Massive Data Reduction

ALMA + IRAM-30m spectral cubes

As part of the technical work in this project, in our EMERGE Paper I (Hacar et al 2024) we developed a homogeneous and systematic data reduction framework allowing the massive data processing of ALMA observations using high-performance computers.

Continuum observations

As part of the Survey of Orion Disks with ALMA (SODA) project (van Terwisga, Hacar, van Dishoeck, Oonk, and Portegies Zwart, 2022), we investigate a total of 872 proto-planetary disks with ALMA in the Orion A cloud. Tailored for this project, EMERGE created a new scheme for the reduction of massive ALMA datasets using the SPIDER-SURF supercomputer. Contrary to previous linear methods, EMERGE creates a parallel data processing using the full capabilities of SPIDER-SURF, reducing the total reduction time by 2 orders of magnitude.
