H2 emission in the Orion Bar, NGC7023 and the Horsehead Nebula observed with the James Webb Space Telescope
M. Zannese, A. Sidhu, A. Guerras +25
Molecular hydrogen (H2), the most abundant molecule in the interstellar medium, is a handy tool to study Photodissociation Regions. The JWST, with its high spatial resolution, sens…
Unveiling the formation of the massive DR21 ridge
L. Bonne, S. Bontemps, N. Schneider +10
We present new CO(1-0), CO(1-0), HCO(1-0) and HCO(1-0) maps from the IRAM 30m telescope, and a spectrally-resolved [CII] 158 m map observed with…
Self-absorption in [CII], CO, and HI in RCW120. Building up a geometrical and physical model of the region
S. Kabanovic, N. Schneider, V. Ossenkopf-Okada +19
Revealing the 3D dynamics of HII regions and their associated molecular clouds is important for understanding the longstanding problem as to how stellar feedback affects the densit…
[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…
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…
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 and hydrogen radio recombination lines from the cold clouds towards Cassiopeia A
J. B. R. Oonk, R. J. van Weeren, P. Salas +5
We use the Low Frequency Array to perform a systematic high spectral resolution investigation of the low-frequency 33-78 MHz spectrum along the line of sight to Cassiopeia A. We co…
Low Frequency Carbon Radio Recombination Lines II: The Diffuse Interstellar Medium
F. Salgado, L. K. Morabito, J. B. R. Oonk +4
In the second paper of the series, we have modeled low frequency carbon radio recombination lines (CRRL) from the interstellar medium. Anticipating the LOw Frequency ARray (LOFAR)…
Low Frequency Carbon Radio Recombination Lines I: Calculations of Departure Coefficients
F. Salgado, L. K. Morabito, J. B. R. Oonk +4
In the first paper of this series, we study the level population problem of recombining carbon ions. We focus our study on high quantum numbers anticipating observations of Carbon…
The Orion HII Region and the Orion Bar in the Mid-Infrared
F. Salgado, O. Berné, J. D. Adams +2
We present mid-infrared photometry of the Orion Bar obtained with FORCAST aboard SOFIA at 6.4, 6.6, 7.7, 19.7, 31.5 and 37.1 \um. By complementing this observations with archival F…
On the nature of the enigmatic object IRAS 19312+1950: A rare phase of massive star formation?
M. A. Cordiner, A. C. A. Boogert, S. B. Charnley +7
IRAS 19312+1950 is a peculiar object that has eluded firm characterization since its discovery, with combined maser properties similar to an evolved star and a young stellar object…
The Physics of the Cold Neutral Medium: Low-frequency Carbon Radio Recombination Lines with the Square Kilometre Array
J. B. R. Oonk, L. K. Morabito, F. Salgado +4
The Square Kilometre Array (SKA) will transform our understanding of the role of the cold, atomic gas in galaxy evolution. The interstellar medium (ISM) is the repository of stella…
Discovery of Carbon Radio Recombination Lines in M82
Leah K. Morabito, J. B. R. Oonk, Francisco Salgado +30
Carbon radio recombination lines (RRLs) at low frequencies (<=500 MHz) trace the cold, diffuse phase of the interstellar medium, which is otherwise difficult to observe. We present…
