Interstellar communication. VI. Searching X-ray spectra for narrowband communication
Michael Hippke, Duncan H. Forgan
We have previously argued that targeted interstellar communication has a physical optimum at narrowband X-ray wavelengths nm, limited by the surface roughness of focus…
Interstellar communication. V. Introduction to photon information efficiency (in bits per photon)
Michael Hippke
How many bits of information can a single photon carry? Intuition says "one", but this is incorrect. With an alphabet based on the photon's time of arrival, energy, and polarizatio…
Interstellar communication. VII. Benchmarking inscribed matter probes
Michael Hippke, Paul Leyland, John G. Learned
We have explored the optimal frequency of interstellar photon communications and benchmarked other particles as information carriers in previous papers of this series. We now compa…
Interstellar communication. III. Optimal frequency to maximize data rate
Michael Hippke, Duncan H. Forgan
The optimal frequency for interstellar communication, using "Earth 2017" technology, was derived in papers I and II of this series (arXiv:1706.03795, arXiv:1706.05570). The framewo…
Interstellar communication. IV. Benchmarking information carriers
Michael Hippke
The search for extraterrestrial communication has mainly focused on microwave photons since the 1950s. We compare other high speed information carriers to photons, such as electron…
Photogravimagnetic assists of light sails: a mixed blessing for Breakthrough Starshot?
Duncan H. Forgan, René Heller, Michael Hippke
Upon entering a star system, light sails are subject to both gravitational forces and radiation pressure, and can use both in concert to modify their trajectory. Moreover, stars po…
