Structure and Fragmentation of a high line-mass filament: Nessie
Michael Mattern, Jouni Kainulainen, Miaomiao Zhang +1
An increasing number of hundred-parsec scale, high line-mass filaments have been detected in the Galaxy. Their evolutionary path, including fragmentation towards star formation, is…
Characterizing the interplay between Galactic star formation and ionization feedback with PRIMA
Annie Zavagno, Delphine Russeil, Paolo Suin +13
Recent results from the James Webb Space Telescope show that nearby spiral galaxies are dominated by the presence of H I and H II bubbles that strongly shape their surrounding medi…
Star-forming content of the giant molecular filaments in the Milky Way
Miaomiao Zhang, Jouni Kainulainen, Michael Mattern +2
Observations have discovered numerous giant molecular filaments (GMFs) in the Milky Way. However, their role in the Galactic star formation and Galaxy-scale evolution of dense gas…
Structure and Fragmentation Scale of a Massive Star-Forming Filament in NGC6334: High-Resolution Mid-Infrared Absorption Imaging with JWST
Philippe André, Michael Mattern, Doris Arzoumanian +4
Dense filaments are believed to be representative of the initial conditions of star formation in molecular clouds. We have used the MIRI instrument on JWST to image the massive fil…
Mapping CO Ice in a Star-Forming Filament in the 3 kpc Arm with JWST
Savannah Gramze, Adam Ginsburg, Nazar Budaiev +14
CO gas emission is a fundamental tool for measuring column density, but in cold, dark clouds, much of the CO is locked away in ice. We present JWST results from observations of a s…
ArTéMiS imaging of the filamentary infrared dark clouds G1.75-0.08 and G11.36+0.80: Dust-based physical properties of the clouds and their clumps
Oskari Miettinen, Michael Mattern, Philippe André
We imaged the infrared dark clouds (IRDCs) G1.75-0.08 and G11.36+0.80 at 350 m and 450 m using the ArTéMiS bolometer. These data were used in conjunction with our previous…
