"In the development of major technical collaborations, it is rare indeed for scientists, philosophers, historians, ethnographers, art historians, and sociologists to have the chance to think together about scientific knowledge as it unfolds. Here we have that possibility, not after the fact, but now, in the course of building instruments, observations, theories, and interpretations of black holes. We are shaping the start of this joint venture; its future to be built and written."
- Peter Galison, coordinator of the HPC working group
We have published a summary of the HPC white paper in The Conversation.
News
The ngEHT's Key Science Goals paper has been published in the journal Galaxies. This is the first time that the KSG of an (astro)physics collaboration explicitly includes goals related to the humanities and social sciences (§2.8).
The HPC White Paper has been published in Galaxies. The paper delineates the activities and future goals of the HPC Working Group. For various highlights, see The Conversation.

Focus Groups
Foundations
The Foundations focus group complements the Fundamental Physics working group, providing a different, critical lens for thinking about what the ngEHT observations can tell us about fundamental physics. It does so by facilitating ongoing interdisciplinary discussions of foundational issues, primarily through the weekly BHI Foundations Seminar.
