About ACROSS

The very nature of multimessenger and time domain astronomy calls for the coordination of resources and expertise from diverse domains of astrophysics, cosmology, and physics to correlate and interpret data from multiple messengers to enable further groundbreaking discoveries. Progress in this field depends on many stakeholders working together efficiently - not only scientists from the astronomy and physics, ground- and space-based communities, but also engineers, software developers, data and communication scientists, and more. This paradigm shift in astronomical research, thus, depends as much on technological advancements and scientific acumen as on the collaboration, communication, and infrastructure frameworks that are in place to enable such multifaceted exploration of the universe. The vision at the core of Astrophysics Cross-Observatory Science Support (ACROSS) center is the recognition that progress in MMA/TDA science can only be achieved if all stakeholders Communicate (often and regularly), Coordinate (plan and execute together), and Collaborate (share ideas and tools) - the three Cs. The challenges to MMA/TDA of the 21st century, with the improved sensitivities of ground- and space-based facilities, require nothing less.
