First detection of C2H+ in the interstellar medium
Arshia M. Jacob, Karl M. Menten, Sandra Brünken +10
Despite the detection of nearly 350 molecules in the interstellar medium, almost half of which are carbon chains, the pathways that build molecular complexity remain poorly underst…
CASCADE: Filamentary accretion flows in Cygnus X DR20
M. Sawczuck, H. Beuther, S. Suri +11
Aims. We investigate the role of filaments in high-mass star formation, whether gas flows from large to small scales along them, and what their properties might reveal about the re…
APEX survey of interstellar HCl: Cl/Cl isotopic ratios in dense cores and outflows
Lennart M. Böhm, Arshia M. Jacob, Friedrich Wyrowski +3
Despite being only the 19th most abundant element in the interstellar medium, chlorine's reactivity and volatility give rise to a unique interstellar chemistry, favouring the forma…
SOFIA FEEDBACK Survey: The Eagle Nebula in [C II] and Molecular Lines
Ramsey L. Karim, Marc W. Pound, Alexander G. G. M. Tielens +15
We characterize the physical conditions and energy budget of the M16 H II region using SOFIA FEEDBACK observations of the [C II] 158 m line. The O stars in the $\sim 10^{4}~{\r…
OGHReS: Star formation in the Outer Galaxy II (-)
J. S. Urquhart, C. Koenig, D. Colombo +19
The Outer Galaxy High-Resolution Survey (OGHReS) covers 100 square degrees () in the (2--1) transitions of three CO-isotopologues. We use the spectra…
SOFIA FIFI-LS spectroscopy of DR21 Main: energetics of the spatially-resolved outflow from a high-mass protostar
A. Karska, M. Figueira, A. Mirocha +12
Massive star formation is associated with energetic processes that may influence the physics and chemistry of parental molecular clouds and impact galaxy evolution. The high-mass p…
