How a Middleweight Black Hole is Created

  A new model co-developed by BMCC Science Professors Saavik Ford and Barry McKernan shows how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts. This simulated image shows the interaction between a massive gas giant planet (comparable in mass to Jupiter) and a surrounding protoplanetary disk of [continue reading]
