Accretion and nuclear activity of quiescent supermassive black holes. II: optical study and interpretation
Roberto Soria, Alister W. Graham, Giuseppina Fabbiano +5
Our X-ray study of the nuclear activity in a new sample of six quiescent early-type galaxies, and in a larger sample from the literature, confirmed (Soria et al., Paper I) that the…
Accretion and nuclear activity of quiescent supermassive black holes. I: X-ray study
Roberto Soria, Giuseppina Fabbiano, Alister W. Graham +5
We have studied the nuclear activity in a sample of six quiescent early-type galaxies, with new Chandra data and archival HST optical images. Their nuclear sources have X-ray lumin…
The X-ray emission properties and the dicothomy in the central stellar cusp shapes of early-type galaxies
S. Pellegrini
Hubble Space Telescope revealed a dicothomy in the central surface brightness profiles of early-type galaxies, that subsequently have been grouped into two families: core, boxy, an…
The nature of Composite Seyfert/Star-forming galaxies revealed by X-ray observations
F. Panessa, A. Wolter, S. Pellegrini +5
This paper presents new Chandra and BeppoSAX observations aimed at investigating the optical/X-ray mismatch in the enigmatic class of the Composite galaxies, discovered by a cross-…
Nuclear Accretion in Galaxies of the Local Universe: Clues from Chandra Observations
S. Pellegrini
In order to find an explanation for the radiative quiescence of supermassive black holes in the local Universe, for a sample of nearby galaxies the most accurate estimates are coll…
