Place your bets: LCDM vs. El Gordo
In the most anticipated fight of the cosmic epoch, find out whether the titan cluster El Gordo is poised to defeat our reigning cosmological model.
The starry, dusty origin of a galaxy cluster at z = 4!
We shed some light on the inner workings of an ultra-red, massive cluster core spotted at high redshift!
Running up that hill: are some galaxy clusters moving away faster than others?
We discuss a new way to test the cosmological principle using X-ray studies of galaxy clusters in this Astrobite.
You were cool, Betelgeuse
In this bite, we follow Betelgeuse’s rise to fame (and in magnitude).
Why cosmology is (probably) not behind the curve
A reanalysis of the cosmic microwave background data suggests a slightly more curved Universe than previously measured.
