Research on black holes and neutron stars is an active area of study in Cornell Astronomy. A large numerical relativity group is devoted to computing the merger of binary systems containing two black holes, one black hole and one neutron star or two neutron stars.
CCAPS Research Areas
Cosmology and the Distant Universe
Cosmology is the study of the evolution of the Universe. At Cornell we study all aspects of cosmology, ranging from the physics of inflation in the very early Universe to the development of large scale structure at modest redshift to the underlying cause of the present phase of accelerated expansion. Our dual goals are to understand basic physical principles and to identify specific observations to test theoretical ideas.
Disks and Jets
In young forming stars, disks form from contracting gas clouds as part of the process of star formation and jets emanating from the disk-star interaction play an important role. Planets form from and within these disks.
Extreme Physics and Astrophysics of Compact Objects
Stars are the exotic end-products of stellar evolution. With masses ranging from 1.2 to 2.0 solar masses but radii as small as 10 km, their interiors approach nuclear densities and provide laboratories for the behavior of matter at extremes of temperature and pressure that cannot be replicated on Earth.
Galaxies Across the Universe
Cornell astronomers study the history and evolution of galaxies across the universe and throughout cosmic time, using both ground- and space-based telescopes spanning the full wavelength range of the electromagnetic spectrum
Planetary Exploration and Exoplanets
Planetary science is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history.
