Star Formation in Normal Irregular Galaxies [PDF]

Symposium - International Astronomical Union, 1987
Normal, non-interacting irregular galaxies can be quite successful at forming stars. Therefore, spiral density waves are not necessary to a vigorous production of stars. Nevertheless, there is a large range in star-formation rates among irregular galaxies.

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 ...

FEAST: Probing the Stellar Population of the Starburst Dwarf Galaxy NGC 4449 with JWST/NIRCam

The Astrophysical Journal
We present new JWST/NIRCam observations of the starburst irregular galaxy NGC 4449, obtained in Cycle 1 as part of the Feedback in Emerging extrAgalactic Star clusTers program, which we use to investigate its resolved stellar populations and their ...

Constraining the Milky Way potential using the dynamical kinematic substructures

EPJ Web of Conferences, 2012
We present a method to constrain the potential of the non-axisymmetric components of the Galaxy using the kinematics of stars in the solar neighborhood. The basic premise is that dynamical substructures in phase-space (i.e.
