Ultraviolet and optical view of galaxies in the Coma Supercluster [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 The Coma supercluster (100 Mpc) offers an unprecedented contiguous range of environments in the nearby Universe. In this paper we present a catalogue of spectroscopically confirmed galaxies in the Coma supercluster detected in the ultraviolet (UV) wavebands.

BMC Ophthalmology, 2017 Background Intrascleral fixation of an intraocular lens (IOL) is used in eyes that lack capsular support. The aim of the study is to determine whether a larger optical diameter IOL will decrease the higher-order aberrations (HOAs) when the haptics are ...

Validation of Mahajan's formula for scaling ocular higher-order aberrations by pupil size
Indian Journal of Ophthalmology, 2020 Purpose: Zernike polynomials for describing ocular higher order aberrations are affected by pupil aperture. The current study aimed to validate Mahajan's formula for scaling Zernike polynomials by pupil size.

Design Considerations for Large Detector Arrays on Submillimeter-wave Telescopes [PDF]
, 2000 The emerging technology of large (~ 10,000 pixel) submillimeter-wave bolometer arrays presents a novel optical design problem---how can such arrays be fed by diffraction-limited telescope optics where the primary mirror is less than 100,000 wavelengths ...

Optical Observations of Serendipitous Exosat Sources in the Coma Cluster
Space Science Reviews, 1985 A ∼7 hour observation of the central part of the Coma Cluster of galaxies has been performed with the EXOSAT LE telescopes and CMA detectors. Five serendipitous sources are detected within the inner 35 arcmin radius of the field. Optical spectroscopy demonstrates that at least three of these are background AGN not associated with the cluster.

Methods of optimizing X-ray optical prescriptions for wide-field applications [PDF]
, 2010 We are working on the development of a method for optimizing wide-field X-ray telescope mirror prescriptions, including polynomial coefficients, mirror shell relative displacements, and (assuming 4 focal plane detectors) detector placement along the ...
