12 resultsGalactic HII regions in LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Yunning Zhao, Wei Zhang, Lin Ma +10
The paper uses LAMOST medium‑resolution spectra to confirm 255 Galactic H II regions in the outer Milky Way and measures their electron temperature, density, and oxygen abundance t…
Exploring the Limits of Spectral Line Stacking in Spectral Line Data and Application Toward the Detection of Bulk C Enrichment of Aromatics in TMC-1
Miya Duffy, Ryan A. Loomis, Martin S. Holdren +9
The paper evaluates spectral line stacking and matched‑filter techniques to detect faint 13C‑substituted aromatic molecules in the cold cloud TMC‑1, demonstrating the method’s abil…
The evolution of galaxy dust scaling relations in the COLIBRE simulations
Aswin P. Vijayan, James W. Trayford, Joop Schaye +11
The paper uses the COLIBRE cosmological simulations to study how dust mass, composition, and grain sizes in galaxies evolve from the early Universe to the present, comparing predic…
Space as a spectroscopic laboratory: High-resolution spectroscopy of the [C II] hyperfine structure with SOFIA/upGREAT
S. Kabanovic, V. Ossenkopf-Okada, S. Schlemmer +13
The paper uses high‑resolution SOFIA/upGREAT observations of the 158 µm [13C II] line to directly measure its hyperfine splitting and determine the magnetic‑dipole hyperfine consta…
The COLIBRE-SKIRT pipeline: Calibration-free dust radiative transfer postprocessing for cosmological simulations
Andrea Gebek, Maarten Baes, Nick Andreadis +16
The paper introduces the COLIBRE‑SKIRT pipeline, a calibration‑free method that uses the SKIRT radiative transfer code to generate multi‑wavelength mock observations from large‑vol…
The World Cup in space: Finding ionised buckyballs in the ISM with CARMENES
J. MaÃz Apellániz
The paper reports the detection of ionised buckminsterfullerene (C₆₀⁺) in the interstellar medium by using multi‑epoch CARMENES spectra to shift diffuse interstellar bands away fro…
Pitch-Angle Scattering of Cosmic Rays: Confronting Theory with Observations
Huirong Yan, Siqi Zhao, Ming Zhang
The paper compares cosmic‑ray pitch‑angle diffusion inferred from Tibet ASγ anisotropy measurements in the local interstellar medium with theoretical models, finding that scatterin…
Investigating anomalous microwave emission near G107.2+5.20 in Ku-band with the Green Bank Telescope
Jordan E. Shroyer, Bradley R. Johnson, Dillon J. Bass +6
The authors use Green Bank Telescope Ku‑band observations to map the region around G107.2+5.20, constraining the low‑frequency side of the anomalous microwave emission spectrum and…
