HYPERION. The cold ISM of rapidly growing quasars: diverse gas reservoirs, dust enrichment, and feedback signatures
Claudia Maria Pierro, Roberta Tripodi, Laura Pentericci +11
Luminous QSOs at host some of the most rapidly assembled SMBHs in the early Universe. Characterizing their cold ISM is essential to determine their evolution. We investigate…
Unveiling the trends between dust attenuation and galaxy properties at z ~ 2 - 12 with the James Webb Space Telescope
V. Markov, S. Gallerani, A. Pallottini +7
A variety of dust attenuation/extinction curves have been observed in high-redshift galaxies, with mixed results regarding their correlations with global galaxy properties. These v…
Dust attenuation evolution in - JWST galaxies
V. Markov, S. Gallerani, A. Ferrara +5
A sizable fraction of the heavy elements synthesized by stars in galaxies condenses into sub-micron-sized solid-state particles, known as dust grains. Dust produces a wavelength-de…
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…
ALMA 360 pc high-frequency observations reveal warm dust in the center of a quasar
Romain A. Meyer, Fabian Walter, Fabio Di Mascia +3
The temperature of the cold dust in z>6 galaxies is a potential tracer of Active Galactic Nucleus (AGN) and stellar feedback, and is the dominant source of uncertainty in inferring…
Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr
Roberta Tripodi, Nicholas Martis, Vladan Markov +29
The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
