Compaction and Quenching of High-z Galaxies in Cosmological Simulations: Blue and Red Nuggets
Adi Zolotov, Avishai Dekel, Nir Mandelker +7
We use cosmological simulations to study a characteristic evolution pattern of high redshift galaxies. Early, stream-fed, highly perturbed, gas-rich discs undergo phases of dissipa…
Clumpy Galaxies in CANDELS. I. The Definition of UV Clumps and the Fraction of Clumpy Galaxies at 0.5<z<3
Yicheng Guo, Henry C. Ferguson, Eric F. Bell +19
Although giant clumps of stars are crucial to galaxy formation and evolution, the most basic demographics of clumps are still uncertain, mainly because the definition of clumps has…
Star Formation and Clumps in Cosmological Galaxy Simulations with Radiation Pressure Feedback
Christopher E. Moody, Yicheng Guo, Nir Mandelker +5
Cosmological simulations of galaxies have typically produced too many stars at early times. We study the global and morphological effects of radiation pressure (RP) in eight pairs…
An analytic solution for the minimal bathtub toy model: challenges in the star-formation history of high-z galaxies
Avishai Dekel, Nir Mandelker
We study the minimal ``bathtub" toy model as an analytic tool for capturing key processes of galaxy evolution and identifying robust successes and challenges in reproducing observa…
