Molecular gas in radio galaxies in dense Mpc-scale environments at
G. Castignani, F. Combes, P. Salomé +4
We investigate the role of dense Mpc-scale environment in processing molecular gas in distant Low luminosity radio galaxies (LLRGs) in galaxy (proto-)clusters. We have selected wit…
Stellar Black Hole Binary Mergers in Open Clusters
S. Rastello, P. Amaro-Seoane, M. Arca-Sedda +3
In this paper we study the evolution of a primordial black hole binary (BHB) in a sample of over 1500 direct-summation body simulations of small-and intermediate-size isolated…
Formation of ultra-diffuse galaxies in the field and in galaxy groups
Fangzhou Jiang, Avishai Dekel, Jonathan Freundlich +4
We study ultra-diffuse galaxies (UDGs) in zoom in cosmological simulations, seeking the origin of UDGs in the field versus galaxy groups. We find that while field UDGs arise from d…
Black hole and neutron star mergers in galactic nuclei
Giacomo Fragione, Evgeni Grishin, Nathan W. C. Leigh +2
Nuclear star clusters surrounding supermassive black holes (SMBHs) in galactic nuclei contain large numbers of stars, black holes (BHs) and neutron stars (NSs), a fraction of which…
Molecular gas in radio galaxies at in (proto-)cluster environment
G. Castignani, F. Combes, P. Salomè +4
We investigate the role of the environment in processing molecular gas in radio galaxies (RGs). We observed five RGs at in dense Mpc-scale environment with the IRAM-30m…
Hypervelocity Stars from a Supermassive Black Hole-Intermediate-mass Black Hole binary
Alexander Rasskazov, Giacomo Fragione, Nathan W. C. Leigh +4
In this paper we consider a scenario where the currently observed hypervelocity stars in our Galaxy have been ejected from the Galactic center as a result of dynamical interactions…
