Spectral Structure In Fr II Radio Galaxies And Jets
(University of Chicago Press/ American Astronomical Society, 2001-11)Using spectral tomography to separate overlapping spectral features in a sample of FR II radio galaxies, we Ðnd a variety of spatial/spectral features that are not easily described in the context of current models. In ... -
Spectral surface albedo over Morocco and its impact on radiative forcing of Saharan dust
(2009-02)In May-June 2006, airborne and ground-based solar (0.3-2.2 mu m) and thermal infrared (4-42 mu m) radiation measurements have been performed in Morocco within the Saharan Mineral Dust Experiment (SAMUM). Upwelling and ... -
The spectral–temporal properties of the prompt pulses and rapid decay phase of gamma-ray bursts
(2010)The prompt emission from gamma-ray burst is the brightest electromagnetic emission known, yet its origin is not understood. The flux density of individual prompt pulses of a GRB can be represented by an analytical expression ... -

Spectropolarimetric evidence for a kicked supermassive black hole in the quasar E1821+643
(2010)We report spectropolarimetric observations of the quasar E1821+643 (z = 0.297), which suggest that it may be an example of gravitational recoil due to anisotropic emission of gravitational waves following the merger of a ... -
Spectropolarimetry of the 3-micron ice band in Elias 16 (Taurus Dark Cloud)
(1988)Polarization data between 1.2 and 3.8 μm, including spectropolarimetry in the 3-μm ice feature, are presented for the highly reddened field star Elias 16 in the Taurus Dark Cloud. The polarization is observed to increase ... -
Spectropolarimetry of the 3-micron ice feature in molecular clouds. II : GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud)
(1989)Spectropolarimetric observations in the 3-micron ice band are presented for the infrared sources GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud). Some continuum polarization measurements between 1.2 and 5.0 ... -
Spectropolarimetry of the 3-μm water-ice feature towards young stellar objects
(2002)We present spectropolarimetry of the 3-μm water-ice feature towards five young stellar objects embedded in molecular clouds, including the Becklin–Neugebauer object, with wavelength range and spectral resolution much ... -
Spectropolarimetry of the 3.4 m Band in the Quintuplet
(Astronomical Society of the Pacific, 2005)We present spectropolarimetry of the 3.4?m solid hydrocarbon absorption feature arising in the ISM toward the Quintuplet member GCS3-II, permitting for the first time a comparison of the hydrocarbon and silicate polarizations ... -
Spectropolarimetry of the molecular-hydrogen line emission from OMC-1
(1988)Observations of the H2 v = 1-0 S(1) line at 35 km/s velocity resolution were obtained at several locations within OMC-1, including the molecular hydrogen reflection nebula. All line profiles are smooth and show no evidence ... -
Spectropolarimetry of the ultraluminous infrared galaxy IRAS 110548-1131
(1993)From spectropolarimetric observations of the galaxy IRAS 110548-1131 we report very strong, broad H-alpha emission (FWHM 7600 km/s) in the polarized flux spectrum. This suggests that IRAS 110548-1131 has an obscured ...
