Alex Reeves @cosmicalex.bsky.social · 15/03/2025We also find that allowing for a DDE background both weakens constraints and pushes the posterior to higher masses allowing for a ~2 sigma constraint in our baseline data combination with Planck PR4. 000
Alex Reeves @cosmicalex.bsky.social · 15/03/2025We find that the consistent addition of low-z data (KiDS/BOSS/CMB lensing) pushes DDE constraints back towards a cosmological constant. We do not include Supernovae in this analysis (but we are currently working on this!) 000
Alex Reeves @cosmicalex.bsky.social · 15/03/2025About month ago we put our multiprobe paper on the arXiv! If you've ever wondered: - what happens when dynamical dark energy models are confronted with combined probes? - what a consistent multiprobe framework means for neutrino masses? Then this could be for you! arxiv.org/abs/2502.01722arxiv.orgTuning the cosmic instrument: robust cosmology through combined probesAs wide-field surveys yield increasingly precise data, multiprobe analyses offer significant advantages. In this work, we use our previously developed framework for jointly analyzing cosmic microwave ... 262
