TEMPLATES: Direct Abundance Constraints for Two Lensed Lyman-break Galaxies

The Astrophysical Journal
Using integrated spectra for two gravitationally lensed galaxies from the JWST TEMPLATES Early Release Science program, we analyze faint auroral lines, which provide direct measurements of the gas-phase chemical abundance.

Galaxy Ages with Redshift z = 2–4: Stellar Population Synthesis for Candidates in FourStar Galaxy Evolution Survey

The Astrophysical Journal
Observations of large amounts of massive galaxies with relatively old populations found at high redshifts are challenging galaxy formation scenarios within the standard cosmology.

The Star-forming Interstellar Medium of Lyman Break Galaxy Analogs [PDF]

The Astrophysical Journal, 2019
Abstract We present Very Large Telescope SINFONI near-infrared (NIR) integral field spectroscopy of six z ∼ 0.2 Lyman break galaxy “analogs” (LBAs) from which we detect H i, He i, and [Fe ii] recombination lines and multiple H2 rovibrational lines in emission.

The Parallel Ionizing Emissivity Survey (PIE). I. Survey Design and Selection of Candidate Lyman Continuum Leakers at 3.1 < z < 3.5

The Astrophysical Journal
We present the survey design and initial results from the Parallel Ionizing Emissivity (PIE) survey. PIE is a large Hubble Space Telescope survey designed to detect Lyman continuum (LyC) emitting galaxies at 3.1 < z < 3.5 and stack their images in order ...

Geometric Distortion of the Correlation Function of Lyman‐Break Galaxies [PDF]

The Astrophysical Journal, 1999
The number of galaxies with measured redshifts > 1 is at present rapidly increasing, allowing for measurements of their correlation function. The correlations function is measured in redshift space, as a function of angular separation and velocity difference.

Evidence of Extreme Ionization Conditions and Low Metallicity in GHZ2/GLASS-Z12 from a Combined Analysis of NIRSpec and MIRI Observations

The Astrophysical Journal
GHZ2/GLASS-z12, one of the most distant galaxies found in JWST observations, has been recently observed with both the NIRSpec and MIRI spectrographs, establishing a spectroscopic redshift z _spec = 12.34 and making it the first system at z > 10 with ...

Exploring the Mpc Environment of the Quasar ULAS J1342+0928 at z = 7.54

The Astrophysical Journal
Theoretical models predict that z ≳ 6 quasars are hosted in the most massive halos of the underlying dark matter distribution and thus would be immersed in protoclusters of galaxies. However, observations report inconclusive results. We investigate the 1.
