Difference between Dynamical Masses and Stellar Masses of the Bulge in Spiral Galaxies

This work aims to study the difference between bulge dynamical masses and bulge stellar masses for Spitzer/IRAC 3.6 μm images of 41spiral galaxies. The ratio between the stellar and dynamical masses

Theoretical investigation for the relation (supermassive black hole mass)–(spiral arm pitch angle): a correlation for galaxies with classical bulges

In this work, the determination of the masses of supermassive black holes (SMBHs) and the properties of their host spiral galaxies are focused for the purposes of constraining scaling relations and

Novel Relationship among Spiral Arm Pitch Angles (p) and momentum parameter of the host spiral galaxies

In this study, we have found a novel relationship among spiral arm pitch angles (p) and momentum parameter of the host spiral galaxies. In this study, we measured the momentum parameter for specimen

Inward Bound—The Search for Supermassive Black Holes in Galactic Nuclei

Dynamical searches reveal central dark objects with masses"" 106 to 109.5 M0 in the Galaxy, M31, M32, M87, NGC 3115, NGC 3377, NGC 4258, and NGC 4594. Indirect arguments suggest but do not prove that

Metastudy of the Spiral Structure of Our Home Galaxy

The current maps of the Milky Way disk still have large differences, much like early maps of the Earth's continents made in the 16th century had sizeable differences in the locations of continents

The structure of spiral galaxies — I. Near-infrared properties of bulges, discs and bars

We present data for a sample of 45 spiral galaxies over a range of Hubble types, imaged in the near-IR JK bands. Parameters are calculated describing the bulge, disc and bar K-band light

An Intermediate-Mass Black Hole in the Globular Cluster G1: Improved Significance from New Keck and Hubble Space Telescope Observations

We present dynamical models for the massive globular cluster G1. The goal is to measure or place a significant upper limit on the mass of any central black hole. Whether or not globular clusters
