Strong field lensing and shadows of $\mathbf{f}(\mathbf{Q},\mathcal{B})$ gravity black holes

Rahul Das, Umananda Dev Goswami

We investigate the strong field lensing of light by black holes (BHs)emerging in $f(Q,\mathcal{B})$ theory of gravity, which is an extension of $f(Q)$ gravity theory by including…
