We present the preliminary results on the first measurements of the low-mass dielectron continuum in Au+Au collisions and the phi meson production measured in Au+Au and d+Au collisions at sqrt{s_NN} = 200 GeV performed by the PHENIX experiment.6 pages, 12 figures, conference proceedings for QNP06 (5-10 June, 2006, Madrid)Nuclear Experimenttext
