"A NICER Era for Neutron Stars and Black Holes"

NASA's Neutron star Interior Composition Explorer (NICER) mission aims to answer longstanding questions about the physics and astrophysics of neutron stars and black holes, among other celestial X-ray sources, using a telescope onboard the International Space Station. Now in a Guest Observer phase, NICER has broadened its scientific horizons while continuing to pursue its legacy-science objective of probing the densest form of matter known, that within the cores of neutron stars. Through high-time-resolution spectroscopy in soft X-rays, NICER is delivering new insights into the extraordinary objects that populate the strong-gravity cosmos. Following a brief overview of the mission, I present a sampling of recent results and describe plans for dramatically improving NICER's responsiveness to time-critical targets of opportunity.
