Bulges and discs in the local Universe. Linking the galaxy structure to star formation activity [PDF]
, 2016 We use a sample built on the SDSS DR7 catalogue and the bulge-disc decomposition of Simard et al. (2011, ApJS, 196, 11) to study how the bulge and disc components contribute to the parent galaxy’s star formation activity, by determining its position in ...

THE ALIGNMENT OF GALAXY STRUCTURES
The Astrophysical Journal, 2015 We analyzed the orientation of the sample of ACO galaxy clusters. We examined the alignment in a subsample of 1056 galaxy structures taken from the Panko–Flin (2006) Catalog with known BM morphological types. We were looking for a correlation between the orientation of the cluster and the positions of neighboring clusters.

THE STRUCTURE OF 2MASS GALAXY CLUSTERS [PDF]
The Astrophysical Journal, 2011 We use a sample of galaxies from the Two Micron All Sky Survey (2MASS) Extended Source Catalog to refine a matched filter method of finding galaxy clusters that takes into account each galaxy's position, magnitude, and redshift if available. The matched filter postulates a radial density profile, luminosity function, and line-of-sight velocity ...

The Evolution of Galaxy Structure Over Cosmic Time [PDF]
, 2014 I present a comprehensive review of the evolution of galaxy structure in the Universe from the first galaxies currently observable at z ∼ 6 down to galaxies observable in the local Universe.

Analytical Approximations to Galaxy Clustering [PDF]
, 1997 We discuss some recent progress in constructing analytic approximations to the galaxy clustering. We show that successful models can be constructed for the clustering of both dark matter and dark matter haloes.

Translators of Galaxy Morphology Indicators between Observation and Simulation
The Astrophysical Journal, 2023 Based on the recent advancements in numerical simulations of galaxy formation, we anticipate the achievement of realistic models of galaxies in the near future.

The Spiral Structure in the Solar Neighborhood
Frontiers in Astronomy and Space Sciences, 2021 The spiral structure in the solar neighborhood is an important issue in astronomy. In the past few years, there has been significant progress in observation. The distances for a large number of good spiral tracers, i.e., giant molecular clouds, high-mass

Orbital structure of triaxial galaxies [PDF]
Symposium - International Astronomical Union, 2004 We have developed a method to construct realistic triaxial dynamical models for elliptical galaxies, allowing us to derive best-fitting parameters, such as the mass-to-light ratio and the black hole mass, and to study the orbital structure. We use triaxial theoretical Abel models to investigate the robustness of the method.

Transformations of galaxies. III. Encounter dynamics and tidal response as functions of galaxy structure [PDF]
, 2015 Tidal interactions between disc galaxies depend on galaxy structure, but the details of this relationship are incompletely understood. I have constructed a three-parameter grid of bulge/disc/halo models broadly consistent with $\Lambda$CDM, and simulated
