The Magellanic Stream: Circumnavigating the Galaxy
Elena D'Onghia, Andrew J. Fox
The Magellanic Clouds are surrounded by an extended network of gaseous structures. Chief among these is the Magellanic Stream, an interwoven tail of filaments trailing the Clouds i…
Fossil Group Origins VII. Galaxy substructures in fossil systems
S. Zarattini, M. Girardi, J. A. L. Aguerri +9
Fossil groups are expected to be the final product of galaxy merging within galaxy groups. In simulations, they are predicted to assemble their mass at high redshift. This early fo…
Excitation of coupled stellar motions in the Galactic Disk by orbiting satellites
E. D'Onghia, P. Madau, C. Vera-Ciro +2
We use a set of high-resolution N-body simulations of the Galactic disk to study its interactions with the population of satellites predicted cosmologically. One simulation illustr…
A Versatile Family of Galactic Wind Models
Chad Bustard, Ellen G. Zweibel, Elena D'Onghia
We present a versatile family of model galactic outflows including non-uniform mass and energy source distributions, a gravitational potential from an extended mass source, and rad…
On the conservation of the vertical action on galactic disks
Carlos Vera-Ciro, Elena D'Onghia
We employ high-resolution N-body simulations of isolated spiral galaxy models, from low-amplitude, multi-armed galaxies to Milky Way-like disks, to estimate the vertical action of…
Disk-stability constraints on the number of arms in spiral galaxies
Elena D'Onghia
A model based on disk-stability criteria to determine the number of spiral arms of a general disk galaxy with an exponential disk, a bulge and a dark halo described by a Hernquist…
