JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
E. Vanzella, A. Claeyssens, B. Welch +27
Star cluster formation in the early universe and their contribution to reionization remains to date largely unconstrained. Here we present JWST/NIRCam imaging of the most highly ma…
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…
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…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
RELICS: Small-scale Star Formation in Lensed Galaxies at
Brian Welch, Dan Coe, Adi Zitrin +13
Detailed observations of star forming galaxies at high redshift are critical to understand the formation and evolution of the earliest galaxies. Gravitational lensing provides an i…
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-…
Quenching in Cosmic Sheets: Tracing the Impact of Large Scale Structure Collapse on the Evolution of Dwarf Galaxies
Imad Pasha, Nir Mandelker, Frank C. van den Bosch +2
Dwarf galaxies are thought to quench primarily due to environmental processes most typically occurring in galaxy groups and clusters or around single, massive galaxies. However, at…
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…
