The Extremely Large Telescope Interferometer
Francisco Prada, Enrique Perez, Sergio Fernandez-Acosta +2
The ELTI concept capitalizes on recent breakthroughs in large-format SPAD (Single-Photon Avalanche Diode) imaging sensors, combining them with the unprecedented collecting area and…
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…
Simulations of astrometric planet detection in Alpha Centauri by intensity interferometry
Km Nitu Rai, Subrata Sarangi, Prasenjit Saha +1
Recent dynamical studies indicate that the possibility of an Earth-like planet around Cen A or B should be taken seriously. Such a planet, if it exists, would perturb the orbi…
Radius measurement in binary stars: simulations of intensity interferometry
Km Nitu Rai, Soumen Basak, Prasenjit Saha
Mass and radius measurements of stars are important inputs for models of stellar structure. Binary stars are of particular interest in this regard, because astrometry and spectrosc…
