"Without the IIC's collaborative infrastructure, multidisciplinary resources, and other support, this research would not have happened," Halle said. Halle praised the IIC as an important forum within which researchers with different fields of expertise can work together. "You can take all the data, selectively filter it, and look at it in a different way." "You're learning about your data through visualization and interaction," said Halle. Michael Halle, senior scientist at the IIC and instructor in radiology at Harvard Medical School and Brigham and Women's Hospital, said this research shows that visualization technology is a critical part of the analysis and discovery process and not just a way to display data once it has been gathered, analyzed, and understood. "There's no way of noticing this without being able to see this in 3-D," Goodman said. Previous technology, Goodman said, doesn't allow for careful consideration of what she described as "hierarchical" structure - essentially regions within regions - and would have obscured specific details in the molecular cloud, such as nested areas of varying density and a physical break from one area to another.
Goodman and colleagues used the IIC technology to examine reams of astronomical data collected on a structure known as a giant molecular cloud.
The work was led by Astronomy Professor Alyssa Goodman of Harvard's Faculty of Arts and Sciences, the Harvard-Smithsonian Center for Astrophysics, and the Initiative in Innovative Computing (IIC), of which she was the founding director.
