Cosmological Parameters from Observations of Galaxy Clusters
Allen, Steven W.; Evrard, August E.; Mantz, Adam B.
Studies of galaxy clusters have proved crucial in helping to establish the standard model of cosmology, with a Universe dominated by dark matter and dark energy. A theoretical basis that describes clusters as massive, multicomponent, quasi-equilibrium systems is growing in its capability to interpret multiwavelength observations of expanding scope…
The Chemical Composition of Comets—Emerging Taxonomies and Natal Heritage
Mumma, Michael J.; Charnley, Steven B.
Cometary nuclei contain the least modified material from the formative epoch of our planetary system, and their compositions reflect a range of processes experienced by material prior to its incorporation in the cometary nucleus. Dynamical models suggest that icy bodies in the main cometary reservoirs (Kuiper Belt, Oort Cloud) formed in a range of…
