Cold flow accretion into galaxies
The flow of gas from the cosmic web into galaxies provides the necessary fuel for star formation and galaxy assembly. I will review our current knowledge about...
COLDz: A High Space Density of Massive Dusty Starburst Galaxies ∼1 Billion Years after the Big Bang
We report the detection of CO(J = 2 → 1) emission from three massive dusty starburst galaxies at z > 5 through molecular line scans in the NSF's Karl G. Jansky...
Discovery of Four Apparently Cold Dusty Galaxies at z = 3.62─5.85 in the COSMOS Field: Direct Evidence of Cosmic Microwave Background Impact on High-redshift Galaxy Observables
We report Atacama Large Millimeter Array (ALMA) observations of four high-redshift dusty star-forming galaxy candidates selected from far-infrared (FIR)...
Dissecting local (U)LIRGs: A near-IR integral field spectroscopy perspective
The importance of Luminous and Ultraluminous infrared galaxies (U/LIRGs) in the context of the cosmological evolution of the star-formation has been well...
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted)...
Early-type galaxies: instructions to build them through mergers
Early-type galaxies: instructions to build them through mergers Massive early-type galaxies (ETGs) are "red and dead" systems mainly composed of old and metal...
Evolution of the Mass-Metallicity Relation from Redshift z ≈ 8 to the Local Universe
A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of...
Evolution of the Size–Mass Relation of Star-forming Galaxies Since z = 5.5 Revealed by CEERS
We combine deep imaging data from the CEERS early release JWST survey and Hubble Space Telescope imaging from CANDELS to examine the size–mass relation of star...
Expectations of the Size Evolution of Massive Galaxies at 3 ≤ z ≤ 6 from the TNG50 Simulation: The CEERS/JWST View
We present a catalog of about 25,000 images of massive (M ⋆ ≥ 10 9 M ⊙) galaxies at redshifts 3 ≤ z ≤ 6 from the TNG50 cosmological simulation, tailored for...
