Observations of Binary Stars with the 1.3-m Devasthal Fast Optical Telescope Using Speckle Interferometry: An Attempt
Km Nitu Rai, Arjun Dawn, Neelam Panwar +3
We present a feasibility study of implementing optical interferometry and speckle techniques with the 1.3-m Devasthal Fast Optical Telescope (DFOT) at Aryabhatta Research Institute…
Stellar Multiplicity via Speckle Interferometry with the 3.6 m Devasthal Optical Telescope
Km Nitu Rai, Neelam Panwar, Jeewan C Pandey +3
Conventional ground-based optical telescopes, even those with large apertures, primarily observe stars, close binaries, and multiple systems as unresolved point sources through pho…
Radial Pulsations in Polaris: A Secondary Science Application of Cherenkov Telescopes via Intensity Interferometry
Km Nitu Rai, Prasenjit Saha, Subrata Sarangi
Ground-based Cherenkov telescopes, which are typically inoperative during moonlit nights for gamma-ray observations, offer a valuable opportunity during this time for secondary sci…
Generative AI for image reconstruction in Intensity Interferometry: a first attempt
Km Nitu Rai, Yuri van der Burg, Soumen Basak +2
In the last few years, Intensity Interferometry (II) has made significant strides in achieving high-precision resolution of stellar objects at optical wavelengths. Despite these ad…
Interference with (Pseudo) Thermal Light; The Hanbury Brown and Twiss Effect
Km Nitu Rai, Soumen Basak, Subrata Sarangi +1
The correlation of light from two sources leads to an interference pattern if they belong to a specific time interval known as the coherence time, denoted as . The relationship…
