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

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 ...

New observations and models of circumstellar CO line emission of AGB stars in the Herschel SUCCESS programme [PDF]
, 2015 CONTEXT: Asymptotic giant branch (AGB) stars are in one of the latest evolutionary stages of low to intermediate-mass stars. Their vigorous mass loss has a significant effect on the stellar evolution, and is a significant source of heavy elements and ...
