Not-so-little Red Dots: Two Massive and Dusty Starbursts at z ∼ 5–7 Pushing the Limits of Star Formation Discovered by JWST in the COSMOS-Web Survey

The Astrophysical Journal Letters
We present the properties of two candidate massive ( M _⋆ ∼ 10 ^11 M _⊙ ) and dusty ( A _v > 2.5 mag) galaxies at z = 5–7 in the first 0.28 deg ^2 of the COSMOS-Web survey. One object is spectroscopically confirmed at z _spec = 5.051, while the other has

Lyman Break Galaxies and Luminous IR Galaxies at z ~ 1

, 2007
We use deep GALEX images of CDFS in UV to define the first large sample of 420 Lyman Break Galaxies at z~1. We use a PSF fitting to estimate UV magnitudes on these deep crowded images. Deep Spitzer IRAC and MIPS provide the first detection of a large sample of Lyman Break Galaxies in the mid- to far-infrared range.

LATIS: Constraints on the Galaxy–Halo Connection at z ∼ 2.5 from Galaxy–Galaxy and Galaxy–Lyα Clustering

The Astrophysical Journal
The connection between galaxies and dark matter halos is often quantified using the stellar mass–halo mass (SMHM) relation. Optical and near-infrared imaging surveys have led to a broadly consistent picture of the evolving SMHM relation based on ...

EPOCHS. IV. SED Modeling Assumptions and Their Impact on the Stellar Mass Function at 6.5 ≤ z ≤ 13.5 Using PEARLS and Public JWST Observations

The Astrophysical Journal
We utilize deep JWST Near Infrared Camera (NIRCam) observations for the first direct constraints on the Galaxy Stellar Mass Function (GSMF) at z > 10.

Quantifying the Impact of LSST u-band Survey Strategy on Photometric Redshift Estimation and the Detection of Lyman-break Galaxies

The Astrophysical Journal Supplement Series
The Vera C. Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST), promising to discover billions of galaxies out to redshift 7, using six photometric bands ( ugrizy ) spanning the near-ultraviolet to the near-infrared.

EPOCHS. I. The Discovery and Star-forming Properties of Galaxies in the Epoch of Reionization at 6.5 < z < 18 with PEARLS and Public JWST Data

The Astrophysical Journal
We present in this paper the discovery, properties, and a catalog of 1165 high-redshift 6.5  12 in our sample and describe their properties. Finally, we note a significant observed excess of galaxies compared to models at z  > 12, revealing a tension ...

The Burstiness of Star Formation at z ∼ 6: A Huge Diversity in the Recent Star Formation Histories of Very UV-faint Galaxies

The Astrophysical Journal
IRAC data have long implied that early ( z  ≳ 6) galaxies often have very high specific star formation rates (sSFRs ≳ 30 Gyr ^−1 ), but JWST data have shown that at least some early galaxies are forming stars far less vigorously.
