A new broadband atmospheric dispersion corrector for HROS-TMT
Manjunath Bestha, Thirupathi Sivarani, Bachar Wehbe +7
Atmospheric dispersion causes light from celestial objects with different wavelengths to refract at varying angles as it passes through Earth's atmosphere. This effect results in a…
Atmospheric Dispersion Measurement at Hanle Site
Manjunath Bestha, Sivarani Thirupathi, Athira Unni +2
Atmospheric dispersion introduces wavelength-dependent effects that significantly impact ground-based observations, particularly in slit- and fibre-fed spectroscopic studies. These…
Design overview of the fiber feed for the Hobby-Eberly telescope's HRS
Devika K Divakar, Phillip MacQueen, Joseph Strubhar
We present the redesign of the fiber feed for the High Resolution Spectrograph (HRS) at the Hobby Eberly Telescope (HET). The upgrade incorporates a static atmospheric dispersion c…
Possibilities of Identifying Members from Milky Way Satellite Galaxies using Unsupervised Machine Learning Algorithms
Devika K Divakar, Pallavi Saraf, Sivarani Thirupathi +1
A detailed study of stellar populations in Milky Way (MW) satellite galaxies remains an observational challenge due to their faintness and fewer spectroscopically confirmed member…
