The Quest for Dual and Binary Supermassive Black Holes: A Multi-Messenger View
Alessandra De Rosa, Cristian Vignali, Tamara Bogdanović +27
The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-messenger era is compelling. Detecting dual active galactic nuclei (AGN) -- active SMBHs at…
Cosmological simulations of black hole growth II: how (in)significant are merger events for fuelling nuclear activity?
Lisa K. Steinborn, Michaela Hirschmann, Klaus Dolag +5
Which mechanism(s) are mainly driving nuclear activity in the centres of galaxies is a major unsettled question. In this study, we investigate the statistical relevance of galaxy m…
Pressure of the hot gas in simulations of galaxy clusters
S. Planelles, D. Fabjan, S. Borgani +11
We analyze the radial pressure profiles, the ICM clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in…
Origin and properties of dual and offset active galactic nuclei in a cosmological simulation at z=2
Lisa K. Steinborn, Klaus Dolag, Julia M. Comerford +3
In the last few years, it became possible to observationally resolve galaxies with two distinct nuclei in their centre. For separations smaller than 10kpc, dual and offset active g…
Neutral hydrogen in galaxy clusters: impact of AGN feedback and implications for intensity mapping
Francisco Villaescusa-Navarro, Susana Planelles, Stefano Borgani +8
By means of zoom-in hydrodynamic simulations we quantify the amount of neutral hydrogen (HI) hosted by groups and clusters of galaxies. Our simulations, which are based on an impro…
Connecting Angular Momentum and Galactic Dynamics: The complex Interplay between Spin, Mass, and Morphology
A. F. Teklu, R. -S. Remus, K. Dolag +5
The evolution and distribution of the angular momentum of dark matter (DM) halos have been discussed in several studies over the past decades. In particular, the idea arose that an…
A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
Lisa K. Steinborn, Klaus Dolag, Michaela Hirschmann +2
In large scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion onto black holes and AGN feedback are commonly used. Such models typically depend…
