Spectroscopic Investigation of Nebular Gas (SING): instrument design, assembly and testing
On demand | Presented live 17 June 2024 
Abstract
The Spectroscopic Investigation of Nebular Gas (SING), a near-ultraviolet (NUV) spectrograph, operates from 1400 Å to 2700 Å with a 3.7 Å spectral resolution and 1.33′ spatial resolution. Its primary objective is to study various sky regions such as interstellar medium (ISM), hot gas in supernova remnants (SNR), warm gas in planetary nebulae, and cold gas in molecular clouds. It has a 298-mm aperture telescope feeding a long slit UV spectrograph with a dumbbell slit and holographic grating. SING is designed to be mounted on a stable space platform for scanning mode of observation. This article summarizes SING’s design, calibration, and initial performance.

Bharat Chandra P is a PhD student at the Indian Institute of Astrophysics (IIA). He received his MTech degree in astronomical instrumentation from Calcutta University in 2019. His research interests are UV instrumentation, high-altitude ballooning, and optoelectronic instrument design. He has worked on the StarberrySense, a Raspberry Pi-based star sensor flown on the experimental module on the 4th stage of the PSLV C-55. He is currently working on the development of SING, A UV spectrograph which focuses on studying extended objects like interstellar medium (ISM), supernova remnants and planetary nebulae.
