Pairing of Supermassive Black Holes in unequal-mass galaxy mergers
Simone Callegari, Lucio Mayer, Stelios Kazantzidis +4
We examine the pairing process of supermassive black holes (SMBHs) down to scales of 20-100 pc using a set of N-body/SPH simulations of binary mergers of disk galaxies with mass ra…
Pairing of Supermassive Black Holes in unequal-mass mergers
S. Callegari, L. Mayer, S. Kazantzidis
Disk galaxies with a spheroidal component are known to host Supermassive Black Holes (SMBHs) in their center. Unequal-mass galaxy mergers have been rarely studied despite the fact…
Intermediate-mass black holes and ultraluminous X-ray sources in the Cartwheel ring galaxy
M. Mapelli, B. Moore, L. Giordano +4
Chandra and XMM-Newton observations of the Cartwheel galaxy show ~17 bright X-ray sources (>~5x10^38 erg s^-1), all within the gas-rich outer ring. We explore the hypothesis that t…
On the inspiral of Massive Black Holes in gas-rich galaxy mergers
M. Colpi, S. Callegari, M. Dotti +2
We present a study on the dynamics of massive BHs in galaxy mergers, obtained from a series of high-resolution N-Body/SPH simulations. The presence of a gaseous component is essent…
