Jet-Disc coupling in the accreting black hole XTEJ1118+480
Julien Malzac, Andrea Merloni, Andrew C. Fabian
We interpret the rapid correlated UV/optical/ X-ray variability of XTEJ1118+480 as a signature of the coupling between the X-ray corona and a jet emitting synchrotron radiation in…
A fundamental plane of black hole activity: pushing forward the unification scheme
Andrea Merloni, Sebastian Heinz, Tiziana Di Matteo
We examine the disc--jet connection in stellar mass and supermassive black holes by investigating the properties of their compact emission in the hard X-ray and radio bands. We com…
Constraints on relativistic beaming from estimators of the unbeamed flux
S. Heinz, A. Merloni
We review the statistical properties of relativistic Doppler boosting relevant for studies of relativistic jets from compact objects based on radio--X-ray(--mass) correlations, suc…
Tracing the cosmological assembly of stars and supermassive black holes in galaxies
Andrea Merloni, Gregory Rudnick, Tiziana Di Matteo
We examine possible phenomenological constraints for the joint evolution of supermassive black holes (SMBH) and their host spheroids. We compare all the available observational dat…
Anti-Hierarchical Growth of Supermassive Black Holes and QSO lifetimes
Andrea Merloni
I present a new method to unveil the history of cosmic accretion and the build-up of Supermassive Black Holes (SMBH) in the nuclei of galaxies, based on observations of the evolvin…
Jet-disc coupling through a common energy reservoir in the black hole XTE J1118+480
Julien Malzac, Andrea Merloni, Andrew C. Fabian
We interpret the rapid correlated UV/optical/ X-ray variability of XTE J1118+480 as a signature of the coupling between the X-ray corona and a jet emitting synchrotron radiation in…
