The function for starting an application is defined in nrf_bootloader_app_start.h:

/**@brief Function for starting another application (and aborting the current one).
 *
 * @details This function uses the provided address to swap the stack pointer and then load
 *          the address of the reset handler to be executed. It checks the current system mode
 *          (thread/handler). If in thread mode, it resets into the other application.
 *          If in handler mode, isr_abort is executed to ensure that handler mode is left correctly.
 *          It then jumps into the reset handler of the other application.
 *
 * @note This function will never return, but issues a reset into the provided application.
 *
 * @param[in]  start_addr  Start address of the other application. This address must point to the
               initial stack pointer of the application.
 *

void nrf_bootloader_app_start(uint32_t start_addr);

& is called at the end of the main() function in main.c:

// Either there was no DFU functionality enabled in this project or the DFU module detected
// no ongoing DFU operation and found a valid main application.
// Boot the main application.
nrf_bootloader_app_start(MAIN_APPLICATION_START_ADDR);
