Electromagnetic radiation astronomy is a research area focused on observing and interpreting astrophysical phenomena through their emission, absorption, and scattering of electromagnetic radiation across the entire spectrum, from radio waves to gamma rays. It encompasses the development and use of ground-based and space-borne telescopes, detectors, and instrumentation optimized for specific wavelength ranges, along with calibration, data reduction, and spectral, temporal, and imaging analysis techniques. The field integrates radiative transfer, plasma physics, and atomic and molecular processes to infer physical conditions, kinematics, composition, and magnetic fields in cosmic sources, and underpins multiwavelength and multi-messenger studies of the universe.
Using NASA's Chandra and ESA's XMM-Newton space observatories, Indian astronomers have explored the population of ultraluminous X-ray sources in the galaxy NGC 5813, which resulted in the detection of a new source of this ...
Fast radio bursts (FRBs) last around a millisecond, and in doing so, encode otherwise unattainable information on the plasma which permeates our universe, providing insights into magnetic fields and gas distributions.
