NIR jets from a clustered region of massive star formation: Morphology and composition in the IRAS 18264-1152 region
A. R. Costa Silva, R. Fedriani, J. C. Tan +6
Massive stars form deeply embedded in their parental clouds, making it challenging to directly observe these stars and their immediate environments. It is known that accretion and…
Astrochemical modelling of infrared dark clouds
Negar Entekhabi, Jonathan C. Tan, Giuliana Cosentino +8
Infrared dark clouds (IRDCs) are cold, dense regions of the interstellar medium (ISM) that are likely to represent the initial conditions for massive star formation. It is thus imp…
The Core Mass Function Across Galactic Environments. III. Massive Protoclusters
Theo J. O'Neill, Giuliana Cosentino, Jonathan C. Tan +2
The stellar initial mass function (IMF) is fundamental for many areas of astrophysics, but its origin remains poorly understood. It may be inherited from the core mass function (CM…
The complex organic molecular content in the L1498 starless core
Izaskun Jimenez-Serra, Anton I. Vasyunin, Silvia Spezzano +3
Observations carried out toward starless and pre-stellar cores have revealed that complex organic molecules are prevalent in these objects, but it is unclear what chemical processe…
ALMA-IRDC II. First high-angular resolution measurements of the 14N/15N ratio in a large sample of infrared-dark cloud cores
F. Fontani, A. T. Barnes, P. Caselli +6
The 14N/15N ratio in molecules exhibits a large variation in star-forming regions, especially when measured from N2H+ isotopologues. However, there are only a few studies performed…
ALMA-IRDC: Dense gas mass distribution from cloud to core scales
A. T. Barnes, J. D. Henshaw, F. Fontani +15
Infrared dark clouds (IRDCs) are potential hosts of the elusive early phases of high-mass star formation (HMSF). Here we conduct an in-depth analysis of the fragmentation propertie…
