An atmospheric researcher whose joint 2001 study examined changes in Earth’s emitted infrared spectrum. The work uses the spectral signatures of atmospheric gases to investigate a changing greenhouse effect. It illustrates why retaining wavelength information can reveal physical processes hidden by a single broadband radiation measurement.^[ref]

A researcher whose team compared satellite infrared spectra separated by twenty-seven years. The study links changes in outgoing longwave radiation to the wavelength-dependent absorption by each greenhouse gas, making the atmosphere’s changing radiative behavior an observable spectral signal.^[ref]

An atmospheric researcher whose joint work with John E. Harries and colleagues used infrared spectra to investigate the greenhouse effect. Comparing radiation escaping to space at different wavelengths distinguishes the influence of atmospheric gases from a simple change in total emitted power.^[ref]

An atmospheric physicist whose team compared satellite measurements of outgoing longwave radiation from 1970 and 1997. Differences in the infrared spectra carry the signatures of changing atmospheric absorbers. The comparison supplies observational evidence about the changing greenhouse effect, rather than relying only on a surface-temperature record.^[ref]

An astrophysicist whose research uses absorption features in distant quasar spectra to probe intervening gas. High-resolution measurements constrain physical conditions in early galaxies and can test whether fundamental constants changed over cosmic time. His work also uses atomic fine-structure lines to investigate the evolution of the cosmic microwave background temperature.^[ref]

An astronomical-instrumentation researcher involved in precision optical fabrication at LAM. The laboratory’s account of the Roman telescope project identifies him with the development and delivery of off-axis mirrors for a coronagraph. Controlled stressing during polishing helps create accurate aspheric surfaces, connecting mechanical deformation and optical metrology with the suppression of unwanted starlight.^[ref]

An astronomical-optics researcher whose active optics methods use controlled elastic deformation to produce accurate optical surfaces. A mirror can be polished while stressed and then released into a desired aspheric shape; related methods change curvature during use. His work connects elasticity calculations with telescope and spectrograph construction, reducing fabrication errors while keeping optical designs relatively simple.^[ref]
