Kinematics of Giant Low Surface Brightness Galaxies [PDF]

International Astronomical Union Colloquium, 1999
AbstractHigh sensitivity H I observations now exist for six giant low surface brightness (LSB) disk galaxies including the two prototypes, Malin 1 (Bothun et al. 1987; Impey & Bothun 1989) and F568-6 (also known as Malin 2; Bothun et al. 1990). Their H I surface brightnesses are generally low, but proportionally not as low as their optical surface ...

Handy Relation between Binary Black Hole Merger Times and Host Galaxy Properties

The Astrophysical Journal Letters
Over the past 15 yr, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of their host galaxy.

The Intrinsic Flattening of Galaxy Disks

The Astrophysical Journal
Highly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

Visit Nearby Halo Substructures Using LAMOST DR9 MRS Data

The Astrophysical Journal
Based on the LAMOST DR9 Medium Resolution Spectra (MRS) catalog, combined with astrometries from Gaia DR3, we conducted an investigation into the substructures in the stellar halo to obtain their chemical and kinematic information.

High-resolution Optical IFU Spectroscopy of the Complex Galaxy Merger II Zw 096

The Astrophysical Journal
Luminous and ultraluminous IR galaxies are critical for investigating feedback mechanisms due to a combination of intense star formation episodes and active galactic nuclei (AGN), particularly in the context of complex galaxy interactions.

A Stellar Dynamical Mass for the Central Black Hole in MCG–06-30-15

The Astrophysical Journal
We present the stellar dynamical (SD) mass of the central black hole in the nearby Seyfert galaxy MCG–06-30-15 using the Schwarzschild orbit-superposition method implemented in the open-source code FORSTAND .
