Galaxies: From Kinematics to Dynamics
Michael R. Merrifield
These lectures are intended to provide an introduction to the rich interplay between N-body simulations and stellar-kinematic observations of galaxies. The first section describes…
Explorations in Hubble Space: A Quantitative Tuning Fork
Roberto G. Abraham, Michael R. Merrifield
In order to establish an objective framework for studying galaxy morphology, we have developed a quantitative two-parameter description of galactic structure that maps closely on t…
The Origins of Disk Heating
M. R. Merrifield, J. Gerssen, K. Kuijken
By making spectral absorption-line observations of disk galaxies at intermediate inclinations, we have been able to determine the amplitude of their constituent stars' random motio…
X-Ray Wakes in Abell 160
Nick Drake, Michael R. Merrifield, Irini Sakelliou +1
`Wakes' of X-ray emission have now been detected trailing behind a few (at least seven) elliptical galaxies in clusters. To quantify how widespread this phenomenon is, and what its…
