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…

Simulating the Detection of the Global 21 cm Signal with MIST for Different Models of the Soil and Beam Directivity

Raul A. Monsalve, Christian H. Bye, Jonathan L. Sievers +10

The Mapper of the IGM Spin Temperature (MIST) is a new ground-based, single-antenna, radio experiment attempting to detect the global 21 cm signal from the Dark Ages and Cosmic Daw…

Predicting extragalactic distance errors using Bayesian inference in multi-measurement catalogs

Germán Chaparro Molano, Juan Carlos Cuervo, Oscar Alberto Restrepo Gaitán +1

We propose the use of robust, Bayesian methods for estimating extragalactic distance errors in multi-measurement catalogs. We seek to improve upon the more commonly used frequentis…

Low Dimensional Embedding of Climate Data for Radio Astronomical Site Testing in the Colombian Andes

Germán Chaparro Molano, Oscar Leonardo Ramírez Suárez, Oscar Restrepo +1

We set out to evaluate the potential of the Colombian Andes for millimeter-wave astronomical observations. Previous studies for astronomical site testing in this region have sugges…
