Cosmic CARNage I: on the calibration of galaxy formation models

Alexander Knebe, Frazer R. Pearce, Violeta Gonzalez-Perez +31

We present a comparison of nine galaxy formation models, eight semi-analytical and one halo occupation distribution model, run on the same underlying cold dark matter simulation (c…

A Model for the Onset of Self-gravitation and Star Formation in Molecular Gas Governed by Galactic Forces: I. Cloud-scale Gas Motions

Sharon E. Meidt, Adam K. Leroy, Erik Rosolowsky +10

Modern extragalactic molecular gas surveys now reach the scales of star-forming giant molecular clouds (GMCs, 20-50 pc). Systematic variations in GMC properties with galaxy environ…

The origin of the diverse morphologies and kinematics of Milky Way-mass galaxies in the FIRE-2 simulations

Shea Garrison-Kimmel, Philip F. Hopkins, Andrew Wetzel +11

We use hydrodynamic cosmological zoom-in simulations from the FIRE project to explore the morphologies and kinematics of fifteen Milky Way (MW)-mass galaxies. Our sample ranges fro…

Copious Amounts of Dust and Gas in a z=7.5 Quasar Host Galaxy

Bram Venemans, Fabian Walter, Roberto Decarli +10

We present IRAM/NOEMA and JVLA observations of the quasar J1342+0928 at z=7.54 and report detections of copious amounts of dust and [CII] emission in the interstellar medium (ISM)…

Clumpy Galaxies in CANDELS. II. Physical Properties of UV-bright Clumps at

Yicheng Guo, Marc Rafelski, Eric F. Bell +20

Studying giant star-forming clumps in distant galaxies is important to understand galaxy formation and evolution. At present, however, observers and theorists have not reached a co…

Reconciling observed and simulated stellar halo masses

Robyn E. Sanderson, Shea Garrison-Kimmel, Andrew Wetzel +6

We use cosmological hydrodynamical simulations of Milky-Way-mass galaxies from the FIRE project to evaluate various strategies for estimating the mass of a galaxy's stellar halo fr…
