Interstellar gas motions around massive star formation regions in the nearby dwarf galaxy DDO43
Acta PolytechnicaAreas of massive star formation are strongly influenced by stellar winds and supernovae, therefore, enhanced turbulent flows are expected. We analyse high-quality Karl G. Jansky Very Large Array observations of the neutral hydrogen gas content of DDO43,

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.

A Luminous X-Ray Active Galactic Nucleus in the Dwarf–Dwarf Galaxy Merger RGG 66
The Astrophysical JournalWe present the discovery of a luminous X-ray active galactic nucleus (AGN) in the dwarf galaxy merger RGG 66. The black hole is predicted to have a mass of M _BH ∼ 10 ^5.4 M _⊙ and to be radiating close to its Eddington limit ( L _bol / L _Edd ∼ 0.75 ...

UniverseDistinguishing 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 JournalWe 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.

Ionized Gas Components in Low Surface Brightness Galaxy AGC 111629
The Astronomical JournalWe present integral field spectroscopy of ionized gas components in AGC 111629, an edge-on low surface brightness galaxy with a stellar mass of 5.7 × 10 ^8 M _⊙ .

What Does the LMC Look Like? It Depends on [M/H] and Age
The Astrophysical JournalWe offer a new way to look at the LMC through stellar mono-abundance and mono-age mono-abundance maps. These maps are based on ≳500,000 member stars with estimates of [M/H] ( σ _[M/H] ~ 0.17) and age $({\sigma }_{{\rm{log}}\tau }\unicode{x0007E}0.15$ ),
