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.
Cepheid yourself – confirming tensions in the Hubble expansion
New observations of pulsing variable stars weigh in on the Hubble tension. Find out how in this Astrobite!
The Search for Black Hole Teenagers
The discovery of medium-sized black holes allow us to trace the history of the giant black holes in the center of galaxies.
Looking Deeper at Milky Way Satellite Dwarf Galaxy Candidates
Four new Milky Way dwarf satellite candidates were discovered in 2015 using the Dark Energy Survey. Fainter imaging data are used to further investigate their exact nature.
Reading the Epic of Reionization
Observations of dim galaxies lensed by foreground clusters provides a way of measuring the progression of reionization.
Can we a-void the Hubble tension with local voids?
Cosmologists revisit an idea for addressing the Hubble tension: that a local void is messing with our measurements along the cosmic distance ladder.
