Abstract This English translation of the paper by F. Zwicky, “Die Rotverschiebung von extragalaktischen Nebeln”, Helv. Phys. Acta 6, 110–127 (1933), in which he concluded from the results of observations that the amount of non-luminous matter in the Universe must be greater than that of luminous matter—thus becoming an early precursor of the dark matter idea, has been selected for publication in the Golden Oldies series of General Relativity and Gravitation. The paper is accompanied by an… 

Expanding Earth and Static Universe: Two Papers of 1935

The German-born astronomer Jacob K. E. Halm (1866-1944) wrote in 1935 two papers on quite different subjects, one an astrophysically based argument for the expanding Earth and the other a no less

Possible existence of dark matter admixed pulsar

In our previous study (Molla in Eur Phys J Plus 135:362, 2020), we have discussed the possible existence of the dark matter admixed pulsars, based on Singular Isothermal Sphere density profile,

How the Nonbaryonic Dark Matter Theory Grew

The evidence is that the mass of the universe is dominated by an exotic nonbaryonic form of matter largely draped around the galaxies. It approximates an initially low pressure gas of particles that

Emergence of a dark force in corpuscular gravity

We investigate the emergent laws of gravity when dark energy and the de Sitter space-time are modeled as a critical Bose-Einstein condensate of a large number of soft gravitons NG. We argue that this


The recognition that the Universe is in a state of expansion is a milestone in modern astronomy and cosmology. The discovery dates from the early 1930s but was not unanimously accepted by either

Extragalactic Searches for Dark Matter Annihilation

We are at the dawn of a data-driven era in astrophysics and cosmology. A large number of ongoing and forthcoming experiments combined with an increasingly open approach to data availability offer

Observations of General Relativity at strong and weak limits

Einstein's General Relativity theory has been tested in many ways during the last hundred years as reviewed in this chapter. Two tests are discussed in detail in this article: the concept of a zero

Dark Matter Study of NGC 5055

This paper is about rediscovering dark matter (DM) in galaxies before the year 1970. It is an Italy-Malaysia Astroproject (SISSA-Radio Cosmology Research group), introducing to the field of DM.

Solar System Tests of Some Models of Modified Gravity Proposed to Explain Galactic Rotation Curves without Dark Matter

We consider the recently estimated corrections Δω¯˙ to the standard Newtonian/Einsteinian secular precessions of the longitudes of perihelia ω¯ of several planets of the Solar System in order to

A WDM model for the evolution of galactic halos

It is a well-known fact that the gravitational effect of dark matter in galaxies is only noticeable when the orbital accelerations drop below a0 2 × 10−8 cm s−1 (Milgrom's Law). This peculiarity of
