Description of turbulent dynamics in the interstellar medium: Multifractal microcanonical analysis: II. Sparse filtering of Herschel observation maps and visualization of filamentary structures at different length scales
A. Rashidi, H. Yahia, S. Bontemps +15
We present significant improvements to our previous work on noise reduction in {\sl Herschel} observation maps by defining sparse filtering tools capable of handling, in a unified…
First detection of the [CII] 158 micron line in the intermediate-velocity cloud Draco
N. Schneider, V. Ossenkopf-Okada, E. Keilmann +7
High-latitude intermediate-velocity clouds (IVCs) are part of the Milky Way's HI halo and originate from either a galactic fountain process or extragalactic gas infall. They are pa…
The SOFIA FEEDBACK Legacy Survey: Rapid molecular cloud dispersal in RCW 79
L. Bonne, S. Kabanovic, N. Schneider +12
It has long been discussed whether stellar feedback in the form of winds and/or radiation can shred the nascent molecular cloud, thereby controlling the star formation rate. Howeve…
Identifying physical structures in our Galaxy with Gaussian Mixture Models: An unsupervised machine learning technique
M. Tiwari, R. Kievit, S. Kabanovic +14
We explore the potential of the Gaussian Mixture Model (GMM), an unsupervised machine learning method, to identify coherent physical structures in the ISM. The implementation we pr…
Formation of the Musca filament: Evidence for asymmetries in the accretion flow due to a cloud-cloud collision
L. Bonne, S. Bontemps, N. Schneider +11
Context. Dense molecular filaments are ubiquituous in the interstellar medium, yet their internal physical conditions and formation mechanism remain debated. Aims. We study the kin…
Strong CH+ J=1-0 emission and absorption in DR21
E. Falgarone, V. Ossenkopf, M. Gerin +30
We report the first detection of the ground-state rotational transition of the methylidyne cation CH+ towards the massive star-forming region DR21 with the HIFI instrument onboard…
Detection of interstellar oxidaniumyl: abundant H2O+ towards the star-forming regions DR21, Sgr B2, and NGC6334
V. Ossenkopf, H. S. P. Müller, D. C. Lis +99
We identify a prominent absorption feature at 1115 GHz, detected in first HIFI spectra towards high-mass star-forming regions, and interpret its astrophysical origin. The character…
HIFI observations of warm gas in DR21: Shock versus radiative heating
V. Ossenkopf, M. Röllig, R. Simon +35
The molecular gas in the DR21 massive star formation region is known to be affected by the strong UV field from the central star cluster and by a fast outflow creating a bright sho…
