JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
The Mid-Infrared Instrument for the James Webb Space Telescope, VI: The Medium Resolution Spectrometer
Martyn Wells, J. -W. Pel, Alistair Glasse +35
We describe the design and performance of the Medium Resolution Spectrometer (MRS) for the JWST-MIRI instrument. The MRS incorporates four coaxial spectral channels in a compact op…
Towards A Removal of Temperature Dependencies from Abundance Determinations
Kevin V. Croxall, J. D. Smith, B. R. Brandl +16
The metal content of a galaxy is a key property for distinguishing between viable galaxy evolutionary scenarios, and it strongly influences many of the physical processes in the in…
The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies
K. M. Sandstrom, A. K. Leroy, F. Walter +42
We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…
A Study of Heating and Cooling of the ISM in NGC 1097 with Herschel-PACS and Spitzer-IRS
P. Beirao, L. Armus, G. Helou +38
NGC 1097 is a nearby Seyfert 1 galaxy with a bright circumnuclear starburst ring, a strong large-scale bar and an active nucleus. We present a detailed study of the spatial variati…
Physical Conditions in the Ionized Gas of 30 Doradus
R. Indebetouw, G. E. de Messières, S. Madden +13
We present a mid-infrared spectroscopic data cube of the central part of 30 Doradus, observed with Spitzer's IRS and MIPS/SED mode. Aromatic dust emission features and emission lin…
