With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
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!
A unique population of galaxies may hold the keys to discovering how star formation stops happening in older galaxies.
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.
Scientists can use neural networks to glimpse gravitational wave fluctuations from the early universe.
