We quantify the distribution of [O iii]+ H β line strengths at z≃ 7 using a sample of 20 bright
(≲–21) galaxies. We select these systems over wide-area fields (2.3 deg2 total) using a new …

Our understanding of reionization has advanced considerably over the past decade, with
several results now demonstrating that the intergalactic medium transitioned from …

Reionization-era galaxies tend to exhibit weak Ly α emission, likely reflecting attenuation
from an increasingly neutral IGM. Recent observations have begun to reveal exceptions to …

We report the first results from the Clusters Around Radio-Loud AGN program, a Cycle 7 and
8 Spitzer Space Telescope snapshot program to investigate the environments of a large …

The deflection angles of lensed sources increase with their distance behind a given lens.
We utilize this geometric effect to corroborate the z phot≃ 9.8 photometric redshift estimate of …

We have mapped the northern area (30'× 20') of a Local Group spiral galaxy M33 in 12 CO
(J= 1–0) line with the 45 m telescope at the Nobeyama Radio Observatory. Along with Hα …

We report on analysis using the JWST to identify a candidate progenitor star of the Type II-
plateau (II-P) supernova SN 2022acko in the nearby, barred spiral galaxy NGC 1300. To our …

ABSTRACT VLA 1.4 GHz (σ∼ 0.012 mJy) and MIPS 24 and 70 μm (σ∼ 0.02 and 1.7 mJy,
respectively) observations covering the 2 deg 2 COSMOS field are combined with an …

We use Chandra X-ray and Spitzer infrared (IR) observations to explore the active galactic
nucleus (AGN) and starburst populations of XMMXCS J2215. 9− 1738 at z= 1.46, one of the …

We present the results from ALMA CO (3–2) observations of 66 Hα-selected galaxies in
three protoclusters around radio galaxies: PKS 1138− 262 (= 2.16), USS 1558− 003 …
