Astrophysics, Gravitational Wave Physics and Cosmology are closely related fields pertaining to the present status of the universe (Astrophysics) and its early history (Cosmology). Gravity, of course, plays a dominant role in the formation and current state of the universe and, and the observation of gravitational waves by LIGO in 2015 solidified the study of Gravitational Wave Physics. Following this initial detection of gravitational waves, the subsequent observation of the electromagnetic output from neutron star binary collisions has opened the door to multi-messenger astrophysics, where a single astrophysical event is observed in a wide-range of electromagnetic frequencies as well as by its emission of gravitational waves. Astrophysics, the study of black holes, neutron stars, gamma ray bursts, and other novel physical objects and processes in the universe, has seen tremendous improvement in the capabilities of observational techniques in the last 10 to 20 years. New generations of Cosmic Microwave Background (CMB) experiments are planned and being built, which will lead to ever more precise measurements of the CMB and the imprint of the early universe that it carries.
