Galaxy collisions - dawn of a new era
The study of colliding galaxies has progressed rapidly in the last few years, driven by observations with powerful new ground- and space-based instruments. These instruments have been used for
Tides in colliding galaxies
Long tails and streams of stars are the most noticeable traces of galaxy collisions. However, their tidal origin was recognized only less than 50 years ago and more than 10 years after their first
Star formation triggered by galaxy interactions in modified gravity
Together with interstellar turbulence, gravitation is one key player in star formation. It acts both at galactic scales in the assembly of gas into dense clouds, and inside those structures for their
Slowly breaking waves: the longevity of tidally induced spiral structure
We have discovered long-lived waves in two sets of numerical models of fast (marginally bound or unbound) flyby galaxy collisions, carried out independently with two different codes. In neither
Models of the Morphology, Kinematics, and Star Formation History of the Prototypical Collisional Starburst System NGC 7714/7715 = ARP 284
We present new N-body, hydrodynamical simulations of the interaction between the starburst galaxy NGC 7714 and its poststarburst companion NGC 7715, focusing on the formation of the collisional
The symmetries and scaling of tidal tails in galaxies
We present analytic models for the formation and evolution of tidal tails and related structures following single or multiple impulsive disturbances in galaxy collisions. Since the epicyclic
Kinematics and physical properties of southern interacting galaxies: the minor merger AM 2306–721
We present an observational study about the effects of the interactions in the kinematics, stellar population and abundances of the components of the galaxy pair AM 2306-721. Rotation curves for the
Models of multicomponent splash bridges in face-on galaxy disc collisions
We use an inelastic particle code with shocks and cooling calculated on a subgrid level to study the gas in direct collisions between galaxy discs. The interstellar media (ISM) of the discs are
A Pipeline for Constructing a Catalog of Multi-method Models of Interacting Galaxies
A PIPELINE FOR CONSTRUCTING A CATALOG OF MULTI-METHOD MODELS OF INTERACTING GALAXIES Anthony Holincheck, PhD George Mason University, 2013 Dissertation Director: Dr. John Wallin Galaxies represent a
Head-on Collision of Disk–Sphere Galaxies
Numerical simulations are performed to study the tidal effects of non-merging rapid head-on collision between a disk galaxy and a spherical galaxy. The disk consists of three components – a disk, a
