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.
Techniques in astrostatistics help astronomers characterize large amounts of data. The authors of today’s astrobite use data-driven astrostatistics to distinguish between populations of hot Jupiters in a sample. It’s a technique that can definitely be put to good use over the next few decades, as oodles of observations pour in from the new telescopes of the 21st century.
Astronomers have found hydrogen contamination in the atmospheres of helium white dwarfs – but where in the world/universe is it coming from?! The authors of today’s astrobite perform statistical tests to see if the source of this pesky hydrogen could be water-bearing rocky bodies out in space.
