  "abstract": "The ${^3{\\rm He}}(\\alpha,\\gamma){^7{\\rm Be}}$ and ${^3{\\rm H}}(\\alpha,\\gamma){^7{\\rm Li}}$ astrophysical $S$ factors are calculated within the no-core shell model with continuum using a renormalized chiral nucleon-nucleon interaction. The ${^3{\\rm He}}(\\alpha,\\gamma){^7{\\rm Be}}$ astrophysical $S$ factors agree reasonably well with the experimental data while the ${^3{\\rm H}}(\\alpha,\\gamma){^7{\\rm Li}}$ ones are overestimated. The seven-nucleon bound and resonance states and the $\\alpha+{^3{\\rm He}}/{^3{\\rm H}}$ elastic scattering are also studied and compared with experiment. The low-lying resonance properties are rather well reproduced by our approach. At low energies, the $s$-wave phase shift, which is non-resonant, is overestimated.",
