Galaxies, 2018 Spiral galaxies are spinning, internally densified objects. The Virial Theorem explains galactic rotation curves via its linkage of the rotation rate to the gravitational self-potential (Ug) and the moment of inertia of oblate spheroids.

IN-N-OUT: THE GAS CYCLE FROM DWARFS TO SPIRAL GALAXIES [PDF]
, 2015 We examine the scalings of galactic outflows with halo mass across a suite of 20 high-resolution cosmological zoom galaxy simulations covering halo masses in the range .

Mass of Spiral Galaxies by Means of a Maximum Disc Model
Universitas Scientiarum, 2018 Maximum disc mass models for a set of spiral galaxies from the Ursa Major Cluster are presented. We construct the models using the Hunther method and the particular solutions are chosen in such away that the circular velocities are adjusted very ...

MAGNETIC FIELDS IN A SAMPLE OF NEARBY SPIRAL GALAXIES [PDF]
, 2014 Both observations and modeling of magnetic fields in the diffuse interstellar gas of spiral galaxies are well developed, but the theory has been confronted with observations for only a handful of individual galaxies.

A Catalog of Photometric Redshift and the Distribution of Broad Galaxy Morphologies
Galaxies, 2018 We created a catalog of photometric redshift of ∼3,000,000 SDSS galaxies annotated by their broad morphology. The photometric redshift was optimized by testing and comparing several pattern recognition algorithms and variable selection strategies, and ...

THE BLACK HOLE MASS FUNCTION DERIVED FROM LOCAL SPIRAL GALAXIES [PDF]
, 2014 We present our determination of the nuclear supermassive black hole (SMBH) mass function for spiral galaxies in the local universe, established from a volume-limited sample consisting of a statistically complete collection of the brightest spiral ...

ULTRALIGHT SCALARS AND SPIRAL GALAXIES [PDF]
Modern Physics Letters A, 2001 We study some possible astrophysical implications of a very weakly coupled ultralight dilaton-type scalar field. Such a field may develop an (approximately stable) network of domain walls. The domain wall thickness is assumed to be comparable with the thickness of the luminous part of the spiral galaxies. The walls provide trapping for galactic matter.

Rectangular Spiral Galaxies are still hard
Computational Geometry, 2023 Spiral Galaxies is a pencil-and-paper puzzle played on a grid of unit squares: given a set of points called centers, the goal is to partition the grid into polyominoes such that each polyomino contains exactly one center and is 180° rotationally symmetric about its center.
