Far-infrared photometry of deeply embedded outflow sources
Abstract. We present far-infrared maps and spectroscopy for several deeply embedded protostellar objects from data acquired with the ISO instruments PHOT and LWS. Spectral energy distributions for Cep E, HH 211-MM, IC 1396 W, L 1157, L 1211 and RNO 15 FIR indicate that these are relatively cold Class 0 sources. Several previously undetected deeply embedded sources are found in the vicinity of o...
متن کاملOptical and Infrared Signatures of Ultra-luminous X-ray Sources
We have constructed a model to describe the optical emission from ultra-luminous Xray sources (ULXs). We assume a binary model with a black hole accreting matter from a Roche lobe filling companion star. We consider the effects of radiative transport and radiative equilibrium in the irradiated surfaces of both the star and a thin accretion disk. We have developed this model as a tool with which...
متن کاملRefractive Dual Band Infrared Imager Optical Design
Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...
متن کاملOPTICAL STUDIES OF COLORED CHEMICAL SPECIES
Evanescent wave spectroscopy using thin optically transparent electrodes and multiple reflections allows unique observations of the electrochemical interphase since the region of solution sampled is typically 100 nm from the electrode in the visible spectral region. This technique is found to be highly sensitive to the presence of absorbing adsorbed species
متن کاملSurface-enhanced infrared absorption studies towards a new optical biosensor
Reflectometric interference spectroscopy (RIfS), which is well-established in the visual regime, measures the optical thickness change of a sensitive layer caused, e.g., by binding an analyte. When operated in the mid-infrared range the sensor provides additional information via weak absorption spectra (fingerprints). The originally poor spectra are magnified by surface-enhanced infrared absorp...
