Bulge-Disk Decompositions and Structural Bimodality of Ursa Major Cluster Spiral Galaxies
Michael McDonald, Stephane Courteau, R. Brent Tully
We present bulge and disk (B/D) decompositions of existing K'-band surface brightness profiles for 65 Ursa Major cluster spiral galaxies. This improves upon the disk-only fits of T…
Scaling Relations and the Fundamental Line of the Local Group Dwarf Galaxies
Joanna Woo, Stephane Courteau, Avishai Dekel
We study the scaling relations between global properties of dwarf galaxies in the Local Group. In addition to quantifying the correlations between pairs of variables, we explore th…
An N-body/SPH Study of Isolated Galaxy Mass Density Profiles
Kelly Foyle, Stephane Courteau, Robert Thacker
We investigate the evolution of mass density profiles in secular disk galaxy models, paying special attention to the development of a two-component profile from a single initial ex…
Confronting Scaling Relations of Spiral Galaxies with Hierarchical Models of Disk Formation
Aaron A. Dutton, Stéphane Courteau
The scaling relations between rotation velocity, size and luminosity form a benchmark test for any theory of disk galaxy formation. We confront recent theoretical models of disk fo…
The Tully-Fisher Zero Point Problem
Aaron A. Dutton, Frank C. van den Bosch, Stéphane Courteau
A long standing problem for hierarchical disk galaxy formation models has been the simultaneous matching of the zero point of the Tully-Fisher relation and the galaxy luminosity fu…
