Anish Roshi, National Radio Astronomy Observatory

The Green Bank Telescope (GBT) is the world’s premiere single-dish radio telescope operating at metre to millimetre wavelengths. Its enormous 100-metre-diameter collecting area, unblocked aperture and excellent surface accuracy provide unprecedented sensitivity across the telescope’s full 0.1 – 116 GHz operating range.

To keep up the discovery potential of the GBT, the observatory, in collaboration with college and university groups, has a vigorous development program. This program takes advantage of the latest technology and provides the user community with a constantly improving facility. In this talk, Roshi will highlight the current capabilities of the GBT and discuss two new instrument development projects: the Versatile GBT Astronomical Spectrometer (VEGAS), and the Focal L-band Array for the GBT (FLAG).

D. Anish Roshi is currently a staff scientist at NRAO Charlottesville and Green Bank. He did his doctorate from the National Centre for Radio Astrophysics, Tata Institute of Fundamental Research (TIFR), Pune, India. Since then, he has worked as a member of the faculty at TIFR, Pune and Raman Research Institute, Bangalore, India. His primary interests are galactic interstellar medium and star formation. He has also been actively involved in radio astronomy instrumentation work. Currently, he is part of the Phased Array Feed and Spectrometer development projects at NRAO.
