An atlas of Hubble Space Telescope spectra and images of nearby spiral galaxies
Hughes, M.A.; Alonso-Herrero, A.; Axon, D.J.; Scarlata, C.; Atkinson, J.; Batcheldor, D.; Binney, J.; Capetti, A.; Carollo, C.M.; Dressel, L.; Gerssen, J.; Macchetto, F.D.; Maciejewski, W.; Marconi, A.; Merrifield, M.; Ruiz, M.; Sparks, W.; Stiavelli, M.; Tsvetanov, Z.; van der Marel, R. (2003)We have observed 54 nearby spiral galaxies with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope to obtain optical long-slit spectra of nuclear gas disks and STIS optical ( R band) images of ... -
Circular polarization in scattered light as a possible biomarker
Sparks, W.; Hough, J.; Kolokolova, L.; Germer, T.A.; Chen, F.; DasSarma, S.; DasSarma, P.; Robb, F.T.; Manset, N.; Reid, I.; Macchetto, F.D.; Martin, W. (2009)Biological molecules exhibit homochirality and are optically active. Therefore, it is possible that the scattering of light by biological molecules might result in a macroscopic signature in the form of circular polarization. ... -
Correction for Sparks et al., Detection of circular polarization in light scattered from photosynthetic microbes [fig 1]
Sparks, W.B.; Hough, J.; Germer, T.A.; Chen, F.; DasSarma, S.; DasSarma, P.; Robb, F.T.; Manset, N.; Kolokolova, L.; Reid, N.; Macchetto, F.D.; Martin, William Eugene (2009-06-30) -
Detection of circular polarization in light scattered from photosynthetic microbes
Sparks, W.; Hough, J.; Germer, T.A.; Chen, F.; DasSarma, S.; DasSarma, P.; Robb, F.T.; Manset, N.; Kolokolova, L.; Reid, N.; Macchetto, F.D.; Martin, William Eugene (2009-05)The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the universe. A candidate universal biosignature is homochirality, ... -
