PP7 chapter: Initial conditions for Star Formation: A physical description of the filamentary ISM
The Protostars and Planets Conference takes place every five to ten years. Its aim is to summarize the state-of-the-art and progress achieved in the research fields of star and planet formation. The next Protostars and Planets VII (PP7) will take place in Kyoto in 2023. Our team has participated in the new PP7 chapter (Hacar, Clark, Heitsch, Kainulainen, Panopoulou, Seifried, & Smith 2022) investigating the "Initial Conditions for Star Formation: A Physical description of the filamentary ISM". Condensing the progress made in this field within the last decade, we have explore the physical conditions of different filamentary structures in the ISM at all scales. Using a large meta-data study this paper reveals new properties and scaling relations of the ISM filaments. Also, it discussed some of the main challenges and potential avenues for the future.

Observing 873 proto-planetary disks with SODA: massive ALMA data processing using Supercomputers
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. As part of its contribution, EMERGE is developing a new scheme for the reduction of massive ALMA datasets using supercomputers such as SURFsara. Contrary to previous linear methods, EMERGE creates a parallel data processing using the full capabilities of SURFsara, reducing the total reduction time by 2 orders of magnitude. Visit the SODA section to obtain all data products (FITS and PNG images) of this project.
