Standardizing Standard Candles: Exploring the (lack of a) Bias in Cosmological Distance Measurements
Today’s paper tests some recent claims that there is a bias in cosmological distance measurements!
Observing the Universe’s Teenage Angst with Dropout Galaxies and CMB Lensing
In today’s bite, we explore a new method for studying how structure grows during the Universe’s formative teenage years, using rebellious dropout galaxies and peer-pressured CMB photons.
Testing cosmology with galaxy motions: what we can learn from measurements of the bulk flow
In today’s Astrobite, we discuss how the motions of galaxies may indicate the presence of large structures in the nearby Universe and put the Lambda-CDM model to the test.
Not-So Standard Candles: How a Bias in Distance Calculations Impacts Our Understanding of Dark Energy
Today’s paper explores how a potential bias in the way we calculate the distance to galaxies impacts our understanding of dark energy.
What can ionised bubbles tell us about the expansion of the universe?
Early galaxies create bubbles of ionised gas around them. Measuring their sizes could provide key insights into cosmology.
So… Are Black Holes Dark Energy?
In today’s bite, we investigate a controversial paper from two years ago, tracing its origins and attempting to finally answer the question: are black holes dark energy?
