Super-Eddington Accretion and Early-Stage Feedback in Ton S180
Pierpaolo Condò, Giacomo Venturi, Eleonora Parlanti +15
Narrow-line Seyfert 1 (NLSy1) galaxies are key laboratories for studying rapid supermassive black hole (SMBH) growth and active galactic nucleus (AGN) feedback at high accretion ra…
Emulating the complex galactic-scale orbital dynamics of LISA massive black hole pairs with normalizing flows
Pedro R. Capelo, Carlos Moreno Martinez, Nodens Koren +6
Massive black hole (MBH) pairs, formed in galaxy mergers, may coalesce in a burst of gravitational waves. Estimating the coalescence time-scales and rates is a long-standing astrop…
Exploring the Relationship Between Bars, Star Formation Activity, and Host Galaxy Properties from to
Eden Wise, Shardha Jogee, Yuchen Guo +20
We present the most comprehensive study to date of the relationship between bars, star formation, and galaxy properties from 0 to 2. We use a mass-complete sample…
The role of major mergers in triggering super-Eddington accretion
Riccardo Caleno, Tommaso Zana, Raffaella Schneider +6
JWST observations have opened a new era in the exploration of the high-redshift Universe, revealing black holes (BHs) with masses of several million solar masses already at ,…
Super-Eddington accretion in protogalactic cores
Tommaso Zana, Pedro R. Capelo, Mairo Boresta +6
The presence of massive black holes (BHs) exceeding already at redshift challenges standard models of BH growth. Super-Eddington (SE) accretion has…
Multi-wavelength properties of LISA detectable events
Srija Chakraborty, Simona Gallerani, Fabio Di Mascia +5
We investigate the intrinsic and observational properties of galaxies hosting coalescing massive black holes (MBHs) that gives rise to gravitational waves (GWs) detect…
Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe
Alessandro Trinca, Rosa Valiante, Raffaella Schneider +7
Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive co…
Is GN-z11 powered by a super-Eddington massive black hole?
Maulik Bhatt, Simona Gallerani, Andrea Ferrara +6
Observations of quasars powered by supermassive black holes (SMBHs; ) challenge our current understanding of early black hole (BH) f…
Are there more galaxies than we see around high- quasars?
Tommaso Zana, Stefano Carniani, David Prelogović +5
Whether or not quasars lie in the most massive dark-matter halos of the Universe is still a subject of dispute. While most theoretical studies support this scenario,…
Probing massive black holes with gravitational waves
Srija Chakraborty, Simona Gallerani, Tommaso Zana +6
We investigate the coalescence of massive black hole () binaries (MBHBs) at by adopting a suite of cosmological hydrodynamical simu…
The feedback of quasars on their galactic environment
Andrea Ferrara, Tommaso Zana, Simona Gallerani +1
Quasar outflows might either quench (negative) or enhance (positive feedback) star formation in galaxies located in the quasar environment. The possible outcome depends on 4 parame…
Bubbles and outflows: the novel JWST/NIRSpec view of the z=1.59 obscured quasar XID2028
Giovanni Cresci, Giulia Tozzi, Michele Perna +20
Quasar feedback in the form of powerful outflows is invoked as a key mechanism to quench star formation in galaxies, although direct observational evidence is still scarce and deba…
The black hole and host galaxy growth in an isolated QSO observed with ALMA
R. Tripodi, C. Feruglio, F. Fiore +11
The outstanding mass growth of supermassive black holes (SMBHs) at the Reionisation Epoch and how it is related to the concurrent growth of their host galaxies, poses challenges to…
Morphological decomposition of TNG50 galaxies: methodology and catalogue
Tommaso Zana, Alessandro Lupi, Matteo Bonetti +6
We present MORDOR (MORphological DecOmposeR, a new algorithm for structural decomposition of simulated galaxies based on stellar kinematics. The code measures the properties of up…
Feedback effect on the observable properties of AGN
Fabio Vito, Fabio Di Mascia, Simona Gallerani +4
Active galactic nuclei (AGN) feedback has a major impact onto the supermassive black-hole (SMBH) growth, the properties of the host galaxies, and their cosmic evolution. We investi…
Enhanced star formation in quasar companions
Tommaso Zana, Simona Gallerani, Stefano Carniani +5
Quasars powered by supermassive black holes (MBH, ) at are predicted to reside in cosmic over-dense regions. However, observations so far could not confi…
Disc instability and bar formation: view from the IllustrisTNG simulations
David Izquierdo-Villalba, Silvia Bonoli, Yetli Rosas-Guevara +7
