Shared-optical-path VLBI frequency phase transfer from 86 to 258 GHz on an 8600 km baseline: Demonstrated with the APEX and IRAM 30 m telescopes
G. -Y. Zhao, A. L. Roy, J. F. Wagner +24
The receiver N3AR operating at a frequency range between 67 and 116 GHz has been commissioned at the APEX telescope in October 2024. This adds a new low-frequency band for APEX, wi…
Validation of millimetre and submillimetre atmospheric collision induced absorption at Chajnantor
J. R. Pardo, C. De Breuck, D. Muders +9
Due to the importance of a reference atmospheric radiative transfer model for both planning and calibrating ground-based observations at millimetre and submillimetre wavelengths, w…
The [OI] fine structure line profiles in Mon R2 and M17 SW: the puzzling nature of cold foreground material identified by [12CII] self-absorption
C. Guevara, J. Stutzki V. Ossenkopf-Okada, U. Graf +8
Context. Recent studies of the optical depth comparing [12CII] and [13CII] line profiles in Galactic star-forming regions revealed strong self-absorption in [12CII] by low excitati…
Infrared view of the multiphase ISM in NGC 253 II. Modelling the ionised and neutral atomic gas
André Beck, Vianney Lebouteiller, Suzanne C. Madden +9
Context. Multi-wavelength studies of galaxies and galactic nuclei allow us to build a relatively more complete picture of the interstellar medium (ISM), especially in the dusty reg…
Infrared view of the multiphase ISM in NGC 253 I. Observations and fundamental parameters of the ionised gas
André Beck, Vianney Lebouteiller, Suzanne Madden +7
Context. Massive star-formation leads to enrichment with heavy elements of the interstellar medium. On the other hand, the abundance of heavy elements is a key parameter to study t…
APEX Control System (APECS): Recent improvements and plans
Dirk Muders, Carsten König, Reinhold Schaaf +2
We report on recent improvements of the Atacama Pathfinder Experiment Control System (APECS) to cope with the ever increasing data rates and volumes. Also the very wide bandwidths…
