Predicting the Properties of the Remnants of Dissipative Galaxy Mergers
M. Covington, A. Dekel, T. J. Cox +2
We construct a physically motivated model for predicting the properties of the remnants of gaseous galaxy mergers, given the properties of the progenitors and the orbit. The model…
The effect of galaxy mass ratio on merger--driven starbursts
T. J. Cox, Patrik Jonsson, Rachel S. Somerville +2
We employ numerical simulations of galaxy mergers to explore the effect of galaxy mass ratio on merger--driven starbursts. Our numerical simulations include radiative cooling of ga…
Scaling Relations of Spiral Galaxies
S. Courteau, A. A. Dutton, F. van den Bosch +4
We construct a large data set of global structural parameters for 1300 field and cluster spiral galaxies and explore the joint distribution of luminosity L, optical rotation veloci…
Constructing Merger Trees that Mimic N-Body Simulations
Eyal Neistein, Avishai Dekel
We present a simple and efficient empirical algorithm for constructing dark-matter halo merger trees that reproduce the distribution of trees in the Millennium cosmological -bod…
Gravitational Quenching in Massive Galaxies and Clusters by Clumpy Accretion
Avishai Dekel, Yuval Birnboim
We consider a simple gravitational-heating mechanism for the long-term quenching of cooling flows and star formation in massive dark-matter haloes hosting ellipticals and clusters.…
Star formation in AEGIS field galaxies since z=1.1 . Staged galaxy formation, and a model of mass-dependent gas exhaustion
K. G. Noeske, S. M. Faber, B. J. Weiner +11
We analyze star formation (SF) as a function of stellar mass (M_*) and redshift z in the All Wavelength Extended Groth Strip International Survey (AEGIS), for star-forming field ga…
Bursting and Quenching in Massive Galaxies without Major Mergers or AGNs
Yuval Birnboim, Avishai Dekel, Eyal Neistein
We simulate the buildup of galaxies by spherical gas accretion through dark matter haloes, subject to the development of virial shocks. We find that a uniform cosmological accretio…
