Gaussian phase autocorrelation as an accurate compensator for FFT-based atmospheric phase screen simulations
Sorabh Chhabra, Jyotirmay Paul, A. N. Ramaprakash +1
Accurately simulating the atmospheric turbulence behaviour is always challenging. The well-known FFT based method falls short in correctly predicting both the low and high frequenc…
Speckle simulation tool for automated modelling of a large range of telescope aperture to fried parameter ratios
Sorabh Chhabra, Abhay A. Kohok, Bhushan S. Joshi +3
The Speckle Imager via MUlti Layer Atmospheric Turbulence Object Reconstructor (SIMULATOR) is a lab-based testbed instrument developed to test for speckle correlation-based techniq…
Spectrograph design for the Asgard/BIFROST spectro-interferometric instrument for the VLTI
Sorabh Chhabra, Michele Frangiamore, Stefan Kraus +4
The BIFROST instrument will be the first VLTI instrument optimised for high spectral resolution up to R=25,000 and operate between 1.05 and 1.7 m. A key component of the instrum…
Beam combiner for the Asgard/BIFROST instrument
Daniel J. Mortimer, Sorabh Chhabra, Stefan Kraus +4
BIFROST will be a short-wavelength ( = 1.0 - 1.7m) beam combiner for the VLT Interferometer, combining both high spatial (/2B = 0.8 mas) and spectral (up to R = 25,000) re…
High spectral-resolution interferometry down to 1 micron with Asgard/BIFROST at VLTI: Science drivers and project overview
Stefan Kraus, Daniel Mortimer, Sorabh Chhabra +10
We present science cases and instrument design considerations for the BIFROST instrument that will open the short-wavelength (Y/J/H-band), high spectral dispersion (up to R=25,000)…
