Evolution of local Ultraluminous mergers from NIR spectroscopy
K. M. Dasyra, L. J. Tacconi, R. I. Davies +4
We present results from our VLT Large Program to study the dynamical evolution of Ultraluminous Infrared Galaxies (ULIRGs). We have so far obtained near-infrared high-resolution IS…
Cosmological Simulations of Elliptical Galaxy Formation in LCDM and LWDM Cosmologies
Lisa J. Wright, Jeremiah P. Ostriker, Thorsten Naab +1
We present the results of a series of gas dynamical cosmological simulations of the formation of individual massive field galaxies in the standard concordance \LCDM and in a \LWDM…
Collisional Stellar Dynamics, Gas Dynamics and Special Purpose Computing
R. Spurzem, J. Makino, T. Fukushige +6
Challenging stellar dynamical problems, such as the study of gravothermal oscillations in star clusters, have in the past initiated the very successful building of GRAPE special pu…
Gas Dynamics and Inflow in gas-rich Galaxy Mergers
Thorsten Naab, Andreas Burkert
We performed N-body/SPH simulations of merging gas-rich disk galaxies with mass ratios of 1:1 and 3:1. A stellar disk and bulge component and a dark halo was realized with collisio…
Gas dynamics and disk formation in 3:1 mergers
Thorsten Naab, Andreas Burkert
We performed N-body/SPH simulations of merging gas rich disk-galaxies with a mass ratio of 3:1. A stellar disk and bulge component and a dark halo is realized with collisionless pa…
Evidence for Large Stellar Disks in Elliptical Galaxies
Andreas Burkert, Thorsten Naab
High-resolution numerical simulations of galaxy mergers are analysed. The global structure and isophotal shapes of the merger remnants are in good agreement with the observations.…
