A Framework for Incorporating Binding Energy Distribution in Gas-ice Astrochemical Models

The Astrophysical Journal
One of the most serious limitations of current astrochemical models with the rate equation (RE) approach is that only a single type of binding site is considered in grain surface chemistry, although laboratory and quantum chemical studies have found that

The Lyα Sky as Observed by New Horizons at 57 au

The Astronomical Journal
During 2023 September the Alice ultraviolet spectrograph on the New Horizons (NH) spacecraft was used to map diffuse Lyα emission over most of the sky, at a range of ∼56.9 au from the Sun.

Magnetic Fields in Giant Filaments Probed by the Velocity Gradient Technique: Regular Magnetic Field Interrupted by Magnetization Gaps

The Astrophysical Journal
We study the magnetic field structures in six giant filaments associated with the spiral arms of the Milky Way by applying the velocity gradient technique (VGT) to the ^13 CO spectroscopic data from the GRS, FUGIN, and SEDIGSM surveys.

Interstellar grain chemistry and organic molecules [PDF]

The detection of prominant infrared absorption bands at 3250, 2170, 2138, 1670 and 1470 cm(-1) (3.08, 4.61, 4.677, 5.99 and 6.80 micron m) associated with molecular clouds show that mixed molecular (icy) grain mantles are an important component of the ...

Evidence for Spatially Distinct Galactic Dust Populations

The Astrophysical Journal
We present an implementation of a Bayesian mixture model using Hamiltonian Monte Carlo techniques to search for the spatial separation of Galactic dust populations. Utilizing intensity measurements from the Planck High Frequency Instrument, we apply this
