Multiline observations of hydrogen, helium, and carbon radio-recombination lines toward Orion A: A detailed dynamical study and direct determination of physical conditions
C. H. M. Pabst, J. R. Goicoechea, S. Cuadrado +3
We present a study of hydrogen, helium, and carbon millimeter-wave radio-recombination lines (RRLs) toward ten representative positions throughout the Orion Nebula complex, using t…
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…
Dents in the Veil: Protostellar feedback in Orion
U. Kavak, J. Bally, J. R. Goicoechea +3
Interest in stellar feedback has recently increased because new studies suggest that radiative and mechanical feedback from young massive stars regulate the physical and chemical c…
Breaking Orion's Veil bubble with fossil outflows
U Kavak, J. R. Goicoechea, C. H. M. Pabst +3
The role of feedback in the self-regulation of star formation is a fundamental question in astrophysics. The Orion Nebula is the nearest site of ongoing and recent massive star for…
[CII] 158m emission from Orion A. II. Photodissociation region physics
C. H. M. Pabst, J. R. Goicoechea, A. Hacar +10
The [CII] 158m fine-structure line is the dominant cooling line of moderate-density photodissociation regions (PDRs) illuminated by moderately bright far-ultraviolet (FUV) radia…
Observation and calibration strategies for large-scale multi-beam velocity-resolved mapping of the [CII] emission in the Orion molecular cloud
R. Higgins, S. Kabanovic, C. Pabst +15
Context. The [CII] 158micron far-infrared fine-structure line is one of the dominant cooling lines of the star-forming interstellar medium (ISM). Hence [CII] emission originates in…
[CII] line emission from Orion A. I. A template for extragalactic studies?
C. H. M. Pabst, A. Hacar, J. R. Goicoechea +10
The [CII] fine-structure line is one of the dominant coolants of the neutral interstellar medium. It is hence one of the brightest far-infrared emission lines an…
SOFIA FEEDBACK survey: exploring the dynamics of the stellar wind driven shell of RCW 49
M. Tiwari, R. Karim, M. W. Pound +13
We unveil the stellar wind driven shell of the luminous massive star-forming region of RCW 49 using SOFIA FEEDBACK observations of the [CII] 158 m line. The complementary datase…
FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation
N. Schneider, R. Simon, C. Guevara +37
FEEDBACK is a SOFIA legacy program dedicated to study the interaction of massive stars with their environment. It performs a survey of 11 galactic high mass star forming regions in…
Expanding bubbles in Orion A: [CII] observations of M42, M43, and NGC 1977
C. H. M. Pabst, J. R. Goicoechea, D. Teyssier +7
The Orion Molecular Cloud is the nearest massive-star forming region. Massive stars have profound effects on their environment due to their strong radiation fields and stellar wind…
Molecular globules in the Veil bubble of Orion. IRAM 30m 12CO, 13CO, and C18O 2-1 expanded maps of Orion A
J. R. Goicoechea, C. H. M. Pabst, S. Kabanovic +13
Strong winds and ultraviolet (UV) radiation from O-type stars disrupt and ionize their molecular core birthplaces, sweeping up material into parsec-size shells. Owing to dissociati…
Carbon radio recombination lines from gigahertz to megahertz frequencies towards Orion A
P. Salas, J. B. R. Oonk, K. L. Emig +4
Context. The combined use of carbon radio recombination lines (CRRLs) and the 158 m-[CII] line is a powerful tool for the study of the energetics and physical conditions (e.g.,…
Disruption of the Orion Molecular Core 1 by the stellar wind of the massive star Ori C
C. Pabst, R. Higgins, J. R. Goicoechea +10
Massive stars inject mechanical and radiative energy into the surrounding environment, which stirs it up, heats the gas, produces cloud and intercloud phases in the interstellar me…
Berwald spacetimes and very special relativity
Andrea Fuster, Cornelia Pabst, Christian Pfeifer
In this work we study Berwald spacetimes and their vacuum dynamics, where the latter are based on a Finsler generalization of the Einstein's equations derived from an action on the…
