First direct dynamical detection of a dual supermassive black hole system at sub-kiloparsec separation
Karina. T. Voggel, Anil C. Seth, Holger Baumgardt +7
We investigated whether the two recently discovered nuclei in NGC7727 both host a super-massive black hole (SMBH). We used the high spatial resolution mode of the integral-field sp…
Supermassive black holes in cosmological simulations II: the AGN population and predictions for upcoming X-ray missions
Melanie Habouzit, Rachel S. Somerville, Yuan Li +13
In large-scale hydrodynamical cosmological simulations, the fate of massive galaxies is mainly dictated by the modeling of feedback from active galactic nuclei (AGN). The amount of…
The nucleation fraction of Local Volume galaxies
Nils Hoyer, Nadine Neumayer, Iskren Y. Georgiev +2
Nuclear star clusters (NSCs) are a common phenomenon in galaxy centres and are found in a vast majority of galaxies of intermediate stellar mass M. Recent invest…
ALMA Observations of the Sub-kpc Structure of the Host Galaxy of a z= 6.5 Lensed Quasar: A Rotationally-Supported Hyper-Starburst System at the Epoch of Reionization
Minghao Yue, Jinyi Yang, Xiaohui Fan +11
We report ALMA observations of the dust continuum and {\cii} emission of the host galaxy of J0439+1634, a gravitationally lensed quasar at . Gravitational lensing boosts the…
Are we observing a NSC in course of formation in the NGC 4654 galaxy?
Riccardo Schiavi, Roberto Capuzzo-Dolcetta, Iskren Y. Georgiev +2
We use direct -body simulations to explore some possible scenarios for the future evolution of two massive clusters observed toward the center of NGC\,4654, a spiral galaxy with…
