Activity induced by Gravitational Interaction in Galaxy Pairs
D. Dultzin, J. J. Gonzalez, Y. Krongold +6
A systematic study of the nuclear emission of a sample of 97 spirals in isolated galaxy pairs with mixed morphology (E+S) shows that: 1) AGN activity is found in 40% of the spiral…
The big blue bump and soft X-ray excess of individual quasars
Sinhue A. R. Haro-Corzo, Luc Binette, Yair Krongold
For 11 quasar, we find that the soft X-ray excess component is not prolongation of the Big Blue Bump. Furthermore, adopting a theoretical continuum that is absorbed by the appropri…
X-ray properties of a sample of polar-scattered Seyfert galaxies
E. Jimenez-Bailon, M. Guainazzi, G. Matt +5
We present the results on an XMM-Newton systematic analysis of a sample of nine Seyfert 1 galaxies. When observed in polarised light, the spectra of the selected sources are simila…
The Nature of the Far-UV Break in the Energy Distribution of Quasars
L. Binette, S. Haro-Corzo, Y. Krongold +1
A prominent continuum steepening is observed in quasar energy distributions near 1100A. We review possible interpretations for the physical origin of this so-called far-UV break.
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…
A Mass Measurement for the Missing Baryons in the Warm-Hot Intergalactic Medium via the X-ray Forest
F. Nicastro, S. Mathur, M. Elvis +7
Recent Cosmological measurements indicate that baryons comprise about four percent of the total mass-energy density of the Universe, which is in accord with the predictions arising…
