Geminga is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Contemporary. It is the name of PSR B0633+17 in constellation Gem. NASA ADS lists 844 publications with “Geminga” in abstract. Name listed in Lortet & Spite (1986) IAU dictionary of names.
Etymology and History
Geminga is an artificially invented term for the gamma-ray and X-ray pulsar discovered and named by Giovanni Bignani+ 1983, see footnote below. Bignami (1944-2017) was an Italian physicist, later chairman of Italian Space Agency (2007-2008)
The authors explain the pun: "This source is in the constellation of Gemini and it is a gamma-ray source. Pronounced with both G's as in "get", the word means "does not exist" or "it's not there" in Milanese dialect.
