Mapping the Spatial Distribution of Dust Extinction in Ngc959 Using Broadband Visible and Mid-ir Filters
We present a method to estimate and map the two-dimensional distribution of dust extinction in the late-type spiral galaxy NGC959 from the theoretical and observed flux ratio of optical V and mid-IR (MIR) 3.6μm images. Our method is applicable to both young and old stellar populations for a range of metallicities, and is not restricted to lines-of-sight toward star-formation (SF) regions. We ex...
متن کاملBROADBAND MID-INFRARED SOLID-STATE LASERS Broadband Mid-Infrared Lasers
A survey of broadband Co2+and Cr2+-based lasers is presented. These mid-IR sources, operating in the very interesting “molecular fingerprint” region between ∼1.6 and 3.5μm offer the broadest bandwidth from all solid-state vibronic lasers. The emphasize is made on Cr2+-doped lasers, which have not only the widest and the highest gain, but also operate at room-temperature and produce the shortest...
متن کاملEnvironmental Investigation and Spatial Distribution of Heavy Metals in the Street Dust of Ahvaz City
Dusts contain heavy metals such as Pb, Zn, Cu, Cr, Cd and As that can threat humanchr('39')s health and environment. Therefore, the spatial distribution of heavy metals concentration and soil pollution monitoring and environmental quality protection seem to be essential. To assess heavy metals pollution level in Ahvaz street dust, 115 street dust samples were collected from main pedestrians. Th...
متن کامل0 High Spatial Resolution Imaging of NGC 1068 in the Mid Infrared
Mid-infrared observations of the central source of NGC 1068 have been obtained with a spatial resolution in the deconvolved image of 0.1 ′′ (∼7 pc). The central source is extended by ∼1 ′′ in the north-south direction but appears un-resolved in the east-west direction over most of its length. About two-thirds of its flux can be ascribed to a core structure which is itself elongated north-south ...
متن کاملThe mineral composition and spatial distribution of the dust ejecta of NGC 6302 ⋆ ⋆ ⋆
We have analysed the full ISO spectrum of the planetary nebula NGC 6302 in order to derive the mineralogical composition of the dust in the nebula. We use an optically thin dust model in combination with laboratory measurements of cosmic dust analogues. We find two main temperature components at about 100 and 50 K respectively, with distinctly different dust compositions. The warm component con...
