Exotic forms of matter such as carbon nanofoams, hexalambdas, super-hypernuclei, strange stars, pentaquarks, color-balls, etc. and their relations to current problems in cosmo-particle physics such as dark matter and energy are discussed in…
This note chronicles the early steps and incidences from over four decades ago, that gave a kickstart to research on the now prominent subclass of radio galaxies, called 'Gigahertz-Peaked-Spectrum' (GPS) sources. In this first-hand account,…
The most recent observational and theoretical results in the rapidly expanding field of high-energy gamma-ray astrophysics were discussed at the international conference ``Gamma-2024'' that took place in Milano in September 2024. This…
Despite an intense theoretical and experimental effort over the past decade, observations of the extragalactic radio background at multiple frequencies below 10 GHz are not understood in terms of known radio sources, and may represent a…
