Hello everyone,
my name is Michael Lehmann. I’m an independent cosmologist and the author of Relaxation-Driven Cyclic Cosmology (RDCC), a minimal one-parameter CPT-symmetric framework that makes sharp, correlated predictions for late-time observables such as fσ₈ and weak lensing.
I have been following the LSST project and the DESC forecasting efforts with great interest. The unprecedented precision of LSST data will allow powerful tests of beyond-ΛCDM models, and I believe RDCC could offer an interesting and falsifiable test case in that context.
I have just joined the forum and would be grateful for any advice on how independent researchers can best contribute to the community and the forecasting work.
Thank you for this open and collaborative space. I look forward to learning from you and hopefully contributing something useful.
Best regards,
Michael Lehmann
