The JWST Emission Line Survey (JELS): Multi-wavelength properties of Paschen line-emitters at Cosmic Noon
Malte Brinch, Edo Ibar, Luis Ossa-Fuentes +14
Context: Narrowband JWST/NIRCam selection isolates star-forming galaxies in well-defined redshift slices, while ALMA and archival far-IR/submm data reveal obscured growth. We combi…
Constraining reionization-era Ly escape with JELS-MUSE: a highly complete H-selected sample at
A. L. Patrick, K. J. Duncan, Z. Li +16
The Ly escape fraction, , probes both the interstellar medium (ISM) conditions governing ionizing photon escape and the rising neutral fraction of the I…
The JWST Emission Line Survey (JELS): A narrow-band determination of the H Luminosity Function and Cosmic Star Formation into the Epoch of Reionization
C. A. Pirie, K. J. Duncan, P. N. Best +19
The recent star-formation activity in galaxies can be optimally traced by the H emission line, with the resulting H luminosity function (LF) at a given epoch providing a reli…
The DESI View of the Faint Radio Source Population in LoTSS DR2
M. I. Arnaudova, L. R. Holden, D. J. B. Smith +10
The faint radio-source population includes galaxies dominated by both star formation (SF) and active galactic nuclei (AGN), which are two key processes shaping galaxy evolution. To…
Unlocking the Full Potential of SKAO Extra-galactic Science with High-multiplex Optical Spectroscopy
Kenneth J Duncan, Natasha Maddox, Daniel J. B Smith +9
Parallel to the transformation in radio continuum and H I observations from SKAO pathfinders and precursors over the past decade has been the development of a new generation of mul…
Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys
Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25
We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…
Self-Consistent Direct Method for Chemical Abundances in High-z Galaxies with JWST
Karla Z. Arellano-Córdova, J. Eduardo Méndez-Delgado, Sophia R. Flury +10
The unprecedented rest-frame UV and optical coverage provided by JWST enables simultaneous constraints on the electron density (n) and temperature (T) of ionize…
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…
OutLines: Modeling Spectral Lines from Winds, Bubbles, and Outflows
Sophia R. Flury
Studies of kinematics and geometry of outflowing gas rely on modeling features in integrated spectra using empirical quantiles or fitting multiple Gaussian or Voigt profiles. Such…
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-…
Generalized ([OIII])-(HeI) Discrepancies in Ionized Nebulae: Possible Evidence of Case B Deviations and Temperature Inhomogeneities
J. E. Méndez-Delgado, E. D. Skillman, E. Aver +11
The physics of recombination lines (RLs) in the HeI singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the intensities of HeI singl…
