“The past, present, and future of the Hubble tension”: We interviewed cosmologist Daniel Scolnic for his plenary talk at the upcoming #AAS242!
UR: GRBs – New Standard Candles for Cosmology
Hyper accreting black holes? Highly magnetised neutron stars? What is behind the most powerful explosions in space and how can we use them to measure the largest distances? Recently published population study of gamma-ray bursts light curves that addresses these questions.
Understanding the music of Delta Scuti stars with TESS
The structure of oscillations in intermediate mass stars has eluded astronomers, until now.
Leavitt’s Standard Candles
Happy International Women’s Day. This astrobite investigates how astronomer Henrietta Swan Leavitt’s work changed our understanding of the size of the universe!
Type Ia Supernovae Could Use Some More Color
Including the color of the local environments of Type Ia supernovae in our analyses could help us use them as more precise cosmological tools.
Gaia and the Red Clump
How to calibrate red clump stars as standard candles using a hierarchical probabilistic model.
