CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm

Felix Martinez, Jeyhan S. Karaltepe, Andreas L. Faisst +52

We present the reduction and source catalogs for the \textit{COSMOS High- ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank fie…

COSMOS-3D: Diverse Environments and Hot-dust Signatures among Dusty Star-forming Galaxies at = 4.9-7.2

Siwei Zou, Manuel Aravena, Shaoze Geng +20

Dusty star-forming galaxies (DSFGs) are expected to trace early massive-halo assembly, but the connection between dust-obscured star formation, morphology, hot dust, and environmen…

Luminosity function of quasars at from SDSS and DESI

Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54

We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…

Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec

Xiangyu Jin, Jinyi Yang, Feige Wang +19

We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…

First-star imprints in a metal-poor galaxy overdensity near the end of reionization

Zihao Li, Koki Kakiichi, Lise Christensen +24

The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…

Extremely Metal-Poor Galaxies in DESI DR1: Connections to Galaxies in the Early Universe

Jipeng Sui, Hu Zou, Dirk Scholte +43

Extremely Metal-Poor Galaxies (XMPGs), defined as having metallicities below 10\% of the solar value, are considered possible local analogs to primordial systems and offer a unique…

ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization

Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42

We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
