Flat-Cored Dark Matter in Cuspy Clusters of Galaxies
Amr El-Zant, Yehuda Hoffman, Joel Primack +2
Sand, Treu, & Ellis (2002) have measured the central density profile of cluster MS2137-23 with gravitational lensing and velocity dispersion and removed the stellar contribution wi…

Long-Lived Double-Barred Galaxies: Critical Mass and Length Scales
Amr El-Zant, Isaac Shlosman
A substantial fraction of disk galaxies is double-barred. We analyze the dynamical stability of such nested bar systems by means of Liapunov exponents,by fixing a generic model and…

Galaxy Formation in Triaxial Halos: Black Hole-Bulge-Dark Halo Correlation
Amr El-Zant, Isaac Shlosman, Mitch Begelman +1
The masses of supermassive black holes (SBHs) show correlations with bulge properties in disk and elliptical galaxies. We study the formation of galactic structure within flat-core…
