The age of cross-correlations
When two observations share some common information, they can be “cross-correlated” to extract it. In today’s example, we discover what the matter halos and energetic phenomena in the Universe have in common through a cross-correlation.
Gravitational waves and the need for fast galaxy surveys
In the next few years, gravitational wave detectors are expected to start finding mergers of compact objects. But their resolution is limited to large areas of the sky. Fast galaxy surveys are needed to aid in the task of locating the source more precisely, but how fast can they go?
Void cosmology
The distribution of matter in the Universe has much to say about its constituents and evolution. Can the distribution of voids also help us understand the Universe?
Cosmic rays on the sky – where do they come from?
Cosmic rays hit the Earth and produce showers of particles that can be detected on the ground. Understanding where these cosmic rays come from can help scientists pin down their sources and construct models for the magnetic field in our neighborhood.
