We present observations of the four 2 Pi 3/2 J = 3/2 ground-rotational state transitions of the hydroxyl molecule (OH) along 107 lines of sight both in and out of the Galactic plane: 92 sets of observations from the Arecibo telescope and 15 sets of o

The hydroxyl satellite-line ‘flip’ as a tracer of expanding H ii regions

Autor: Anita Petzler, Mark Wardle, Joanne Dawson

Publikováno v: Monthly Notices of the Royal Astronomical Society. 497:4066-4076

Observations of the four $^{2}\Pi_{3/2},~J = 3/2$~ground state transitions of the hydroxyl radical (OH) have emerged as an informative tracer of molecular gas in the Galactic ISM. We discuss an OH spectral feature known as the `flip', in which the sa

Amoeba: Automated Molecular Excitation Bayesian Line-fitting Algorithm

Autor: Mark Wardle, Anita Petzler, Joanne Dawson

Publikováno v: The Astrophysical Journal. 923:261

The hyperfine transitions of the ground-rotational state of the hydroxyl radical (OH) have emerged as a versatile tracer of the diffuse molecular interstellar medium. We present a novel automated Gaussian decomposition algorithm designed specifically
