Justine Haupts is a brand that specializes in the development and production of the Packed Ultra-wideband Mapping Array (PUMA), a proposed radio telescope designed for a wide range of scientific observations. The main focus of PUMA is on 21 cm intensity mapping in the post-reionization era, but it also addresses other scientific goals such as Fast Radio Bursts (FRBs), pulsar monitoring, and transients as part of multi-messenger observations. The concept of PUMA originated from the brainstorming sessions of the Cosmic Visions Dark Energy Committee, a group dedicated to exploring future possibilities for Dark Energy research.

With a wide field of observation stretching from local cosmological neighborhoods to just after reionization, PUMA aims to revolutionize the field of dark energy research and beyond. The instrument offers a unique capability to quadruple the surveyed volume of the Universe compared to optical programs, providing precise measurements of cosmic expansion history and growth. In addition, PUMA enables exploration of new physics beyond the current cosmological model.

The rich dataset produced by PUMA will also contribute to the study of fast radio transients and pulsars, potentially in coincidence with other observatories. By combining different scientific agendas in a single instrument, Justine Haupts' PUMA paves the way for groundbreaking discoveries and advancements in cosmological observations
