The Vela Molecular Ridge is a nearby (~700 pc) giant molecular cloud in the southern sky hosting many active star formation sites. These are valuable targets for future observations with ALMA and Herschel. In particular, IRAS08448-4343 displays many signposts of star formation, such as different jets and a young cluster embedded within the associated molecular core. We have performed a detailed study of the region, covering a wide spectral range from the near IR to the mm-band, exploiting both imaging and spectroscopical ESO facilities in each spectral regime. A picture emerges of a dust structure which hosts a near IR cluster and multiple well collimated H2 jets; these originate from different sources lying in a compact region at the cluster centre. The peak of the 1.2mm map does not coincide with the IRAS peak, tracing a denser and colder region of dust emission with respect to that probed by IRAS. The mm peak is associable with the position of a red object, proposed as the driving source of the main jet in the field, which is extended along more than 0.3 pc. The driving source is resolved in at least six 2 μm peaks, being the reddest and coldest of them well aligned with the inner knots of the jet. The spectral energy distribution of this source well resembles that of a low mass, Class I protostar.
