Witnessing the star-formation quenching in ellipticals
Suraj Dhiwar, Kanak Saha, Avishai Dekel +4
We study the evolution of elliptical galaxies in the color-magnitude diagram in terms of their star-formation history and environment, in an attempt to learn about their qu…
CEERS Key Paper I: An Early Look into the First 500 Myr of Galaxy Formation with JWST
Steven L. Finkelstein, Micaela B. Bagley, Henry C. Ferguson +64
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets g…
CEERS Key Paper V: A triality on the nature of HST-dark galaxies
Pablo G. Pérez-González, Guillermo Barro, Marianna Annunziatella +52
The new capabilities that JWST offers in the near- and mid-infrared (IR) are used to investigate in unprecedented detail the nature of optical/near-IR faint, mid-IR bright sources,…
From starburst to quenching: merger-driven evolution of the star formation regimes in a shell galaxy
Jonathan Petersson, Florent Renaud, Oscar Agertz +2
Shell galaxies make a class of tidally distorted galaxies, characterised by wide concentric arc(s), extending out to large galactocentric distances with sharp outer edges. Recent o…
Effects of feedback on galaxies in the VELA simulations: elongation, clumps and compaction
Daniel Ceverino, Nir Mandelker, Gregory F. Snyder +5
The evolution of star-forming galaxies at high redshifts is very sensitive to the strength and nature of stellar feedback. Using two sets of cosmological, zoom-in simulations from…
Optimized Photometric Redshifts for the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS)
Dritan Kodra, Brett H. Andrews, Jeffrey A. Newman +27
We present the first comprehensive release of photometric redshifts (photo-z's) from the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) team. We use stati…
RC100: Rotation Curves of 100 Massive Star-Forming Galaxies at z=0.6-2.5 Reveal Little Dark Matter on Galactic Scales
A. Nestor Shachar, S. H. Price, N. M. Förster Schreiber +19
We analyze Ha or CO rotation curves (RCs) extending out to several galaxy effective radii for 100 massive, large, star-forming disk galaxies (SFGs) across the peak of cosmic galaxy…
Conditions for Clump Survival in High-z Disc Galaxies
Avishai Dekel, Offek Tziperman, Kartick Sarkar +4
We study the survival versus disruption of the giant clumps in high-redshift disc galaxies, short-lived (S) versus long-lived (L) clumps and two L sub-types, via analytic modeling…
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121
Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…
A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ~ 12 Galaxy in Early JWST CEERS Imaging
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +117
We report the discovery of a candidate galaxy with a photo-z of z~12 in the first epoch of the JWST Cosmic Evolution Early Release Science (CEERS) Survey. Following conservative se…
The Response of Dark Matter Haloes to Gas Ejection: CuspCore II
Zhaozhou Li, Avishai Dekel, Nir Mandelker +2
We propose an analytic model, CuspCore II, for the response of dark matter (DM) haloes to central gas ejection, as a mechanism for generating DM-deficient cores in dwarfs and high-…
The evolution of turbulent galactic discs: gravitational instability, feedback and accretion
Omri Ginzburg, Avishai Dekel, Nir Mandelker +1
We study the driving of turbulence in star-froming disc galaxies of different masses at different epochs, using an analytic "bathtub" model. The disc of gas and stars is assumed to…
