Resumen (en)

The 21 cm hydrogen line, caused by the hyperfine transition of neutral hydrogen, provides crucial information about the distribution and motion of interstellar gas in galaxies and the Milky Way. The ability to observe this line with high precision and detail is essential to understanding the evolution of large-scale cosmic structures. The article focuses on the development and construction of an advanced radio telescope, equipped with cutting-edge technologies in detection and signal processing. Featured features include large-diameter antennas, high-sensitivity receiving systems, and advanced algorithms for noise reduction and data analysis. These components allow weak signals from remote regions of the universe to be captured, facilitating detailed mapping of neutral hydrogen.

For the visualization of the SDR (Software Defined Radio) receiver, GNU Radio will be used, a powerful and flexible tool for signal processing. In addition, Python will be used to visualize and analyze the data received from the radio telescope, allowing a detailed and accurate interpretation of astronomical observations.

Resumen (es)

La línea de hidrógeno de 21 cm, originada por la transición hiperfina del hidrógeno neutro, proporciona información crucial sobre la distribución y movimiento del gas interestelar en galaxias y la Vía Láctea. La capacidad de observar esta línea con alta precisión y detalle es esencial para comprender la evolución de las estructuras cósmicas a gran escala. El artículo se centra en el desarrollo y construcción de un radiotelescopio avanzado, equipado con tecnologías de punta en detección y procesamiento de señales. Entre las características destacadas se incluyen antenas de gran diámetro, sistemas de recepción de alta sensibilidad y algoritmos avanzados para la reducción de ruido y análisis de datos. Estos componentes permiten captar señales débiles provenientes de regiones remotas del universo, facilitando el mapeo detallado del hidrógeno neutro.

Para la visualización del receptor SDR (Software Defined Radio), se utilizará GNU Radio, una herramienta poderosa y flexible para el procesamiento de señales. Además, Python se empleará para visualizar y analizar los datos recibidos del radiotelescopio, permitiendo una interpretación detallada y precisa de las observaciones astronómicas.
