Title: A NICER view of neutron stars 

Abstract: NICER, the Neutron Star Interior Composition Explorer, is an X-ray telescope on the International Space Station. Its mission is to study the nature of the densest matter in the Universe, found in the cores of neutron stars.  NICER uses Pulse Profile Modeling, a technique that exploits relativistic effects on X-rays emitted from the hot magnetic polar caps of millisecond pulsars.   The technique also lets us map the hot emitting regions, which form as magnetospheric particles slam into the stellar surface.  I will present NICER's latest results - including a measurement of the radius for the highest mass pulsar known - and discuss the implications for our understanding of ultradense matter, pulsar emission, and stellar magnetic fields.
