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…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
HYPERION. Shedding light on the first luminous quasars: A correlation between UV disc winds and X-ray continuum
A. Tortosa, L. Zappacosta, E. Piconcelli +41
One of the main open questions in the field of luminous () quasars (QSOs) at is the rapid formation (Gyr) of their superm…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla Bontà, B. M. Peterson, C. J. Grier +19
The goal of this project is to construct an estimator for the masses of supermassive black holes in active galactic nuclei (AGNs) based on the broad Halpha emission line. We make u…
Cyclostationary signals in LISA: a practical application to Milky Way satellites
Federico Pozzoli, Riccardo Buscicchio, Antoine Klein +3
One of the primary sources of gravitational waves (GWs) anticipated to be detected by the Laser Interferometer Space Antenna (LISA) are Galactic double white dwarf binaries (DWDs).…
Exploring Active Galactic Nuclei and Little Red Dots with the Obelisk simulation
M. Volonteri, M. Trebitsch, J. E. Greene +8
The James Webb Space telescope has discovered an abundant population of broad line emitters, typical signposts for Active Galactic Nuclei (AGN). Many of these sources have red colo…
