Rapid growth in a dual AGN during a gas-rich merger at z~4.5
Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15
The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…
Set them free: extending RAMCOAL to model massive black hole triplets in hydrodynamical simulations of galaxies
Kunyang Li, Ricarda S. Beckmann, Yohan Dubois +1
Massive black hole binaries (MBHBs), and the higher-order multiples produced by repeated galaxy mergers, spend part of their lives in dynamical regimes that cosmological simulation…
Pebbles to Gems: Intermediate-mass black holes in the first star clusters
Benedetta Mestichelli, Manuel Arca Sedda, Marta Volonteri +9
The rapid assembly of supermassive black holes (SMBHs) observed at requires efficient seeding mechanisms in the early Universe. Population III (Pop. III) star clusters…
ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization
Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42
We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
Multi-messenger and Multi-band Studies of Massive Black Holes: the Synergies Between LISA and SKAO
Pedro R. Capelo, Alberto Mangiagli, Lorenz Zwick +2
Depending on its mass, the same gas-embedded massive black hole (BH) binary can emit gravitational waves (GWs) in one or more bands (nHz and mHz) concurrently, along with electroma…
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 ,…
