Is Dark Energy Dynamical in the DESI Era? A Critical Review
Salvatore Capozziello, Himanshu Chaudhary, Tiberiu Harko +1
We investigate whether the recent DESI DR2 measurements provide or not evidences for dynamical dark energy by exploring the CDM model and its extensions with free $\sum m_ν…
Primordial black hole dark matter from ultra-slow-roll inflation in Horndeski gravity
