Part 3: Extended Physics Analyses with the DESI DR2 BAO
Today Astrobites is featuring results from the DESI DR2, published today in PRJ! In Part 3, we discuss 2 additional papers using the BAO measurement to perform additional analyses.
Part 1: Key Results from the DESI DR2
Today Astrobites is featuring results from the DESI DR2, published today in PRJ! In Part 1, we cover the key results papers describing their measurements with DR2.
Using Galaxy Halos to Study Baryonic Feedback in FLAMINGO
Today’s authors use FLAMINGO simulations to probe the tension between different observational methods of estimating cosmological parameters.
If primordial black holes are dark matter, would we know?
Today’s paper explores the detectability of primordial black holes as a potential dark matter candidate.
The Continuing Saga of the Not-So-Constant Constant.
The cosmological constant is a constant, right? The word “constant” is right there in the name for goodness sakes. But growing evidence suggests this might not be the case after all. Today’s authors further investigate the DESI analysis pushing our understanding of dark energy.
Using Large-scale structures and gravitational wave sources to measure the expansion rate
In today’s astrobite we explore a new approach that has been developed to measure the Universal expansion rate, involving gravitational waves from merging black holes and the large-scale structure of the Universe.
