    "abstract": "We theoretically study the effect of ultraslow group velocities on the\nemission of Vavilov-Cherenkov radiation in a coherently driven medium. We show\nthat in this case the aperture of the group cone on which the intensity of the\nradiation peaks is much smaller than that of the usual wave cone associated\nwith the Cherenkov coherence condition. We show that such a singular behaviour\nmay be observed in a coherently driven ultracold atomic gas.",
