Seamless linkages (between data archives) for visualization and analysis (@AAS 2024), at New Orleans, LA, Thursday, January 11, 2024:

LIVE Astro logo on laptop covered with stickersAn early invited presentation of LIVE Environments. The focus was on the origins of LIVE Astro, and on how it can be used to connect "data, language, and pictures," in line with the mission layed out by Goodman et al. in "The Paper of the Future" in 2015.  Delivered in the context of a AAS-hosted discussion of strategy for astronomical data archives' strategy, worldwide.

The New Milky Way near the Sun (a discussion at the Harvard ITC) Thursday, September 14, 2023

Combinations of 3D dust maps of the ISM and 3D measurements of the motions of young stars have recently revealed two previously unseen phenomena: 1.) a gigantic undulation in the Local Arm of the Galaxy ("The Radcliffe Wave"); and 2.) a preponderance of SN-driven bubbles nearby, the largest of which (the "Local Bubble") is roughly centered on the current position of the Sun. Meanwhile, simulations of star-forming galaxies are becoming "nearly" good enough to search for simulated analogs to The Radcliffe Wave and the bubbly ISM around us. It's debatable whether any true analogs have been found, so let's debate and collaborate!

The NEW Milky Way (Munich Physics Colloquium), at LMU, Munich, Monday, June 12, 2023:

Thanks in large part to Gaia observations of the Milky Way and rapid advances in data science, it has very recently become possible to map out: 1) the three-dimensional internal structure and galactic arrangement of star-forming regions and 2) the positions and motions of young stars forming in those regions—also in 3D. These advances are painting a NEW picture of NEW (freshly-formed!) parts of the Milky Way.  The 3D, moving,  picture we can re-create from the data is giving hints as to the origins of oscillations in the Galaxy's arms (e.g. The Radcliffe Wave) as well as to the role of feedback (e.g. in the Local Bubble) from supernovae in driving the formation of dense gas, and ultimately stars. The talk will focus primarily on science, while also including demonstrations of how data science and visualization tools, including glue, WorldWide Telescope and OpenSpace, have enabled these discoveries.

Exploring High-Dimensional Data in Astronomy, Genomics, and beyond, using glue, at ViZTIG Seminar (Alan Turing Institute) online, with Jonathan Foster, Friday, March 10, 2023:

Through an online ViZTIG seminar (Alan Turing Institute), Alyssa Goodman with collaborator Jonathan Foster explains the origins of glue, paying homage to its ancestors DataDesk and Igor, and to cousins like Tableau. Specifically, they show how the high-dimensional nature of data in astronomy, genomics, medicine, and other areas essentially requires a glue-like approach to make the most of the information at-hand.
