The evolution of obscured AGN across cosmic time -- A large quasar survey for the 2040s

Tanya Urrutia, Darshan Kakkad, Paula Sánchez-Sáez +21

We propose a large quasar demographic optical multi-object spectroscopic (MOS) survey targeting over 50 million AGN candidates up to the highest redshifts possible in the optical (…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Northern Local Star-forming Dwarf Galaxies. Analogues of the First Galaxies and Probes of the Cosmic Metallicity Scale

C. Esteban, J. M. Vilchez, J. García-Rojas +15

Star-forming dwarf galaxies in the local Universe, especially extremely metal-poor ones, can be considered analogous to early galaxies of the Epoch of Reionization (z >= 6). Curren…

The JWST Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization

H. M. O. Stephenson, J. P. Stott, C. A. Pirie +18

We used observations from the JWST Emission Line Survey (JELS) to measure the half-light radii () of 23 H-emitting star-forming (SF) galaxies at in the PRIMER/COS…

Feedback and dynamical masses in high- galaxies: the advent of high-resolution NIRSpec spectroscopy

A. Saldana-Lopez, J. Chisholm, S. Gazagnes +11

Stellar feedback is an essential step in the baryon cycle of galaxies, but it remains unconstrained beyond Cosmic Noon. We study the ionized gas kinematics, dynamical mass and gas-…
