Alexander Reeves, Simone Ferraro, Andrina Nicola, Alexandre Refregier: Multiprobe constraints on early and late time dark energy https://arxiv.org/abs/2510.06114 https://arxiv.org/pdf/2510.06114 https://arxiv.org/html/2510.06114

We 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.

We 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!)

Tuning the cosmic instrument: robust cosmology through combined probes As 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 ...

About 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!
