Wavelength calibration of a tunable spatial heterodyne spectrometer

Nirmal, K; Sridharan, R; Sriram, S; Ambily, S; Mathew, J; Mayuresh, Sarpotdar; Murthy, J; Binukumar, G; Safonova, M (SPIE-The International Society for Optical Engineering, 2018-07-06)

Spatial Heterodyne Spectroscopy (SHS) is a relatively novel interferometric technique similar to Fourier transform spectroscopy and shares design similarities with a Michelson Interferometer. An Imaging detector is used ...
Wide-field ultraviolet imager for astronomical transient studies

Mathew, J; Ambily, S; Prakash, A; Mayuresh, Sarpotdar; Nirmal, K; Sreejith, A. G; Safonova, M; Murthy, J; Brosch, N (Springer, 2018-04)

Though the ultraviolet (UV) domain plays a vital role in the studies of astronomical transient events, the UV time-domain sky remains largely unexplored. We have designed a wide-field UV imager that can be flown on a range ...
β-SGP: Scaled Gradient Projection with β-divergence for astronomical image restoration

Gondhalekar, Y; Safonova, M; Saha, S (Elsevier B.V., 2023-07)

Image restoration in astronomy has been considered a vital step in many ground-based observational programs that often suffer from sub-optimal seeing due to atmospheric turbulence, distortion of stellar shapes due to ...
