Robust Ly forest constraints on reionization from semi-analytic galaxy formation models

Yuxiang Qin, J. Stuart B. Wyithe

The high-redshift Ly forest provides one of the most sensitive probes of the final stages of reionization, but its interpretation can depend on how the ionizing sources are mode…

The DORCHA suite: nature, nurture, and the phase space distribution of the Milky Way's high redshift progenitors today

Sreedhar Balu, Chris Power, Kris Walker +1

Where in the present-day Milky Way should we search for the remnants of its earliest stars? We address this question using the DORCHA (Gaelic for Dark; DUR-uh-khuh) suite: a set of…

Quantifying biases in stellar masses of JWST high-z quasar host galaxies caused by quasar subtraction

Sabrina Berger, Madeline A. Marshall, J. Stuart B. Wyithe +4

JWST has enabled dozens of high- quasar host galaxy detections. Many of these observations imply galaxies with black holes that are overmassive compared to their low- counter…

Galaxy-scale lens search in the PEARLS NEP TDF and CEERS JWST fields

Giovanni Ferrami, Nathan J. Adams, Lewi Westcott +14

We present four galaxy scale lenses discovered in two JWST blank-fields: the ~ 54 arcmin^2 of the PEARLS North-Ecliptic-Pole Time-Domain Field (NEP TDF) and in the ~ 90 arcmin^2 of…

JWSTs PEARLS: NIRCam imaging and NIRISS spectroscopy of a star-forming galaxy lensed into a near-Einstein Ring by a massive elliptical galaxy

Nathan J. Adams, Giovanni Ferrami, Lewi Westcott +30

We present the discovery, and initial lensing analysis, of a high-redshift galaxy-galaxy lensing system within the JWST-PEARLS/HST-TREASUREHUNT North Ecliptic Pole Time Domain Fiel…

JWST's PEARLS: A z=6 quasar in a train-wreck galaxy merger system

Madeline A. Marshall, Rogier A. Windhorst, Giovanni Ferrami +35

We present JWST NIRSpec integral field spectroscopy observations of the z=5.89 quasar NDWFS J1425+3254 from 0.6-5.3 microns, covering the rest-frame ultraviolet and optical at a sp…
