Conditions for Bar Formation in Bulgeless Disk Galaxies
Dajeong Jang, Woong-Tae Kim, Yun Hee Lee
While bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a su…
Searching for Nearby Diffuse Dwarf Galaxies in the COSMOS Field
Dongdong Shi, XianZhong Zheng, Zhizheng Pan +5
It remains challenging to systematically survey nearby diffuse dwarf galaxies and address the formation mechanism of this population distinguishing from regular ones. We carry out…
Physical Properties of Tidal Features of Interacting Disk Galaxies: Three-dimensional Self-consistent Models
Sang Hoon Oh, Woong-Tae Kim, Hyung Mok Lee
Using self-consistent three-dimensional (3D) N-body simulations, we investigate the physical properties of non-axisymmetric features in a disk galaxy created by a tidal interaction…
Dark Energy, Hyperbolic Cosecant Cardassian and Virial Collapse for Power-style Cardassian
Wen-Jie Tian
New work gathers in Chapter 6 and Chapter 7. Tthe Cardassian dynamical equations are introduced generally and logically under GF fluid scenario, together with the flowing process o…
The nature of the SDSS galaxies in various classes based on morphology, colour and spectral features -- I. Optical properties
Joon Hyeop Lee, Myung Gyoon Lee, Changbom Park +1
We present a comprehensive study of the nature of the SDSS galaxies divided into various classes based on their morphology, colour, and spectral features. The SDSS galaxies are cla…
Local rigidity in quaternionic hyperbolic space
Inkang Kim, Pierre Pansu
In this note, we study deformations of quaternionic hyperbolic lattices in larger quaternionic hyperbolic spaces and prove local rigidity results. On the other hand, surface groups…
