The Coronae of AB Dor and V471 Tau: Youth vs Tidal Spin-Up
We report on an analysis of high resolution Chandra spectra of two stars with very similar spectral types and rotation rates but with very different...
The Coronal Line Spectrum of the Brightest Seyfert Galaxies as Seen by ISO
The ISO coronal line spectrum of a sample of the brightest known Seyfert galaxies is presented and modeled. ISO observations of [O IV] 25.9 μ, [Ne V] 14.3 μ,...
The CoRoT space observatory was launched at the end of 2006 and has been delivering scientific data from early 2007 until its recent interruption, on 2 Nov...
The Correlation between Supermassive Black Hole Mass and the Structure of Ellipticals and Bulges
We demonstrate a strong correlation between supermassive black hole (SMBH) mass and the global structure of ellipticals and bulges: more centrally concentrated...
Ground based and HST imaging of quasars (see, e.g., Dunlop et al. 2003; Pagani et al. 2003 and references therein) clearly indicate that at z 0.5 quasars are...
The cosmic evolution of Starburst galaxies and AGN from the largest ISO survey
The huge improvement in sensitivity provided by the Infrared Space Observatory (ISO) offered the opportunity to probe the galaxy population to higher redshift...
