Perspectives on Gamma-Ray Burst Physics and Cosmology with Next Generation Facilities [PDF]

open access: yes, 2016
High-redshift Gamma-Ray Bursts (GRBs) beyond redshift $\sim6$ are potentially powerful tools to probe the distant early Universe. Their detections in large numbers and at truly high redshifts call for the next generation of high-energy wide-field ...

A UV-visible prime focus camera for the Keck telescopes [PDF]

open access: yes, 2020
Many areas of astronomical research rely on deep blue wide-field imaging. Mauna Kea enjoys the very best UV transparency from the ground and the Keck telescopes with 10 meter f/1.75 primaries are well suited to a prime focus camera with a large angular ...

Optimization of grazing incidence mirrors and its application to surveying X-ray telescopes

open access: yes, 2001
Grazing incidence mirrors for X-ray astronomy are usually designed in the parabola-hyperbola (Wolter I) configuration. This design allows for optimal images on-axis, which however degrade rapidly with the off-axis angle.

Wide field interferometric imaging with single-mode fibers [PDF]

open access: yes, 2002
Classical single-mode fiber interferometers, using one fiber per aperture, have very limited imaging capabilities and small field of view. Observations of extended sources (resolved by one aperture) cannot be fully corrected for wavefront aberrations ...

A New Type of Atmospheric Dispersion Corrector Suitable for Wide-Field High-Resolution Imaging and Spectroscopy on Large Telescopes

open access: yesApplied Sciences, 2021
Atmospheric dispersion produces spectral elongation in images formed by land-based astronomical telescopes, and this elongation increases as the telescope points away from the zenith.
