We use polarization data from SOFIA HAWC+ to investigate the interplay between magnetic fields and stellar feedback in altering gas dynamics within the high-mass star-forming regio…
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…
Absorption and Self-Absorption of [C II] and [O I] Far Infrared Lines Towards a Bright Bubble in the Nessie Infrared Dark Cloud
J. M. Jackson, J. S. Whitaker, E. T. Chambers +15
Using the upGREAT instrument on SOFIA, we have imaged [C II] 157.74 and [O I] 63.18 micron line emission from a bright photodissociation region (PDR) associated with an ionized ``b…
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…
