Numerical simulations on the relative importance of starbursts and AGN in ultra-luminous infrared galaxies [PDF]
, 2005 We investigate the relative importance of starbursts and AGN in nuclear activities of ultra-luminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes.

Gravitational torques in spiral galaxies: gas accretion as a driving mechanism of galactic evolution [PDF]
, 2002 The distribution of gravitational torques and bar strengths in the local Universe is derived from a detailed study of 163 galaxies observed in the near-infrared. The results are compared with numerical models for spiral galaxy evolution. It is found that

Orbiting Circum-galactic Gas as a Signature of Cosmological Accretion [PDF]
, 2011 We use cosmological SPH simulations to study the kinematic signatures of cool gas accretion onto a pair of well-resolved galaxy halos. Cold-flow streams and gas-rich mergers produce a circum-galactic component of cool gas that generally orbits with high ...

On the Origin of the Galaxy Star-Formation-Rate Sequence: Evolution and Scatter [PDF]
, 2010 We use a semi-analytic model for disk galaxies to explore the origin of the time evolution and small scatter of the galaxy SFR sequence -- the tight correlation between star-formation rate (SFR) and stellar mass (M_star).

Core-collapse Supernova Explosions in Active Galactic Nucleus Accretion Disks
The Astrophysical Journal, 2023 Astrophysical events that occur in active galactic nucleus (AGN) disks are believed to differ significantly from the ordinary in the interstellar medium.

Counterrotating Stars in Simulated Galaxy Disks [PDF]
, 2013 Counterrotating stars in disk galaxies are a puzzling dynamical feature whose origin has been ascribed to either satellite accretion events or to disk instabilities triggered by deviations from axisymmetry.

Kinematical & Chemical Characteristics of the Thin and Thick Disks [PDF]
, 2008 I discuss how the chemical abundance distributions, kinematics and age distributions of stars in the thin and thick disks of the Galaxy can be used to decipher the merger history of the Milky Way, a typical large galaxy. The observational evidence points

An accretion disk laboratory in the Seyfert 1.9 galaxy NGC 2992 [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractOver twenty five years of X-ray observations of the Seyfert 1.9 galaxy NGC 2992 show that it is a promising test-bed for severely constraining accretion disk models. The previous interpretation of the historical activity of NGC 2992 in terms of the accretion disk slowly becoming dormant over many years and then ‘re-building’ itself is not ...
