THE MAGNETIC FIELD OF THE IRREGULAR GALAXY NGC 4214 [PDF]
We examine the magnetic field in NGC 4214, a nearby irregular galaxy, using multi-wavelength radio continuum polarization data from the Very Large Array.

DEEP RADIO CONTINUUM IMAGING OF THE DWARF IRREGULAR GALAXY IC 10: TRACING STAR FORMATION AND MAGNETIC FIELDS [PDF]
We exploit the vastly increased sensitivity of the Expanded Very Large Array to study the radio continuum and polarization properties of the post-starburst, dwarf irregular galaxy IC 10 at 6 cm, at a linear resolution of ∼50 pc.

Automatic Detection of Galaxy Type From Datasets of Galaxies Image Based on Image Retrieval Approach
This paper presents a new approach for the automatic detection of galaxy morphology from datasets based on an image-retrieval approach. Currently, there are several classification methods proposed to detect galaxy types within an image.

Emission spectrum of ionized gas in the irregular galaxy Holmberg II [PDF]
We study the ionized gas spectrum of star forming regions in the Holmberg II galaxy using the optical long-slit spectroscopic observations made at the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS). We

CEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3–9 with JWST
We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3–9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z

Diffuse Ionized Gas in the Dwarf Irregular Galaxy DDO 53
The spectral characteristics throughout the dwarf irregular galaxy DDO 53 are studied. The results are very similar to those for other irregular galaxies: high excitation and low values of the [SII]/Halpha ratio.

THE M81 GROUP DWARF IRREGULAR GALAXY DDO 165. I. HIGH-VELOCITY NEUTRAL GAS IN A POST-STARBURST SYSTEM [PDF]
We present new multi-configuration Very Large Array H i spectral line observations of the M81 group dwarf irregular post-starburst galaxy DDO 165. The H i morphology is complex, with multiple column density peaks surrounding a large region of very low H ...

What Does the Milky Way Look Like?
In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us with an opportunity to solve this issue.

THE ROLE OF THE MAGNETIC FIELD IN THE INTERSTELLAR MEDIUM OF THE POST-STARBURST DWARF IRREGULAR GALAXY NGC 1569 [PDF]
NGC 1569 is a nearby dwarf irregular galaxy which underwent an intense burst of star formation 10–40 Myr ago. We present observations that reach surface brightnesses 2–80 times fainter than previous radio continuum observations and the first radio ...
