The light from a star is not constant, it varies as the layers of hot material move back and forth, clump and disperse. Most of these vibrations are visible, detectable, and well understood. But some bizarre new vibration is happening in stars, for which we have no clear path to an explanation.
Trying to find the most massive galaxy cluster in the night sky can be hard. Comparing predictions of these masses to observed clusters? Even harder. An insight into the world of Halo Mass Functions and their tail-ends.
Today’s paper constrains cosmological parameters from one of the largest ground-based astrophysical surveys ever undertaken – DES. An insight into their first-year’s data analysis, released in August 2017.
Today’s paper takes you back to the time when anisotropies in the Cosmic Microwave Background first shaped Observational Cosmology into the field it is today.
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
In today’s bite, we push Bayes’ theorem to the limits, in an attempt to make predictions about the prevalence of habitable planets covered in ocean.
