Angular momentum from tidal torques. [For galactic cluster evolution model]
The origin of the angular momentum of bound objects in large N-body simulations is studied using three sets of models. One model with white-noise initial conditions is analyzed as well as two inExpand
SPITZER QUASAR AND ULIRG EVOLUTION STUDY (QUEST). IV. COMPARISON OF 1 Jy ULTRALUMINOUS INFRARED GALAXIES WITH PALOMAR-GREEN QUASARS
We report the results from a comprehensive study of 74 ultraluminous infrared galaxies (ULIRGs) and 34 Palomar-Green (PG) quasars within z ~ 0.3 observed with the Spitzer Infrared Spectrograph (IRS).Expand
Transformations of Galaxies. II. Gasdynamics in Merging Disk Galaxies
In mergers of disk galaxies, gas plays a role quite out of proportion to its relatively modest contribution to the total mass. To study this behavior, we have included gasdynamics in self-consistentExpand
GOALS: The Great Observatories All-Sky LIRG Survey
ABSTRACT.The Great Observatories All-Sky LIRG Survey (GOALS20) combines data from NASA’s Spitzer Space Telescope, Chandra X-Ray Observatory, Hubble Space Telescope (HST), and Galaxy EvolutionExpand
Transformations of galaxies. I: Mergers of equal-mass stellar disks
This paper presents self-consistent numerical results for a small sample of merging encounters between equal-mass disk galaxies. These calculations illustrate how self-gravitating disks respond toExpand
Formation of gas discs in merging galaxies
Observations indicate that much of the interstellar gas in merging galaxies may settle into extended gaseous discs. Here, I present simulations of disc formation in mergers of gas-rich galaxies. UpExpand
GALAXY MERGERS AND THE MASS-METALLICITY RELATION: EVIDENCE FOR NUCLEAR METAL DILUTION AND FLATTENED GRADIENTS FROM NUMERICAL SIMULATIONS
Recent results comparing interacting galaxies to the mass-metallicity relation show that their nuclear oxygen abundances are unexpectedly low. We present analysis of N-body/smoothed-particleExpand
High-Resolution H I Mapping of NGC 4038/39 (“The Antennae”) and Its Tidal Dwarf Galaxy Candidates
We present new VLA C + D array H I observations and optical and near-infrared imaging of the well-known interacting system NGC 4038/39, "The Antennae." At low spatial resolution (similar to 40"), theExpand
A modified tree code: don't laugh; it runs
TLDR
We modify the Barnes-Hut tree algorithm by exploiting the fact that nearby particles tend to have very similar interaction lists. Expand
Encounters of disk/halo galaxies
The first numerical models of interacting galaxies are presented in which all dynamical components of the participants are modeled as fully three-dimensional N-body systems with thousands ofExpand
