Dust in the Average Galaxy: Attenuation, Emission, and Opacity from

Caitlin M. Casey, Hollis B. Akins, Andrew J. Battisti +43

We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…

When Stars Mimic Monsters: Spectral Evidence for an Carinae-like Giant Eruption in SBS 0335052 E

Zixuan Peng, Crystal L. Martin, Jiamu Huang +7

SBS 0335052 E is an extremely low-metallicity () blue compact dwarf galaxy. An active galactic nucleus has been proposed to explain the broad H emissio…

An ultra-high-resolution map of (dark) matter

Diana Scognamiglio, Gavin Leroy, David Harvey +38

Ordinary matter-including particles such as protons and neutrons-accounts for only about one sixth of all matter in the Universe. The rest is dark matter, which does not emit or ab…

Galaxy Protoclusters as Drivers of Cosmic Reionization: I. Bubble Overlap at Redshift z ~ 7 in LAGER-z7OD1

Crystal L. Martin, Weida Hu, Isak G. B. Wold +17

Since the launch of JWST, the sample size of reionization-era Lyman-alpha-emitters (LAEs) has been steadily growing; yet inferences about the neutral hydrogen fraction in the inter…

Large-Scale Structure in COSMOS-Web: Tracing Galaxy Evolution in the Cosmic Web up to with the Largest JWST Survey

Hossein Hatamnia, Bahram Mobasher, Sina Taamoli +31

We present a reconstruction of the large-scale structure using the James Webb Space Telescope's (JWST) COSMOS-Web program to trace environmentally driven galaxy evolution up to $z\…

COSMOS-Web: MIRI Data Reduction and Number Counts at 7.7m using JWST

Santosh Harish, Jeyhan S. Kartaltepe, Daizhong Liu +19

The COSMOS-Web survey is the largest JWST Cycle 1 General Observer program covering a contiguous ~0.54 deg area with NIRCam imaging in four broad-band filters and a non-contigu…
