We used the Large APEX Bolometer Camera LABOCA at the
APEX telescope to map
a 1.25 x 1.25 square-degree (50 x 50 pc^2) region at 870 micrometer with 18 arcsec angular
resolution (=0.2 pc at the distance of the Carina Nebula) and an rms noise level of about 20 mJy/beam.
Our analysis suggests a total gas + dust mass of about 200 000 Msun in the investigated area;
most of this material is in the form of molecular clouds, but a widely distributed component
of (partly) atomic gas, containing up to 50% of the total mass, may also be present.
Currently, only some 10% of the gas is in sufficiently dense clouds to be immediately
available for future star formation, but this fraction may increase with time owing
to the ongoing compression of the strongly irradiated clouds and the expected shockwaves
of the imminent supernova explosions.
These observations are part of our Carina Multiwavelength Project.
The main scientific results from this LABOCA observation are published
in:
A deep wide-field sub-mm survey of the Carina Nebula complex,
Th. Preibisch, F. Schuller, H. Ohlendorf, S. Pekruhl, K.M. Menten, H. Zinnecker,
Astronomy & Astrophysics, 525, A92 (2011) (preprint).
Further work is in progress.
In the image below the LABOCA data are shown in orange tones, combined with a visible light image from the Curtis Schmidt telescope at the Cerro Tololo Interamerican Observatory. This image was produced from our LABOCA data by ESO and published in the Photo Release 1145 .
New results will continuously be added as they become available.
