    "abstract": "In the jet quenching model, we have analysed the PHENIX data on nuclear\nmodification factor of $\\pi^0$, in Au+Au collisions at $\\sqrt{s}$=200 GeV, and\nextracted the initial gluon density of the medium produced. In jet quenching,\npartons lose energy in the medium, depending on the medium density as well as\non the in-medium path length. Systematic analysis indicate that in most central\n(0-10% centrality) collisions, medium density is very large $dN_g/dy \\sim$\n2150. Medium density decreases exponentially as the collision centrality\ndecreases and in very peripheral (70-92% centrality) collisions, $dN_g/dy \\sim$\n3. Initial energy density of the medium also decreases smoothly from\n$\\epsilon_0 \\sim$ 20 $GeV/fm^3$ in most central collisions to $\\epsilon_0 \\sim$\n3 $GeV/fm^3$ in most peripheral collisions. Very large $dN_g/dy$ or\n$\\epsilon_0$ indicate very dense matter formation in central Au+Au collisions.",
