Dataset/Dataset

Abstract: This collection provides millimetre spectroscopic and photometric imaging obtained with the CONCERTO instrument on APEX. The data cover the frequency range 130–310 GHz (0.97–2.3 mm) at a typical angular resolution of 27″ at 250 GHz and a spectral resolution of 6 GHz (sampled at 3 GHz). The spectroscopic datasets consist of calibrated maps combined into three-dimensional spectral cubes, from which continuum intensity, spectral slope, and line-integrated maps are derived for prominent molecular and atomic transitions (e.g. CO (2–1), H₂O 183 GHz). Complementary broadband photometric maps provide spatially resolved measurements of the millimetre continuum. These observations open new access to the spectral domain of dust emission, enabling simultaneous measurements of continuum and line emission across a wide range of environments. The data enable studies of spatial variations in the dust emissivity index, disentanglement of molecular and radio contributions, and investigations of the structure, dynamics, and energetics of the interstellar medium. The resulting products provide a valuable reference for characterising dust, gas, and feedback processes at millimetre wavelengths in Galactic and extragalactic sources.
Other: This is a dynamic dataset; it is growing as new data is added. The DOI refers to the newest available dataset.
