CGM properties in VELA and NIHAO simulations; the OVI ionization mechanism: dependence on redshift, halo mass and radius
S. Roca-Fàbrega, A. Dekel, Y. Faerman +8
We study the components of cool and warm/hot gas in the circumgalactic medium (CGM) of simulated galaxies and address the relative production of OVI by photoionization versus colli…
The evolution of galaxy shapes in CANDELS: from prolate to oblate
Haowen Zhang, Joel R. Primack, S. M. Faber +9
We model the projected b/a-log a distributions of CANDELS main sequence star-forming galaxies, where a (b) is the semi-major (semi-minor) axis of the galaxy images. We find that sm…
Dark Matter Halo Properties vs. Local Density and Cosmic Web Location
Tze Goh, Joel Primack, Christoph T. Lee +6
We study the effects of the local environmental density and the cosmic web environment (filaments, walls, and voids) on key properties of dark matter halos using the Bolshoi-Planck…
Deep Learning Identifies High-z Galaxies in a Central Blue Nugget Phase in a Characteristic Mass Range
M. Huertas-Company, J. R. Primack, A. Dekel +11
We use machine learning to identify in color images of high-redshift galaxies an astrophysical phenomenon predicted by cosmological simulations. This phenomenon, called the blue nu…
Is the dark-matter halo spin a predictor of galaxy spin and size?
Fangzhou Jiang, Avishai Dekel, Omer Kneller +8
The similarity between the distributions of spins for galaxies () and for dark-matter haloes (), indicated both by simulations and observations, is naively in…
A catalog of polychromatic bulge-disk decompositions of ~ 17.600 galaxies in CANDELS
Paola Dimauro, Marc Huertas-Company, Emanuele Daddi +20
Understanding how bulges grow in galaxies is critical step towards unveiling the link between galaxy morphology and star-formation. To do so, it is necessary to decompose large sam…
