Hu-Sawicki Gravity in a Non-Flat Universe: Constraints from DESI-DR2, BBN, and Type Ia Supernovae
Saurabh Verma, Manish Yadav, Archana Dixit +2
Late-time cosmic acceleration is conventionally ascribed to a cosmological constant, though CDM continues to face several theoretical difficulties that keep alternative gravity…
