X-Ray Wind of NGC 4051
Fabrizio Nicastro, Yair Krongold, Martin Elvis +3
We discuss the power of time-evolving photoionization as a diagnostic tool to measure the electron density of photoionized gas. We apply this technique to a XMM-Newton observation…
The Far Ultraviolet Spectroscopic picture of the Missing Baryons in the Local Group
F. Nicastro, A. Zezas, M. Elvis +6
The number of detected baryons in the low-redshift Universe (z < 1) is far small er than the corresponding number of baryons observed at higher redshift. According to hydrodynamica…
An Empirical Ultraviolet Iron Spectrum Template Applicable to Active Galaxies
M. Vestergaard, B. J. Wilkes
Iron emission is often a severe contaminant in optical-ultraviolet spectra of active galaxies. Its presence complicates emission line studies. A viable solution, already successful…
