Galaxy morphology classification: are stellar circularities enough? [PDF]
Serbian Astronomical JournalWe present a preliminary study exploring whether the stellar orbital circularity of simulated galaxies, available from precomputed catalogs in the IllustrisTNG project, can be used as a proxy for a broad morphological classification. We focus on

The Astrophysical Journal Supplement Series, 2023 By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H -band-selected massive galaxies in the COSMOS-DASH field, which includes 17,292 galaxies with stellar mass M _ ...

Stellar halo constraints on simulated late-type galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 How do late-type spiral galaxies form within the context of a cold dark matter cosmology? We contrast N-body, smoothed particle hydrodynamical simulations of galaxy formation that employ two different supernova feedback mechanisms. Observed mass and metallicity distributions of the stellar haloes of the Milky Way and M31 provide constraints on these ...

Galaxy Dynamics from Edge-On Late-type Galaxies
, 1999 We present first results of a program to study the dynamics of undisturbed bulgeless, low surface density disk galaxies in order to probe the underlying structure of dark matter halos. High resolution H-alpha rotation curves are combined with optical and infrared imaging to place strong limits on the halo profiles.

Understanding the Fundamental Plane and the Tully Fisher Relation
Frontiers in Astronomy and Space Sciences, 2020 The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.

Generalizations of the Tully‐Fisher Relation for Early‐ and Late‐Type Galaxies [PDF]
The Astrophysical Journal, 2007 We study the locus of dwarf and giant early and late-type galaxies on the Tully-Fisher relation (TFR), the stellar mass Tully-Fisher relation (sTFR) and the so-called baryonic or HI gas+stellar mass Tully-Fisher relation (gsTFR). We show that early-type and late-type galaxies, from dwarfs to giants, trace different yet approximately parallel TFRs ...

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
The Astrophysical Journal, 2023 Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.
