▼a The minor bodies of the Solar System encode information about the formation and dynamical evolution of the Solar System. The bodies beyond Neptune, trans-Neptunian objects (TNOs), serve as dynamical tracers of gravitational interactions between these bodies and the giant planets. By studying their orbits and surface properties, as both individual objects and as populations, we paint a more complete picture of the formation and evolution history of the Solar System. This thesis uses data from the Dark Energy Survey, a wide-area and relatively deep cosmological survey, to study both individual minor bodies discovered by the survey and populations implied by detected objects.The largest TNOs provide a window into the formation environment in the distant Solar System because they have sufficient gravity to retain at least some of their original volatiles and ices. While most TNOs are too distant, and therefore too faint, to obtain reflectance spectra that would enable detailed study of their surface compositions, a measurement of their albedo can still provide insight. We use measurements from DES and ALMA to calculate the diameter and albedo of the first dwarf planet candidate detected using DES at D = 635+57-61혻(stat)+32-39(sys) km and pV = 13.1+3.3-2.4혻(stat)+2.0-1.4 (sys), implying a rocky-ice composition.All surveys suffer from inherent biases due simply to the design of the survey. The "survey simulator" approach to debiasing survey detections has gained traction in recent years. I describe the design of the DES survey simulator and use it to characterize the discoveries of interesting TNOs by DES. I describe the simulator's use in a population study of Neptune Trojans, culminating in a population estimate of 162 +/- 73 L4 Neptune Trojans with Hr < 10 (consistent with previous estimates). Finally, I use the simulator to debias the orbital clustering of the most distant TNOs discovered by DES. Objects in this class have been used to argue for the existence of a distant massive planet in the Solar System. I find that DES is unable to distinguish between additional planet scenario and the scenario in which the observed objects originate from a uniform underlying distribution. |
