Design and modelling of spectrographs with holographic gratings on freeform surfaces
Eduard R. Muslimov, Marc Ferrari, Emmanuel Hugot +6
In the present paper we demonstrate the approach of using a holographic grating on a freeform surface for advanced spectrographs design. We discuss the surface and groove pattern d…
SNEMO: Improved Empirical Models for Type Ia Supernovae
C. Saunders, G. Aldering, P. Antilogus +39
Type Ia supernova cosmology depends on the ability to fit and standardize observations of supernova magnitudes with an empirical model. We present here a series of new models of Ty…
Curved detectors developments and characterization: application to astronomical instruments
Simona Lombardo, Thibault Behaghel, Bertrand Chambion +8
Many astronomical optical systems have the disadvantage of generating curved focal planes requiring flattening optical elements to project the corrected image on flat detectors. Th…
Design of optical systems with toroidal curved detectors
Eduard Muslimov, Emmanuel Hugot, Marc Ferrari +4
We consider using toroidal curved detectors to improve the performance of imaging optical systems. We demonstrate that some optical systems have an anamorphic field curvature. We c…
Strong Dependence of Type Ia Supernova Standardization on the Local Specific Star Formation Rate
M. Rigault, V. Brinnel, G. Aldering +40
As part of an on-going effort to identify, understand and correct for astrophysics biases in the standardization of Type Ia supernovae (SNIa) for cosmology, we have statistically c…
Spectrographs with holographic gratings on freeform surfaces: design approach and application for the LUVOIR mission
Eduard Muslimov, Marc Ferrari, Emmanuel Hugot +5
In the present paper we demonstrate the approach to use a holographic grating on a freeform surface for advanced spectrographs design. On the example POLLUX spectropolarimeter medi…
