A dead-cone structure with an opening angle $\\theta^2_0 \\approx 2(1-z)/(zLE)$ for gluons with fractional energy $z$ arises from the Landau-Pomeranchuck-Migdal (LPM) interference. In a medium where the gluon's dielectric constant is $\\epsilon >1$, the LPM interference pattern is shown to become Cherenkov-like with an increased opening angle determined by the dielectric constant $\\cos^2\\theta_c=z+(1-z)/\\epsilon$.
