ALMA Developments

EMERGE leads and participates in different technical projects for ALMA (see below).

For further information, please contact us.

Archival research

In collaboration with the Dutch ARC-node Allegro, EMERGE is developing the new "ALminer: ALMA archive mining and visualization toolkit" (Ahmadi & Hacar 2021), a novel series of interactive tools to effectively query and analyze the ALMA Science Archive.

06/2021: ALminer is available in Github (EMERGE-StG Github)

Supercomputers & Massive Data Reduction

EMERGE is developing a new framework for massive data reduction in the ALMA era using supercomputers such as SURFsara/Spider (Amsterdam) (link).
Pilot project: This technique has been successfully applied on a the analysis of the first Survey of Orion disks with ALMA (SODA; van Terwisga, Hacar, & van Dishoeck, et al, 2022 accepted by A&A).

Data Combination

The recovery of extended emission is one of the most fundamental challenges for interferometric mapping. EMERGE is exploring multiple data combination techniques for improving the data combination process of ALMA data alone as well as with other single-dish telescopes (see more details in our Data Combination page).

The image consists of three panels that all show the same region in a molecular cloud, where the emission is in red, but with different spatial resolution. The first panel shows the region with ALMA 12m only data, the second panel shows the region with IRAM 30m data. Between those two panels is a plus sign. Between the second and the third panel is a equal sign. The third panel shows the combination of the two observations, and is labeled ALMA + IRAM30m
