Optimization of Antenna Performance for Global 21-cm Observations and Verification Using Scaled Copies
O. A. Restrepo, F. I. Lucero, G. Chaparro +5
The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although…
A Bayesian Monte Carlo assessment of orbital stability in the late stages of planetary system formation
Jassyr Salas, Frank Bautista, Germán Chaparro
The final orbital configuration of a planetary system is shaped by both its early star-disk environment and late-stage gravitational interactions. Assessing the relative importance…
Conditions for visual and high-resolution bistatic radar observations of Apophis in 2029
Agustín Vallejo, Jorge I. Zuluaga, Germán Chaparro
On April 13, 2029, asteroid Apophis will pass within six Earth radii (31000 km above surface), in the closest approach of this asteroid in recorded history. This event provid…
A Zero-Gravity Instrument to Study Low Velocity Collisions of Fragile Particles at Low Temperatures
D. M. Salter, D. Heißelmann, G. Chaparro +14
We discuss the design, operation, and performance of a vacuum setup constructed for use in zero (or reduced) gravity conditions to initiate collisions of fragile millimeter-sized p…
