The following October, Avi Loeb, the chair of Harvard’s astronomy department, co-wrote a paper (with a Harvard postdoctoral fellow, Shmuel Bialy) that examined ‘Oumuamua’s “peculiar acceleration” and suggested that the object “may be a fully operational probe sent intentionally to Earth’s vicinity by an alien civilization.” The referenced paper is here: Could Solar Radiation Pressure Explain 'Oumuamua's Peculiar Acceleration? https://arxiv.org/abs/1810.11490 https://arxiv.org/abs/1810.11490
