Molecular Clouds in Spiral Galaxies [PDF]
Symposium - International Astronomical Union, 1983 A large observational program investigating the 2.6 mm CO line in spiral galaxies is being conducted by myself and Nick Scoville using the 14 m telescope of the Five College Radio Astronomy Observatory (HPBW = 50″). Thus far we have observed 46 galaxies of types Sa, Sb, Sc and Irr, detected 31, and mapped 16.

Galaxy Formation by Galactic Magnetic Fields [PDF]
, 1999 Galaxies exhibit a sequence of various morphological types, i.e., the Hubble sequence, and they are basically composed of spheroidal components (elliptical galaxies and bulges in spiral galaxies) and disks.

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 ...

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 ...

Uncovering Spiral Structure in Flocculent Galaxies [PDF]
, 1996 We present K'(2.1 micron) observations of four nearby flocculent spirals, which clearly show low-level spiral structure and suggest that kiloparsec-scale spiral structure is more prevalent in flocculent spirals than previously supposed.

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 ...

Assembling Spiral Galaxies [PDF]
Symposium - International Astronomical Union, 1996 Nearby spiral galaxies offer vital clues to some of the most fundamental questions about galaxy formation and evolution: What is the star formation history of the universe, past and future? When did disks form, during the final stages of a single primeval collapse, or as a continuous or episodic process?

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.
