Observational constraints on viscous free-$\gamma$ fluid in $f(Q)$ gravity

Simran Arora, Sai Swagat Mishra, P. K. Sahoo

We study the late-time cosmological dynamics of a spatially flat FLRW universe in the framework of $f(Q)$ gravity, where $Q$ denotes the nonmetricity scalar. The matter sector is m…
