🔭 What is Radio Astronomy?
Radio astronomy studies celestial objects through their radio wave emissions, uncovering phenomena invisible in optical light — from pulsars and quasars to the cosmic microwave background and even potential exoplanet signals.

🌐 What is Interferometry?
Interferometry combines data from multiple antennas to create a single, high-resolution image, allowing astronomers to map faint and distant radio sources with exceptional precision.

📊 Data Products and Tools
Radio data are processed using software like AIPS, MIRIAD, CASA, and ezRA, which handle calibration, imaging, and analysis. These tools transform raw signals into scientifically meaningful maps, spectra, and data cubes.

⚙️ CASA (Common Astronomy Software Applications)
The primary software suite for radio data calibration and imaging, used by major telescopes such as ALMA and the VLA, enabling precise processing and visualization.

🛰️ CARTA (Cube Analysis and Rendering Tool for Astronomy)
A modern, GPU-accelerated visualization tool for exploring large multidimensional datasets like spectral line cubes, making data inspection intuitive and interactive.

💡 radio-astro-tools Suite
A collection of Python packages for handling, analyzing, and visualizing radio astronomy data — including spectral-cube, radio-beam, and pvextractor — offering flexible, open-source solutions for modern research workflows.
