The ALMA REBELS Survey: Efficient Ly Transmission of UV-Bright z7 Galaxies from Large Velocity Offsets and Broad Line Widths

Ryan Endsley, Daniel P. Stark, Rychard J. Bouwens +19

Recent work has shown that UV-luminous reionization-era galaxies often exhibit strong Lyman-alpha emission despite being situated at redshifts where the IGM is thought to be substa…

Constraints on the intergalactic medium from JWST spectroscopy of Lyman-alpha damping wings in galaxies

Charlotte A. Mason, Zuyi Chen, Daniel P. Stark +3

JWST provides a unique dataset to study reionization's earliest stages, promising insights into the first galaxies. Many JWST/NIRSpec prism spectra reveal smooth Lyman-alpha breaks…

The ALMA REBELS Survey: The Dust-obscured Cosmic Star Formation Rate Density at Redshift 7

Hiddo Algera, Hanae Inami, Pascal Oesch +21

Cosmic dust is an essential component shaping both the evolution of galaxies and their observational signatures. How quickly dust builds up in the early Universe remains an open qu…

The MOSDEF-LRIS Survey: Connection between Galactic-scale Outflows and the Properties of ~2 star-forming Galaxies

Andrew Weldon, Naveen Reddy, Michael Topping +10

We investigate the conditions that facilitate galactic-scale outflows using a sample of 155 typical star-forming galaxies at ~2 drawn from the MOSFIRE Deep Evolution Field (MOSD…

Ly emission in galaxies at : new insight from JWST into the statistical distributions of Ly properties at the end of reionization

Mengtao Tang, Daniel P. Stark, Richard S. Ellis +22

JWST has recently sparked a new era of Ly spectroscopy, delivering the first measurements of the Ly escape fraction and velocity profile in typical galaxies at $z\simeq6-10…

JWST/NIRCam Observations of Stars and HII Regions in Galaxies: Properties of Star Forming Complexes on 150 pc Scales

Zuyi Chen, Daniel P. Stark, Ryan Endsley +3

The onset of the {\it JWST}-era provides a much-improved opportunity to characterize the resolved structure of early star forming systems. Previous {\it Spitzer} observations of $z…
