APEX-LABOCA Flux Map of M83 Released

Published: 08 Oct 2020

A new data release is available that includes a flux map at 870 μm for the galaxy M83 (NGC 5236). It is obtained from the combination of the observations taken with the Large APEX Bolometer Camera (LABOCA) at the Atacama Pathfinder Experiment (APEX), under the ESO programme id 081.C-0827(A), PI A. Lundgren, between 2008-06-19 and 2008-06-30.

The total exposure time of the flux map is 10.5 hours, it has a signal to noise ratio of 47 in the galaxy central region, while the inner spiral arms are detected with a signal to noise ratio of more than 3. The atmospheric window of 870 μm, in which LABOCA operates, provides the opportunity to study the dust in the interstellar medium and the grain size distribution.

More information is available in the release documentation. The data can be accessed via the ESO Science Portal or programmatically.
