| contents | In this work, we systematically study the electromagnetic properties including the M1 radiative decay widths and the magnetic moments of the isoscalar $Ξ_{c c} D^{(*)}$, $Ξ_{cc}D_{1}$, and $Ξ_{cc}D_{2}^{*}$ triple-charm molecular-type pentaquark candidates, where we adopt the constituent quark model and consider both the $S$-$D$ wave mixing effect and the coupled channel effect. Our numerical results suggest that the M1 radiative decay widths and the magnetic moments of the isoscalar $Ξ_{c c} D^{(*)}$, $Ξ_{cc}D_{1}$, and $Ξ_{cc}D_{2}^{*}$ triple-charm molecular-type pentaquark candidates can reflect their inner structures, and the study of the electromagnetic properties is the important step to construct the family of the triple-charm molecular-type pentaquarks. With the accumulation of the experimental data during the high-luminosity phase of LHC, we expect that the present work combined with the corresponding mass spectrum information can encourage the experimental colleagues at LHCb to focus on the isoscalar $Ξ_{c c} D^{(*)}$, $Ξ_{cc}D_{1}$, and $Ξ_{cc}D_{2}^{*}$ triple-charm molecular-type pentaquark candidates. |
