Resolving dust and Lyα emission in a lensed galaxy at the epoch of reionization with JWST/CANUCS

V. Markov, M. Bradač, V. Estrada-Carpenter +20

Lyman emission is highly sensitive to dust and neutral hydrogen and is therefore expected to be strongly suppressed in dusty or gas-rich galaxies during the epoch of reionizat…

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…

The mass-metallicity relation as a ruler for galaxy evolution: insights from the James Webb Space Telescope

A. Pallottini, A. Ferrara, S. Gallerani +5

Galaxy evolution emerges from the balance between cosmic gas accretion, fueling star formation, and supernova (SN) feedback, regulating the metal enrichment. Hence, the stellar mas…

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…

Primordial black holes as supermassive black holes seeds

Francesco Ziparo, Simona Gallerani, Andrea Ferrara

The presence of supermassive black holes (SMBHs, ) in the first cosmic Gyr () challenges current models of BH formation and evoluti…
