The Chicago Bears came out with a 31-27 victory over the Green Bay Packers in what was yet another fourth-quarter comeback by quarterback Caleb Williams and company. Williams made history with the ...

What a game the Bears-Packers wild-card thriller was. Chicago came back from a 21–6 deficit to eventually win 31–27 as the game came down to the final seconds. It was the Bears’ first playoff win in ...

WE have recently obtained a series of spectra of the night sky in the wave-length region 1–2 µ. A lead sulphide cell was used as the detector in a grating spectrograph normally used for photographic ...

The Carnegie Planet Finder Spectrograph (PFS) has been constructed for use with the Magellan telescopes at Las Campanas Observatory in Chile. PFS has been optimized for high-precision measurement of ...

The Carnegie Planet Finder Spectrograph is being constructed for use at the Magellan Telescopes at Las Campanas Observatory in Chile. Its primary scientific objective is the detection of extrasolar ...

The COMICS spectrograph consists of 5 arrays, each 320 pixels in the dispersion direction, separated by the equivalent of 250 pixels. The entire spectrum fits on a single array in low-resolution mode, ...

The Echelle spectrograph enables us to obtain high-resolution spectra by a comparatively wide entrance slit using the higher orders of an echelle grating. Because of the high order numbers, light from ...

THE USE OF A PLANE GRATING IN STELLAR SPECTRO-SCOPY.—In No. 5, vol. vi., of the Journal of the Royal Astronomical Society (Canada) there is an interesting note describing some preliminary tests, made ...

Abstract: We demonstrated liquid metal based optical components such as mirrors and reflection gratings for building on-chip optofluidic spectrographs and monochromators. We designed a Czerny-Turner ...

A brand new spectrograph on the Gemini North telescope has seen first light, detecting elements in a dying star known as the Jewel Bug Nebula. When you purchase through links on our site, we may earn ...
