How do I download actual academic papers from the portal?

For reasons of copyright, we do not post actual academic papers on the Technosignature Research Portal. We do endeavor to share, wherever possible, an external link to any academic paper if we can find a prepress copy. Unfortunately, not all research is available through prepress servers, in which case the link we share is often to a paywalled copy. If this is inconvenient, we agree. We believe that scientific research (particularly publicly funded research, and research which piggybacks on publicly funded organizations like NASA, or publicly funded equipment like the Hubble Space Telescope) should be open, not paywalled by for-profit companies at exorbitant subscription rates. Sadly, this is a common compliant across all of academia, not just within cosmology.
