There are a lot of (Python) cosmology libraries out there, from big projects -- including Astropy, CLASS, and CAMB-- down to small personal scripts. These libraries perform many of the same tasks, but ...

To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe is gravitationally attracting all the other matter in the universe; ...

Abstract: This paper presents the design of an absorbing ground plane as a solution for ground reflections in 21cm radio cosmology applications. The proposed ground plane is formed by a metamaterial, ...

In 1989, Rocky Kolb and Mike Turner published The Early Universe – a seminal book that offered a comprehensive introduction to the then-nascent field of particle cosmology, laying the groundwork for a ...

The Gruber Foundation today recognized four scientists who have made significant contributions to the fields of cosmology, genetics, and neuroscience. Recipients of the Gruber International Prize ...

With the increasing power of telescopes and computers, cosmologists today are pushing the boundaries of human knowledge about the universe, seeing further and simulating more accurately that ever ...

About a year after launching into orbit around the Sun, the James Webb Space Telescope began imaging an abundance of little red dots, which scientists called, um, “little red dots.” I know—not only is ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say. When you ...
