THE REDSHIFT OF EXTRAGALACTIC NEBULAE
(Die Rotverschiebung von extragalaktischen Nebeln)
Fritz Zwicky
(Translated by H. Andernach heavily editing a raw translation from
https://tradukka.com/translate)
Abstract: This gives a description of the most essential
characteristics of extragalactic nebulae, as well as of the methods used
to investigate these. In particular, the so-called redshift of
extragalactic nebulae is discussed in detail. Various theories which
have been proposed to explain this important phenomenon, are briefly
discussed. Finally, it will be indicated to what extent the redshift
promises to become of importance for the study of cosmic rays.

Special terms were interpreted as follows:
- Nebel = nebula (not galaxy, to preserve the original flavor of the text)
- Fluchtgeschwindigkeit = recession velocity (not escape velocity, as
there is no escape here...)
- Perioden-Helligkeits-Beziehung = Period-Brightness Relationship
(not period-luminosity, to preserve the original word "Helligkeit")
- penetrating radiation = cosmic rays
