Large-scale Overdensity of Lyman Break Galaxies around the z = 6.3 Ultraluminous Quasar J0100 + 2802

The Astrophysical Journal
We study the environment of the z = 6.33 ultraluminous quasar SDSS J010013.02+280225.8 (J0100) to understand its association with large-scale structure.

Forecasting local primordial non-Gaussianities from UNIONS Lyman-break galaxies and Planck CMB lensing

Astronomy & Astrophysics
Context. Local primordial non-Gaussianities, characterized by the parameter fNLloc f NL loc $ f_{\mathrm{NL}}^{\mathrm{loc}} $ , provide a powerful window into the physics of inflation.

Improving Photometric Redshifts of Epoch of Reionization Galaxies: A New Empirical Transmission Curve with Neutral Hydrogen Damping Wing Lyα Absorption

The Astrophysical Journal Letters
We present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have shown a flux deficit at wavelengths just redward of the Lyman break, and ...

EPOCHS. II. The Ultraviolet Luminosity Function from 7.5 < z < 13.5 Using 180 arcmin2 of Deep, Blank Fields from the PEARLS Survey and Public JWST Data

The Astrophysical Journal
We present an analysis of the ultraviolet luminosity function (UV LF) and star formation rate density of distant galaxies (7.5 < z < 13.5) in the “blank” fields of the Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS) survey ...

Observational Biases on Rotation Curves from Integral Field Unit Data at Cosmic Noon

The Astrophysical Journal
Through studying rotation curves, which depict how the velocity of the stars and gas changes with distance from the center of a galaxy, it has been confirmed that dark matter dominates galaxies’ outer regions, as their rotation curve remains flat ...

The PANORAMIC Survey: Pure Parallel Wide Area Legacy Imaging with JWST/NIRCam

The Astrophysical Journal
We present the PANORAMIC survey, a pure parallel extragalactic imaging program with JWST/NIRCam observed during Cycle 1. The survey obtained ∼530 square arcmin of NIRCam imaging from 1–5 μ m, totaling ∼192 hr of science integration time.
