Interstellar medium phases and abundances in the central parsec: A JWST MIRI/MRS view of the Galactic center
P. Vermot, A. Ciurlo, D. Rouan +8
We used newly obtained observations from the Mid-Infrared Instrument (MIRI) equipped with the Medium Resolution Spectrometer (MRS) aboard the James Webb Space Telescope (JWST) to e…
Bottlenecks to interstellar sulfur chemistry: Sulfur-bearing hydrides in UV-illuminated gas and grains
J. R. Goicoechea, A. Aguado, S. Cuadrado +8
Hydride molecules lie at the base of interstellar chemistry, but the synthesis of sulfuretted hydrides is poorly understood. Motivated by new observations of the Orion Bar PDR - 1'…
The ALMA view of UV irradiated cloud edges: unexpected structures and processes
Javier R. Goicoechea, S. Cuadrado, J. Pety +8
Far-UV photons (E<13.6 eV) from hot massive stars regulate, or at least influence, the heating, ionization, and chemistry of most of the neutral interstellar medium. Investigating…
Spatially resolved images of reactive ions in the Orion Bar
Javier R. Goicoechea, S. Cuadrado, J. Pety +6
We report high angular resolution (4.9" x 3.0") images of reactive ions SH+, HOC+, and SO+ toward the Orion Bar photodissociation region (PDR). We used ALMA-ACA to map several rota…
PDRs4All. X. ALMA and JWST detection of neutral carbon in the externally irradiated disk d203-506: Undepleted gas-phase carbon
Javier R. Goicoechea, J. Le Bourlot, J. H. Black +26
The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated i…
HCN emission from translucent gas and UV-illuminated cloud edges revealed by wide-field IRAM 30m maps of Orion B GMC: Revisiting its role as tracer of the dense gas reservoir for star formation
M. G. Santa-Maria, J. R. Goicoechea, J. Pety +28
We present 5 deg^2 (~250 pc^2) HCN, HNC, HCO+, and CO J=1-0 maps of the Orion B GMC, complemented with existing wide-field [CI] 492 GHz maps, as well as new pointed observations of…
