Richard Strom was born and raised in New York City. He gained entrance to the selective Bronx High School of Science, and pursued studies at Tufts University in Medford, Massachusetts, where he earned a B.A. in physics. Switching to radio astronomy, he obtained M.Sc. and Ph.D. degrees from the University of Manchester (Jodrell Bank) in 1969 and 1972, followed by postdoctoral research at Leiden Observatory. Since 1975 he has been a research astronomer at Dwingeloo Radio Observatory, and adjunct professor at the University of Amsterdam (1996). He has also been adjunct or visiting professor in Singapore, Australia and China, and was elected a fellow of the Institute of Physics, Singapore. He does research in many areas of radio astronomy (supernova remnants, giant radio galaxies, gamma-ray bursts, pulsars, Jupiter, cosmic rays) including its history. He is also interested in Chinese astronomical records, and has held a CAS Visiting Professorship for Senior International Scientists for periods of up to 4 months during the past 3 years.
摘 要：In less than a decade, Gamma-Ray Bursts (GRBs) have been transformed from an obscure, seemingly insoluble riddle to a hot item of 21st Century astrophysics. In a way this is astonishing: for over a quarter of a century there was practically no progress in the discipline, and what was regarded by many as the probable nature of GRBs ultimately proved to be way off the mark. But as with other similar dilemmas (detection of exoplanets being one recent example), after the first few successes the required techniques were refined and honed until detection and follow-up became, if not routine, then at least governed by certain patterns of expectation. (It should be noted that a significant fraction of GRBs, the short bursts [t < 2 s], may be a different phenomenon.) I will examine the progress which has been made in detecting and studying radio (where most of my own modest contribution has been) and optical transients. Looking to the past, I will present my thoughts on searching ancient Chinese records for bright naked-eye transients, and discuss some candidates. I will also suggest in which direction(s) future transient surveys might go, and discuss some of the possible roles for planned new instruments, especially future facilities in China.
