On the detection of a cosmic dawn signal in the radio background

Nature Astronomy, 2021
The astrophysics of the cosmic dawn, when star formation commenced in the first collapsed objects, is predicted to be revealed by spectral and spatial signatures in the cosmic radio background at long wavelengths.

Cosmic lacunarity

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1997
The present distribution of galaxies in space is a remnant of their formation and interaction. On a large enough scale, we may represent the galaxies as a set of points and quantify the structures in this set by its generalized dimensions [Beck and Schlögl, Thermodynamics of Chaotic Systems (Cambridge University Press, Cambridge, 1986); Paladin and ...

Cosmic Rays? Cosmic Particles

2021
Cosmic rays are not rays. They are high energy particles arriving from outside the atmosphere, produced by the Sun and a number of different types of high energy astronomical sources. I first explain how, in the early twentieth century Victor Hess in a high altititude balloon showed that they do not have a terrrestrial origin, and how Robert Millikan ...
