Feedback-Free Starbursts at Cosmic Dawn: Observable Predictions for JWST
Zhaozhou Li, Avishai Dekel, Kartick C. Sarkar +4
We extend the analysis of a physical model within the standard cosmology that robustly predicts a high star-formation efficiency (SFE) in massive galaxies at cosmic dawn due to fee…
Filaments of The Slime Mold Cosmic Web And How They Affect Galaxy Evolution
Farhanul Hasan, Joseph N. Burchett, Douglas Hellinger +7
We present a novel method for identifying cosmic web filaments using the IllustrisTNG (TNG100) cosmological simulations and investigate the impact of filaments on galaxies. We comp…
UV-Bright Star-Forming Clumps and Their Host Galaxies in UVCANDELS at 0.5 z 1
Alec Martin, Yicheng Guo, Xin Wang +32
Giant star-forming clumps are a prominent feature of star-forming galaxies (SFGs) and contain important clues on galaxy formation and evolution. However, basic demographics of clum…
Reaching for the stars -- JWST/NIRSpec spectroscopy of a lensed star candidate at
Lukas J. Furtak, Ashish K. Meena, Erik Zackrisson +31
We present JWST/NIRSpec observations of a highly magnified star candidate at a photometric redshift of , previously detected in JWST/NIRCam imaging of t…
The Halo21 Absorption Modeling Challenge: Lessons From "Observing" Synthetic Circumgalactic Absorption Spectra
Zachary Hafen, Sameer, Cameron Hummels +7
In the Halo21 absorption modeling challenge we generated synthetic absorption spectra of the circumgalactic medium (CGM), and attempted to estimate the metallicity, temperature, an…
The Evolving Effect Of Cosmic Web Environment On Galaxy Quenching
Farhanul Hasan, Joseph N. Burchett, Alyssa Abeyta +7
We investigate how cosmic web structures affect galaxy quenching in the IllustrisTNG (TNG100) cosmological simulations by reconstructing the cosmic web within each snapshot using t…
A cosmic stream of atomic carbon gas connected to a massive radio galaxy at redshift 3.8
Bjorn H. C. Emonts, Matthew D. Lehnert, Ilsang Yoon +7
The growth of galaxies in the early Universe is driven by accretion of circum- and inter-galactic gas. Simulations predict that steady streams of cold gas penetrate the dark matter…
The Extended [CII] under Construction? Observation of the brightest high-z lensed star-forming galaxy at z = 6.2
Yoshinobu Fudamoto, Akio K. Inoue, Dan Coe +26
We present results of [CII] emission line observations, and report the spectroscopic redshift confirmation of a strongly lensed () star-forming galaxy, MAC…
Efficient Formation of Massive Galaxies at Cosmic Dawn by Feedback-Free Starbursts
Avishai Dekel, Kartick S. Sarkar, Yuval Birnboim +2
JWST observations indicate a surprising excess of luminous galaxies at and above, consistent with efficient conversion of the accreted gas into stars, unlike the suppres…
