Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution
Sharon Lapiner, Avishai Dekel, Jonathan Freundlich +6
We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction' event when near a `golden' stellar mass of $\sim…
A Subgrid Turbulent Mean Field Dynamo Model for Cosmological Galaxy Formation Simulations
Yuankang Liu, Michael Kretschmer, Romain Teyssier
Magnetic fields have been included in cosmological simulations of galaxy formation only recently, due to advances in numerical techniques and a better understanding of the galaxy f…
On the origin of surprisingly cold gas discs in galaxies at high redshift
Michael Kretschmer, Avishai Dekel, Romain Teyssier
We address the puzzling observational indications for very "cold" galactic discs at redshifts , an epoch when discs are expected to be highly perturbed. Using a high-r…
Evaluating Galaxy Dynamical Masses From Kinematics and Jeans Equilibrium in Simulations
Michael Kretschmer, Avishai Dekel, Jonathan Freundlich +3
We provide prescriptions to evaluate the dynamical mass () of galaxies from kinematic measurements of stars or gas using analytic considerations and the VELA suite of…
Origin of Star-Forming Rings around Massive Centres in Massive Galaxies at
Avishai Dekel, Sharon Lapiner, Omri Ginzburg +9
Using analytic modeling and simulations, we address the origin of an abundance of star-forming, clumpy, extended gas rings about massive central bodies in massive galaxies at $z \!…
Rapid Filamentary Accretion as the Origin of Extended Thin Discs
Michael Kretschmer, Oscar Agertz, Romain Teyssier
Galactic outflows driven by stellar feedback are crucial for explaining the inefficiency of star formation in galaxies. Although strong feedback can promote the formation of galact…
