Supermassive Black Hole Feedback
, 2019 Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped by the energy injection from accreting supermassive black holes (SMBHs). However, it is unclear how

Rotating scalarized supermassive black holes
European Physical Journal C: Particles and FieldsIn this study, we investigate rotating black hole solutions within a scalar-Gauss–Bonnet gravity framework that incorporates a squared Gauss–Bonnet term. By employing a quadratic–exponential coupling function between the scalar field and the Gauss–Bonnet

Probing the formation of the seeds of supermassive black holes with gravitational waves
, 2018 The existence of black holes in the intermediate mass interval between one hundred and ten thousand solar masses, filling the gap between the stellar and the supermassive black holes is a key prediction to explain the origin of luminous QSOs at redshifts

Weighing supermassive black holes [PDF]
Nature Astronomy, 2018 A study suggests that the gas clouds in the vicinity of rapidly accreting supermassive black holes are distributed in a planar distribution, impacting the estimation of the mass of the black hole based on the motion of these clouds.

Massive and supermassive black holes in the contemporary and early Universe and problems in cosmology and astrophysics [PDF]
, 2017 We discuss recent astronomical data showing that the role of massive primordial black holes in the Universe is much more significant than previously thought, both for the present Universe and for redshifts of the order of 10.

Powerful jets from accreting black holes: evidence from the optical and infrared
, 2010 A common consequence of accretion onto black holes is the formation of powerful, relativistic jets that escape the system. In the case of supermassive black holes at the centres of galaxies this has been known for decades, but for stellar-mass black ...

Non-linearly scalarized supermassive black holes
European Physical Journal C: Particles and FieldsIn this study, we investigate a nonlinear mechanism driving the formation of scalarized rotating black holes within a scalar-Gauss–Bonnet gravity framework that includes an additional squared Gauss–Bonnet term.
