Backscattering and Line Broadening in Orion
The Astronomical Journal, 2022 Examination of emission lines in high-velocity-resolution optical spectra of the Orion Nebula confirms that the velocity component on the red wing of the main ionization front emission line is due to backscattering in the Photon Dominated Region.

The polarization of millimeter-wave emission lines in dense interstellar clouds
The Astrophysical Journal, 1983 Measurements of linear polarization are reported for thermally excited CO, /sup 13/CO, HCN, and CS in 14 dense clouds which encompass a broad range of physical conditions, gas dynamics, and possible magnetic field structure. Observing techniques are described which are sensitive to polarizations as small as 0.5%, and upper limits this small were ...

Reionization Era Bright Emission Line Survey: Selection and Characterization of Luminous Interstellar Medium Reservoirs in the z > 6.5 Universe [PDF]
The Astrophysical Journal, 2022 Abstract The Reionization Era Bright Emission Line Survey (REBELS) is a cycle-7 ALMA Large Program (LP) that is identifying and performing a first characterization of many of the most luminous star-forming galaxies known in the z > 6.5 universe.

The GBT Diffuse Ionized Gas Survey (GDIGS): Discrete Sources
The Astrophysical Journal, 2023 The Green Bank Telescope Diffuse Ionized Gas Survey (GDIGS) traces ionized gas in the Galactic midplane by observing radio recombination line (RRL) emission from 4 to 8 GHz. The nominal survey zone is 32.°3 > ℓ > −5°, ∣ b ∣ < 0.°5. Here, we analyze GDIGS

The Evolution of Emission Lines in HII Galaxies as a Probe of Interaction between Stellar and Interstellar Component [PDF]
Astrophysics and Space Science, 2002 HII galaxies are powered by clusters of hot massive stars ionizing their environment. By considering HII galaxies in different evolutionary stages with respect to the most recent star formation event, one can get insight into their evolution and interaction with the interstellar medium.

Estimating the Oblateness of Dark Matter Halos Using Neutral Hydrogen Velocity Dispersion
The Astrophysical Journal Letters, 2023 We derive the oblateness parameter q of the dark matter halo of a sample of gas-rich, face-on disk galaxies. We have assumed that the halos are triaxial in shape but their axes in the disk plane ( a and b ) are equal, so that q = c / a measures the halo ...
