The lecture for the February meeting is The Nicer X-Ray Telescope After Two Years.

The Neutron Interior Composition Explorer is an instument mounted on the ISS. It has unique X-Ray measurement capabilities that were designed to produce high precision measurments of the radius and mass of neutron stars. Such measurements are key to the understanding of the interior composition and equation of state of Neutron Stars. While their name implies that they are made of neutrons there is a great deal of uncertainty as to what actually is going on inside them. Is there strange matter in their cores? Are there hadron droplets in the outer shells? And so on. NICER was designed to provide (at least partial) answers to these questions.

Thus far NICER has gone through calibration and commisioning trials and has made high precision measurements of the radii and masses of Neutron Stars. Doing so requires sophicated simulations of the (highly curved by gravity) environment and interiors of neutron stars. In addition to its primary goal of thining down the options for the interior behavior of Neutron Stars, NICER has made a number of unique contributions to X-Ray astronomy of Neutron Stars and Black Holes.
