Kumar, Jayshreekar Pant Abstract Type : Oral Abstract Category : Instrumentation and Techniques Abstract : The faint object spectrograph and camera (FOSC) designed and developed for the 3.6-m Devasthal optical telescope (DOT) can have several modes of science observations. It has been used for some science observations on DOT and the performance is found to be satisfactory and as per the expectations. It is primarily designed for deep spectroscopy and imaging studies of faint celestial objects. The new observing modes presently being implemented in FOSC are (i) fast multi-color imaging/spectroscopy using a frame-transfer camera, (ii) seeing measurements using a DIMM-type setup and a wedge prism at the pupil plane, (iii) polarimetry and spectro-polarimetry mode, (iv) autonomous monitoring of sky parameters along with science observations. The status update of instrumentation and upgradation activities on FOSC will be presented. The images and spectra obtained using FOSC on DOT will also be presented. |
