A multi-functional fiber positioning system for Extremely Large Telescopes
Manjunath Bestha, T. Sivarani, Arun Surya +7
We present a conceptual design for a fiber positioning system for multi-object high-resolution spectroscopy, designed to be compatible with the upcoming large telescopes with a wid…
Atmospheric dispersion corrector for a multi-object spectroscopic mode of HROS-TMT
Manjunath Bestha, Amirul Hasan, Devika Divakar +6
Highly multiplexed spectroscopic surveys have changed the astronomy landscape in recent years. However, these surveys are limited to low and medium spectral resolution. High spectr…
In orbit performance of UVIT over the 5 years
S. K. Ghosh, P. Joseph, A. Kumar +21
Over the last 5 years, UVIT has completed observations of more than 500 proposals with ~ 800 unique pointings. In addition, regular planned monitoring observations have been made a…
Additional Calibration of the Ultra-Violet Imaging Telescope on board AstroSat
S. N. Tandon, J. Postma, P. Joseph +20
Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. (2017). The results reported earlier were based on the ground…
Prospect for UV observations from the Moon. III. Assembly and ground calibration of Lunar Ultraviolet Cosmic Imager (LUCI)
Joice Mathew, B. G. Nair, Margarita Safonova +14
The Lunar Ultraviolet Cosmic Imager (LUCI) is a near-ultraviolet (NUV) telescope with all-spherical mirrors, designed and built to fly as a scientific payload on a lunar mission wi…
Design and modeling of a tunable spatial heterodyne spectrometer for emission line studies
Nirmal Kaipachery, Sridharan Rengaswamy, Sripadmanaban Sriram +6
Spatial Heterodyne Spectroscopy (SHS) is a relatively novel interferometric technique similar to the Fourier transform spectroscopy with heritage from the Michelson Interferometer.…
