The imprint of dissipation on the shapes of merger remnant LOSVDs (2009)
Hoffman, Loren K., Cox, Thomas J., Dutta, Suvendra N., Hernquist, Lars E.
The properties of elliptical galaxies are broadly consistent with simulated remnants of gas-rich mergers between spirals, motivating more detailed studies of the imprint of this formation mechanism...
Dissipation and Extra Light in Galactic Nuclei: II. 'Cusp' Ellipticals (2008)
Hopkins, Philip F., Cox, Thomas J., Dutta, Suvendra N., Hernquist, Lars, Kormendy, John, Lauer, Tod R.
We study the origin and properties of 'extra' or 'excess' central light in the surface brightness profiles of cusp or power-law ellipticals. Dissipational mergers give rise to two-component profiles:...
Dissipation and Extra Light in Galactic Nuclei: I. Gas-Rich Merger Remnants (2008)
Hopkins, Philip F., Hernquist, Lars, Cox, Thomas J., Dutta, Suvendra N., Rothberg, Barry
We study the origin and properties of 'extra' or 'excess' central light in the surface brightness profiles of gas-rich merger remnants. Combining a large set of hydrodynamical simulations with data...
Kinematic Structure of Merger Remnants (2006)
Cox, T. J., Dutta, Suvendra N., Di Matteo, Tiziana, Hernquist, Lars, Hopkins, Philip F., Robertson, Brant, ...
We use numerical simulations to study the kinematic structure of remnants formed from mergers of equal-mass disk galaxies. In particular, we show that remnants of dissipational mergers, which include...
The kinematic structure of merger remnants (2006)
Cox, T. J., Dutta, Suvendra N., Di Matteo, Tiziana, Hernquist, Lars, Hopkins, Philip F., Robertson, Brant, ...
Substructure in Clusters of Galaxies and the value of ${\bf\Omega}$ (1995)
We investigate the formation of clusters of galaxies in an expanding universe using a new code that regrids at a region of high density. In particular we investigate two models for the initial...
