CHAPTER 4 the centre of our Galaxy by the group led by Genzel at the Max Planck Institute in Garching and by the group led by A. Ghez at UCLA. Indians had been at the forefront of the speckle phenomenon in the 1940s. C.V. Raman, and his student G.N. Ramachandran, made fundamental contributions to the understanding of this phenomenon and, indeed, elucidated and anticipated its potential. Some of their results were rediscovered in the astronomical context nearly forty years later! This area was revisited in the 1980s by some Indian theoretical astronomers, and a couple of very interesting results were obtained. With this background, it is natural that we reenter this field in a major way. This is another area where the interaction between physicists and astronomers would be productive. Not only do we have the necessary expertise in this field, it gives us an opportunity to have access to the very best telescopes in the world. For example, if one could develop and build state of the art Speckle Cameras, then one will be able to participate in international collaborations. 3. Detectors for Astronomy The science returns from major national observing facilities is often determined by the quality of focal plane instruments. Other than the optical components, the most important role is played by the detector itself. Whereas it has been possible to import state-of-the-art optical detectors (large format CCDs), it is becoming more and more difficult for Indian astronomers to procure commercially available near infrared and mid infrared detector arrays. This calls for an immediate attention to safeguard the future of near/mid infrared astronomy in India. A possible beginning can be to embark on a collaborative project with national laboratories and undertake technically challenging projects. Through long-term commitments and efforts, some of the technological bottlenecks faced by such labs may be overcome by fresh insight and manpower invested by the astronomy community.
