DISTORTION (Detection of Spectral signaTures of cOsmic baRyon evoluTION) is an experimental astronomy group at the Raman Research Institute, Bangalore, India. Our team brings together astronomers, graduate students, engineers and project students, all working towards the goal of building precise spectral radiometers to detect weak spectral distortions in the Cosmic Radio and Microwave Backgrounds arising from the Epochs of Recombination all the way to Reionization. The two experiments spearheading this effort are APSERa and SARAS. A description of the science motivating these experiments is here.
