New Cosmological Detectives: Using FRBs to Constrain the Diffuse Gas Fraction
With an ideal dataset of many localized FRBs, how can the diffuse gas fraction in the IGM be constrained?
Explaining Ancient Stellar Populations
Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
TLDR: the TRGB gives us another H0tTake!
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!
Learning about galaxy evolution with naked red nuggets
A unique population of galaxies may hold the keys to discovering how star formation stops happening in older galaxies.
H0ly Cow! A New Measurement of the Hubble Constant
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.
Glimpsing the fingerprints of gravitational waves in the early universe
Scientists can use neural networks to glimpse gravitational wave fluctuations from the early universe.
