Things that go “chirp” in the night
Today’s paper talks about the not-yet-observed electromagnetic counterparts to gravitational waves
Super Star Clusters Far Far Away
Gravitational lensing allows us to look out to cosmological distances. This time we see super star clusters!
Gemstones askew in the heavens
Gravitational lenses provide an opportunity to study distant galaxies in detail. In today’s article we explore an example of how these phenomena are contributing to our understanding of galaxy evolution.
Lensed Substructures
Many dark galaxies may be hiding unseen in the universe—but we still might be able to detect them. Here’s how.
Emergent Gravity faces its First Test in Galaxy Lensing
A recently proposed theory of gravity that got the astrophysical community’s attention is put to tests by observations. Does it succeed? Let’s find out!
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.
