The Bullet Cluster – A Smoking Gun for Dark Matter!
A classic paper on dark matter is brought to ‘light’ in this bite, discussing a discovery that provides one of the best evidences we have for non-baryonic matter in the universe.
Now You See Them, Now You Don’t – How to Find Distant Galaxies
A look at a classic paper exploring a novel technique to select distant galaxies by waiting for them to drop out of the spectra…
The Predictor of Pulsar Timing
Since gravitational waves are now on the tip of every astronomer’s tongue, today’s post looks back at a classic paper’s key result that is quintessential in the search for gravitational waves using pulsar timing arrays.
Leaving on a jet stream
Through tangled magnetic fields, super massive black holes and at least one otter, we explore how the phenomenal jets launched from the centre of galaxies are created.
Galaxy Clusters, Cosmology, and Beethoven’s No. 6
This article explores the utility of galaxy clusters as a probe for precision cosmology, by reviewing some of the seminal literature in the field. Somewhere along the way, a symphony is heard.
The Lives of the Longest Lived Stars
Heavy stars live like rock stars: they live fast, become big, and die young. Low mass stars, on the other hand, are more persistent, and live longer. Fusing hydrogen slow and steady wins the stellar age-race.
