Grand Design versus Multiarmed Spiral Galaxies: Dependence on Galaxy Structure

The Astronomical Journal
We developed an algorithm to use Galaxy Zoo 3D spiral arm masks produced by citizen scientist volunteers to semiautomatically classify spiral galaxies as either multiarmed or grand design spirals. Our final sample consists of 299 multiarmed and 245 grand

Forces Attributed to Dark Matter May Originate from Entangled Particles as Seen in the Shape Of Galaxies Formed by Grbs

International Journal of Engineering and Management Sciences, 2018
Recently, it has been suggested that entangled particles may be connected by a wormhole. If that is right, what is the distance between them we have to take into account when applying Newton's law of universal gravitation to these particles?

Dynamically Driven Evolution of the Interstellar Medium in M51 [PDF]

, 2009
Massive star formation occurs in giant molecular clouds (GMCs); an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the highest-fidelity observations of the grand-design spiral

Radio Jet Feedback on the Inner Disk of Virgo Spiral Galaxy Messier 58

The Astrophysical Journal
Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H _2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud active galactic nucleus (AGN). The inner 2.6 kpc of the galaxy appears to be overrun by shocks from

Modeling the Radial Color Profile of M31

Open Astronomy, 2003
We present a preliminary study of a fragment of the radial color profile of the spiral galaxy M 31 in terms of 2-D model accounting for internal extinction in the disk. The two stellar population disk model was assumed.
