VizieR Online Data Catalog: GMC's properties cat. in Cen A mol. disc (Miura+, 2021)

The Atacama Large Millimeter/submillimeter Array (ALMA) is providing an excellent view on what the molecular properties of truly elliptical galaxies (e.g. Boizelle et al. 2017ApJ...845..170B ; Temi et al. 2018ApJ...858...17T ; Vila-Vilaro et al. 2019ApJ...870...39V). Here, we present the GMC properties within the molecular disc of the closest giant elliptical galaxy, NGC 5128, which is the host of the radio-source Centaurus A. In this paper, we aim at providing a census of the GMCs as traced by CO(1-0) down to GMC masses of 105 M_ȯ and within the inner 4 kpc of an elliptical galaxy using high resolution (~20 pc), sensitivity (10 mJy/beam in 2 km s-1 channels), and dynamic range observations obtained with ALMA. The CO(1-0) line data were obtained with the 12 m, 7 m, and total Power (TP) arrays and therefore the final combined maps have information from small to large spatial scales.

Thanks to high angular resolution, we were able to resolve the molecular component into tens of parsec scale clouds. Thus, we identified GMCs with the cprops package (Rosolowsky & Leroy 2006PASP..118..590R) and derived cloud properties. A total of 689 GMCs were identified by the algorithm and their properties are listed in table1.dat.
