Congruences for overpartitions with ${\ell}$-regular nonoverlined parts

Let $\overline{R_{\ell}^{*}}$ denote the number of overpartitions of $n$ where nonoverlined parts are $\ell$-regular and overlined parts are unrestricted. In this paper, we establish several Ramanujan like congruences and infinite families of congruences for $\overline{R_{\ell}^{*}}$ for $\ell=2k, 5, 6$ and $8k$. For example, for all $n\geq 0$ $$\overline{R_{184}^{*}}(16n+15)\equiv 0\pmod{1472}.$$
