We study supermassive black holes (BHs) in merging galaxies, using a suite of hydrodynamical simulations with very high spatial (~10 pc) and temporal (~1 Myr) resolution, where we vary the initial…
The Pairing of Accreting Massive Black Holes in Multiphase Circumnuclear Disks: the Interplay Between Radiative Cooling, Star Formation, and Feedback Processes

We study the orbital decay of a pair of massive black holes (BHs) with masses and 107 , using hydrodynamical simulations of circumnuclear disks (CNDs) with the alternating presence of sub-grid…
Growing black holes and galaxies: black hole accretion versus star formation rate
- M. Volonteri, Pedro R. Capelo, H. Netzer, J. Bellovary, M. Dotti, F. Governato
- Physics
- 23 February 2015
We present a new suite of hydrodynamical simulations and use it to study, in detail, black hole and galaxy properties. The high time, spatial and mass resolution, and realistic orbits and mass…
Black hole accretion versus star formation rate: theory confronts observations
- M. Volonteri, Pedro R. Capelo, H. Netzer, J. Bellovary, M. Dotti, F. Governato
- Physics
- 25 February 2015
We use a suite of hydrodynamical simulations of galaxy mergers to compare star formation rate (SFR) and black hole accretion rate (BHAR) for galaxies before the interaction ('stochastic' phase),…
How robust are the constraints on cosmology and galaxy evolution from the lens-redshift test?
- Pedro R. Capelo, P. Natarajan
- Physics
- 22 May 2007
The redshift distribution of galaxy lenses in known gravitational lens systems provides a powerful test that can potentially discriminate amongst cosmological models. However, applications of this…
The polytropic approximation and X-ray scaling relations: constraints on gas and dark matter profiles for galaxy groups and clusters
- Pedro R. Capelo, P. Coppi, P. Natarajan
- Physics
- 23 November 2011
The X-ray properties of groups and clusters of galaxies obey scaling relations that provide insight into the physics of their formation and evolution. In this paper, we constrain gas and dark matter…
Black holes, gravitational waves and fundamental physics: a roadmap
- L. Barack, V. Cardoso, M. Zilhão
- PhysicsClassical and Quantum Gravity
- 14 June 2018
The grand challenges of contemporary fundamental physics—dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem—all involve gravity…
Nuclear coups: Dynamics of black holes in galaxy mergers
- S. V. Wassenhove, Pedro R. Capelo, F. Governato
- Physics
- 28 October 2013
We study the dynamical evolution of supermassive black holes (BHs) in merging galaxies on scales of hundreds of kpc to 10 pc, to identify the physical processes that aid or hinder the orbital decay…
A survey of dual active galactic nuclei in simulations of galaxy mergers: frequency and properties
- Pedro R. Capelo, M. Dotti, M. Volonteri, L. Mayer, J. Bellovary, S. Shen
- Physics
- 28 November 2016
We investigate the simultaneous triggering of active galactic nuclei (AGN) in merging galaxies, using a large suite of high-resolution hydrodynamical simulations. We compute dual-AGN observability…
Barred galaxies in cosmological zoom-in simulations: the importance of feedback
- T. Zana, Pedro R. Capelo, S. Shen
- PhysicsMonthly Notices of the Royal Astronomical Society
- 17 October 2018
Bars are a key factor in the long-term evolution of spiral galaxies, in their unique role in redistributing angular momentum and transporting gas and stars on large scales. The Eris-suite…
