A class of dilaton-electrovacuum radiating solutions with a trivial axion, previously found by G\\\"uven and Y\\\"or\\\"uk, is re-derived in a simpler manner and its causal structure is clarified. It is shown that such dynamical spacetimes featuring apparent horizons do not possess a regular light-like past null infinity or future null infinity, depending on whether they are radiating or acc","authors_text":"Jorge V.
