Euclid: Discovery of 31 new quasars at
D. Yang, J. F. Hennawi, F. Guarneri +211
We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…
Euclid: A UV-faint quasar in a highly luminous star-forming host galaxy at
S. Belladitta, R. Decarli, E. Bañados +180
Constraining the co-evolution of supermassive black holes and their host galaxies in the first billion years after the Big Bang is essential for understanding the formation of the…
Dissecting the Obscured Core of GN20: an Active Galactic Nucleus Outshone by Young Stars
M. Hamed, L. Colina, P. G. Pérez-González +17
We investigate the relative contributions of star formation and AGN activity to the total energy budget of GN20, one of the most luminous dusty star-forming galaxies known at …
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…
A 6.2 Quasar on the Local M- Relation Quenching Its Host Galaxy from the Aether Survey
Weizhe Liu, Emanuele Paolo Farina, Xiaohui Fan +19
We report JWST/NIRSpec integral field unit (IFU) observations of the quasar J15124422 at from the Aether survey. At 900 Myr after the Big Bang, this object al…
Studying dark gaps in Ly- forest transmission with large reionization simulations
Barun Maity, Frederick B. Davies, Benedetta Spina +1
The physical conditions of the intergalactic medium (IGM) during the final stages of cosmic reionization () are not yet fully understood. Recent reports of unexpected…
