EMPRESS. XII. Statistics on the Dynamics and Gas Mass Fraction of Extremely Metal-poor Galaxies

The Astrophysical Journal
We  present the demography of the dynamics and gas mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of 0.015–0.195 Z _⊙ and low stellar masses of 10 ^4 –10 ^8 M _⊙ in the local universe.

The Effects of Bar Strength and Kinematics on Galaxy Evolution: Slow Strong Bars Affect Their Hosts the Most

The Astrophysical Journal
We study how bar strength and bar kinematics affect star formation in different regions of the bar by creating radial profiles of EW[H α ] and D _n 4000 using data from Sloan Digital Sky Survey-IV Mapping Nearby Galaxies at Apache Point Observatory ...

The Kinematic Signature of the Warp and Waves in the Milky Way Disk

The Astrophysical Journal
Using over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar V _Z as a function of L _Z (or R _g ) across different ϕ bins for various disk populations.

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

Universe
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 ...

IllustrisTNG in the HSC-SSP: No Shortage of Thin Disk Galaxies in TNG50

The Astrophysical Journal
We perform a thorough analysis of the projected shapes of nearby galaxies in both observations and cosmological simulations. We implement a forward-modeling approach to overcome the limitations in previous studies, which hinder accurate comparisons ...
