The sharp rise of velocity dispersion line_3: observed near its center indicates either that it is in the line_4: act of collapse or that it has a black hole at its center. line_5: No one knows how small its true core is. The high resolution line_6: of the FOC f/96 camera offers the best opportunity to line_7: "resolve" these problems. ! ! end of abstract general_form_proposers: lname: KING fname: IVAN mi: R. inst: UC, BERKELEY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: On the central region of M15, near-UV imaging, line_2: f/96, F342W, 1500 s line_3: in case of saturation at the center, an additional exposure: line_4: f/96, F342W+F2ND, 300 s line_5: The choice of near-UV is to suppress the bright stars as line_6: much as possible. ! question: 4 section: 1 line_1: resolving power ! question: 7 section: 1 line_1: To be done on UC Berkeley Astronomy facilities.
