Standard Siren Updates from the Latest LIGO-Virgo Gravitational-Wave Catalog
The latest LIGO-Virgo catalog presents a new set of ‘standard siren’ events that can be used to study the cosmic history of our universe. Read more…
Turning on the Lights – Simulated Modeling of the Sources of Cosmic Reionization
Today’s paper investigates whether it really matters how stars and galaxies cause cosmic reionization.
A-void-ing the CMB cold spot
The cold spot is a strange feature in the CMB that has puzzled astronomers for years. Today’s authors use gravitational lensing to find at least a partial cause: A giant supervoid extending 1.8 billion light years!
Taking a Thumb off the Scale – Reevaluating Cosmological Neutrino Mass Bounds
Massive neutrinos are a thorn in the side of both the Standard Model and ΛCDM – today’s paper reconsiders what we can learn about them from some cosmological data!
Adversarial Networks, Collaborative Cosmology
Can fake data help to make real computational gains? In today’s paper, the authors describe using machine learning to boost the resolution of cosmological simulations.
Real (cosmological) information from simulated maps
Today’s paper proposes a machine learning method to recover fundamental cosmological parameters directly from sky maps. Will gastrophysics get in the way?
