How standardizable of a candle are Type-1a supernovae? Learn how differing initial conditions causing a white dwarf to exceed the Chandrasekhar limit and explode might reconcile independent measurements of the Universe’s expansion rate and history.
The oldest objects in the universe weigh in on the heated debate over the “Hubble Tension,” disagreements on the expansion rate of the universe.
Do you like fast radio bursts but hate the Hubble tension? If so, then this paper showing the first measurement of the Hubble constant using FRB observations is for you!
What if we used stars other than Cepheids to measure distances?
The Tip of the Red Giant Branch (TRGB) allows for another H0 measurement to enter the ring. Credit for “H0tTake” goes to the conference “Tensions between the Early and the Late Universe” hosted at the Kavli Institute for Theoretical Physics!
The field of cosmology just can’t seem to agree on a value of the Hubble constant, so astrophysicists attempt to provide a new, independent measurement using strong gravitational lensing.
