Electron temperature and emission measure of HII regions in the central molecular zone (CMZ) from H40 αrecombination line and continuum emissions by ALMA CMZ Exploration Survey - ACES -
Yoshiaki Sofue, Steven N. Longmore, Daniel Walker +40
Star formation activity in the Central Molecular Zone (CMZ) directly manifests itself as radio continuum free-free emission (Bremsstrahlung) and radio recombination line emission f…
An 18 - 25 GHz spectroscopic survey of southern hemisphere dense cores
Dariusz C. Lis, Karen Willacy, Liton Majumdar +3
We extended the radio K-band spectroscopic survey for organics in southern hemisphere dense cores by observing seven sources using NASA's Deep Space Network 70-m antenna in Canberr…
Expanding the Ice Inventory of NGC 1333 IRAS 2A with INDRA using JWST Observations: Tracing Organic Refractories and Beyond
Prathap Rayalacheruvu, Liton Majumdar, W. R. M. Rocha +7
In the era of JWST, with its unprecedented sensitivity and spectral resolution, infrared spectral surveys have revealed a rich inventory of ices, including complex organic molecule…
Modelling methanol and hydride formation in the JWST Ice Age era
Izaskun Jiménez-Serra, Andrés MegÃas, Joseph Salaris +19
(Abridged) JWST observations have measured the ice composition toward two highly-extinguished field stars in the Chamaeleon I cloud. The observed extinction excess on the long-wave…
Spatial and Chemical Complexity in the W75N Star-Forming Region
Morgan M. Giese, Will E. Thompson, Dariusz C. Lis +1
We present the analysis of NOEMA interferometric observations of the high-mass star-forming region W75N(B) with a focus on molecular composition and distribution of prebiotic molec…
