Assessing Galaxy Rotation Kinematics: Insights from Convolutional Neural Networks on Velocity Variations

open access: yesUniverse
Distinguishing galaxies as either fast or slow rotators plays a vital role in understanding the processes behind galaxy formation and evolution. Standard techniques, which are based on the λR spin parameter obtained from stellar kinematics, frequently ...

Galactic Subsystems on the Basis of Cumulative Distribution of Space Velocities [PDF]

open access: yesSerbian Astronomical Journal, 2008
A sample containing $4,614$ stars with available space velocities and high-quality kinematical data from the Arihip Catalogue is formed. For the purpose of distinguishing galactic subsystems the cumulative distribution of space velocities is studied ...

Kinematic profiles of S0 galaxies

open access: yesThe Astronomical Journal, 1997
Stellar rotation curves, velocity dispersion profiles, and line-of-sight velocity distributions (LOSVD) as derived from absorption lines are presented for the major axes of 18 S0 and two elliptical galaxies. Ionized gas rotation curves and dispersions were measured from the [O III] 5007 Angstrom emission line in the 9 S0 galaxies displaying this ...

Investigating the Lower Limit of Metallicity for the Galactic Thin Disk

open access: yesThe Astrophysical Journal
We explore the metal-poor regime of the Galactic disk on the distribution of stars in the [ α /M]– V _ϕ plane, to identify the most metal-poor thin disk (MPTnD) stars belonging to the low- α sequence.

Dynamics of a Galaxy at z > 10 Explored by JWST Integral Field Spectroscopy: Hints of Rotating Disk Suggesting Weak Feedback

open access: yesThe Astrophysical Journal
We investigate the dynamics of GN-z11, a luminous galaxy at z = 10.60, carefully analyzing the public deep integral field spectroscopy (IFS) data taken with the JWST NIRSpec integral field unit.
