The nature of giant clumps in high-z discs: a deep-learning comparison of simulations and observations

Omri Ginzburg, Marc Huertas-Company, Avishai Dekel +4

We use deep learning to explore the nature of observed giant clumps in high-redshift disc galaxies, based on their identification and classification in cosmological simulations. Si…

IQ Collaboratory II: The Quiescent Fraction of Isolated, Low Mass Galaxies Across Simulations and Observations

Claire M Dickey, Tjitske K Starkenburg, Marla Geha +10

We compare three major large-scale hydrodynamical galaxy simulations (EAGLE, Illustris-TNG, and SIMBA) by forward modeling simulated galaxies into observational space and computing…

OVI Traces Photoionized Streams With Collisionally Ionized Boundaries in Cosmological Simulations of Massive Galaxies

Clayton Strawn, Santi Roca-Fàbrega, Nir Mandelker +6

We analyse the distribution and origin of OVI in the Circumgalactic Medium (CGM) of dark-matter haloes of M at in the VELA cosmological zoom-in simu…

Stellar Masses of Giant Clumps in CANDELS and Simulated Galaxies Using Machine Learning

M. Huertas-Company, Y. Guo, O. Ginzburg +12

A significant fraction of high redshift star-forming disc galaxies are known to host giant clumps, whose nature and role in galaxy evolution are yet to be understood. In this work…

Instability of Supersonic Cold Streams Feeding Galaxies IV: Survival of Radiatively Cooling Streams

Nir Mandelker, Daisuke Nagai, Han Aung +3

We study the effects of Kelvin Helmholtz Instability (KHI) on the cold streams that feed massive halos at high redshift, generalizing our earlier results to include the effects of…

Shattering of Cosmic Sheets due to Thermal Instabilities: a Formation Channel for Metal-Free Lyman Limit Systems

Nir Mandelker, Frank C. van den Bosch, Volker Springel +1

We present a new cosmological zoom-in simulation, where the zoom region consists of two halos with virial mass M_v~5x10^{12}M_{sun} and a ~Mpc long cosmic filament connecting them…
