The History of Galaxies and Galaxy Number Counts [PDF]

open access: yes, 1997
(Abridged) A simple quantitative model is presented for the history of galaxies to explain galaxy number counts, redshift distributions and some other related observations. We first infer that irregular galaxies and the disks of spiral galaxies are young,

The Global Schmidt law in star forming galaxies [PDF]

open access: yes, 1997
Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to study the form of the global star formation law over the full ...

Barred Spiral Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1970
We point out some properties of barred spiral galaxies which are important for the theory of their formation and spiral structure, and describe some theoretical work on the dynamics of these systems.

Molecular Clouds in Spiral Galaxies [PDF]

open access: yesSymposium - 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.

NUMERICAL MODELLING OF GAS DYNAMIC STRUCTURES IN SPIRAL GALAXIES

open access: yesOdessa Astronomical Publications, 2013
Observations show that in the global morphology of spiral galaxies appear and form multi-scale features that are embedded in a complex complete picture of the galaxy.

MAGNETIC FIELDS IN A SAMPLE OF NEARBY SPIRAL GALAXIES [PDF]

open access: yes, 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.

Galactic Density and Evolution Based on the Virial Theorem, Energy Minimization, and Conservation of Angular Momentum

open access: yesGalaxies, 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.

Galaxy Formation by Galactic Magnetic Fields [PDF]

open access: yes, 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.
