The origin of type-I profiles in cluster lenticulars: An interplay between ram pressure stripping and tidally-induced spiral migration
Adam J. Clarke, Victor P. Debattista, Rok Roškar +1
Using -body+SPH simulations of galaxies falling into a cluster, we study the evolution of their radial density profiles. When evolved in isolation, galaxies develop a type~II (d…
Orbital Decay of Supermassive Black Hole Binaries in Clumpy Multiphase Merger Remnants
R. Roškar, L. Mayer, D. Fiacconi +3
We simulate an equal-mass merger of two Milky Way-size galaxy discs with moderate gas fractions at parsec-scale resolution including a new model for radiative cooling and heating i…
A Systematic Look at the Effects of Radiative Feedback on Disc Galaxy Formation
Rok Roškar, Romain Teyssier, Oscar Agertz +2
Galaxy formation models and simulations rely on various feedback mechanisms to reproduce the observed baryonic scaling relations and galaxy morphologies. Although dwarf galaxy and…
MaGICC Thick Disk I: Comparing a Simulated Disk Formed with Stellar Feedback to the Milky Way
G. S. Stinson, J. Bovy, H. -W. Rix +7
We analyse the structure and chemical enrichment of a Milky Way-like galaxy with a stellar mass of 2 10^{10} M_sun, formed in a cosmological hydrodynamical simulation. It is disk-d…
The Effects of Radial Migration on the Vertical Structure of Galactic Discs
Rok Roškar, Victor P. Debattista, Sarah R. Loebman
We present evidence that isolated growing discs, subject to internal spiral perturbations, thicken due to both heating \emph{and} radial migration. We show this by demonstrating th…
The collapse of protoplanetary clumps formed through disc instability: 3D simulations of the pre-dissociation phase
M. Galvagni, T. Hayfield, A. C. Boley +3
We present 3D smoothed particle hydrodynamics simulations of the collapse of clumps formed through gravitational instability in the outer part of a protoplanetary disc. The initial…
