Size matters: are we witnessing super-Eddington accretion in high-redshift black holes from JWST?
Alessandro Lupi, Alessandro Trinca, Marta Volonteri +2
Observations by the James Webb Space Telescope of the Universe at have shown that massive black holes (MBHs) appear extremely overmassive compared to the local correla…
Normal black holes in bulge-less galaxies: the largely quiescent, merger-free growth of black holes over cosmic time
G. Martin, S. Kaviraj, M. Volonteri +6
Understanding the processes that drive the formation of black holes (BHs) is a key topic in observational cosmology. While the observed -- corr…
Chasing the observational signatures of seed black holes at z > 7: candidate statistics
Rosa Valiante, Raffaella Schneider, Luca Graziani +1
Supermassive black holes (SMBHs) of 10^9-10^10 Msun were already in place ~13 Gyr ago, at z>6. Super-Eddington growth of low-mass BH seeds (~100 Msun) or less extreme accretion ont…
Gravitational Waves from the Remnants of the First Stars
Tilman Hartwig, Marta Volonteri, Volker Bromm +4
Gravitational waves (GWs) provide a revolutionary tool to investigate yet unobserved astrophysical objects. Especially the first stars, which are believed to be more massive than p…
Constraining the Spin of the Black Hole in Fairall 9 with Suzaku
S. Schmoll, J. M. Miller, M. Volonteri +6
We report on the results of spectral fits made to data obtained from a 168 ksec Suzaku observation of the Seyfert-1 galaxy Fairall 9. The source is clearly detected out to 30 keV.…
Evolution of massive black holes
Marta Volonteri
Supermassive black holes are nowadays believed to reside in most local galaxies. Accretion of gas and black hole mergers play a fundamental role in determining the two parameters d…
