A first systematic study of [OIII] 88m at : two luminous oxygen lines and a powerful ionized outflow in the first 600 million years

Hiddo S. B. Algera, John R. Weaver, Tom J. L. C. Bakx +35

We present deep ALMA Band 7 observations of the [OIII] m line and underlying dust continuum emission in four UV-bright, gravitationally lensed (magnification ), JW…

A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy

Danielle A. Berg, Rohan P. Naidu, John Chisholm +18

We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…

Deep JWST spectroscopy of galaxies in a candidate ionized bubble at : probing reionization at pMpc scales with Ly emission

Lily Whitler, Daniel P. Stark, Charlotte A. Mason +5

Strong Ly emission observed from galaxies when the Universe is expected to be highly neutral is thought to trace large ionized regions that facilitate the transmission of Ly…

The Growth of Dust in Galaxies in the First Billion Years with Applications to Blue Monsters

Desika Narayanan, Paul Torrey, Daniel Stark +9

A combination of JWST observations at z~12-14 and ALMA observations of extremely dust-rich systems at z~6 has demonstrated that dust grows extremely fast in the early Universe, wit…

The AURORA Survey: High-Redshift Empirical Metallicity Calibrations from Electron Temperature Measurements at z=2-10

Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +29

We present detections of auroral emission lines of [OIII], [OII], [SIII], and [SII] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at from the AURORA su…

The AURORA Survey: Robust Helium Abundances at High Redshift Reveal A Subpopulation of Helium-Enhanced Galaxies in the Early Universe

Danielle A. Berg, Ryan L. Sanders, Alice E. Shapley +16

We present the first robust helium (He) abundance measurements in star-forming galaxies at redshifts using deep, moderate-resolution JWST/NIRSpec spectr…

The JWST Spectroscopic Properties of Galaxies at

Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +3

We characterize the JWST spectra of galaxies at , including newly-confirmed galaxies. We directly compare the spectroscopic properties against galaxie…

The Impact of Galaxy Overdensities and Ionized Bubbles on Ly Emission at

Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +4

Ly spectroscopy with JWST is opening a new window on the sizes of ionized bubbles through the reionization epoch. Theoretical expectations suggest typical bubble radii should be…

The AURORA Survey: The Evolution of Multi-phase Electron Densities at High Redshift

Michael W. Topping, Ryan L. Sanders, Alice E. Shapley +14

We present an analysis of deep /NIRSpec spectra of star-forming galaxies at , observed as part of the AURORA survey. We infer median low-ionization el…
