Oxygen Abundance Throughout the Dwarf Starburst Galaxy IC 10

The Astronomical Journal
Measurements of oxygen abundance throughout galaxies provide insight to the formation histories and ongoing processes. Here we present a study of the gas-phase oxygen abundance in the H ii regions and diffuse gas of the nearby starburst dwarf galaxy, IC ...

Unveiling Physical Conditions and Star Formation Processes in the G47 Filamentary Cloud

The Astrophysical Journal
We present a multiwavelength study of the filamentary cloud G47 ( d ∼ 4.44 kpc), which hosts the mid-infrared bubbles N98, B1, and B2. The SMGPS 1.3 GHz continuum map detects ionized emission toward all the bubbles, marking the first detection of ionized

Quantification of the Age Dependence of Mid-infrared Star Formation Rate Indicators

The Astrophysical Journal
We combine James Webb Space Telescope images of the nearby galaxy NGC 5194 in the hydrogen recombination line Pa α (1.8756 μ m) from the Cycle 1 program JWST-FEAST with 21 μ m dust continuum images from the Cycle 2 Treasury program JWGT to quantify the ...

H II regions in peculiar galaxies

The Astrophysical Journal, 1975
A survey of 32 galaxies, either classified as peculiar or having peculiar distributions of H ii regions, is presented in order to ascertain the range of the peculiarities and the degree to which they are similar. Ten different types are recognized, several of which are interrelated.

Masses, Star Formation Efficiencies, and Dynamical Evolution of 18,000 H ii Regions

The Astrophysical Journal Letters
We present measurements of the masses associated with ∼18,​​​​​000 H ii regions across 19 nearby star-forming galaxies by combining data from JWST, Hubble Space Telescope, MUSE, Atacama Large Millimeter/submillimeter Array, Very Large Array, and MeerKAT ...
