Shrinivas R. Kulkarni FRS[1] (born 1956) is an astronomer born in India. He is currently a professor of astronomy and planetary science at California Institute of Technology [2] and the director of Caltech Optical Observatory (COO) at California Institute of Technology who oversees Palomar and Keck among other telescopes[2] The success of his astronomical research is seen by 63 Nature Letters, 7 Science Letters, and total of 479 refereed scientific articles that bear his name by the end of 2015 according to ADS .
Kulkarni is the brother of Sunanda Kulkarni, Sudha Murthy, and Jayshree Deshpande.
Background
Shrinivas R. Kulkarni was born in a small town of Kurundwad on October 4, 1956 in southern Maharashtra and had his early education in Hubballi, Karnataka, India[3] [4]. He obtained his MS in Physics from the Indian Institute of Technology, Delhi in 1978, and his Ph.D. at the University of California, Berkeley 1983[2] and became a faculty at California Institute of Technology in 1987[2]. He is a member of 4 national academies around the globe. He was elected a Fellow of the Royal Society, London, in 2001[1], a member of the United States National Academy of Sciences in 2003[5], a honorary fellow of Indian Academy of Sciences in 2012[6], and a foreign member of the Royal Netherlands Academy of Arts and Sciences on September 12, 2016[7] [8]. He has received many awards including the NSF's Alan T. Waterman Award in 1992[9], Helen B. Warner Prize from the American Astronomical Society in 1991[10], Jansky Prize in 2002[11] and Dan David Prize in 2017[12][13]. He has been the Jury Chair for the Infosys Prize for the discipline of Physical Sciences since 2009 [14]. He has mentored 64 young scholars by the end of 2016 according to his website.
Key Discoveries
Kulkarni is known for making key discoveries that open new sub-fields within astronomy, using wide range of wavelength in observation. ADS shows that his papers cover following fields: (1) HI absorption studies of Milky Way Galaxy, (2) pulsars, millisecond pulsars, and globular cluster pulsars, (3) soft gamma-ray repeaters, (4) gamma-ray bursts, and (5) optical transients. He made significant contributions in these sub-fields of astronomy.
He started off his career as a radio astronomer. He studied Milky Way Galaxy using HI absorption under the guidance of his advisor Carl Heiles, and observed its four arms[15]. The review article he wrote with Heiles became a classic in the field of interstellar medium[16].
He discovered the first millisecond pulsar called PSR B1937+21[17] working with Donald C. Backer while he was a graduate student. In 1986, he found the first optical counterpart of binary pulsars[18], while he was a Millikan Fellow at California Institute of Technology. He was instrumental in discovery of the first globular cluster pulsar in 1987[19] using a supercomputer.
With Dale Frail and scientists such as T. murakami at ISAS (progenitor of JAXA that was led by Yasuo Tanaka at that time) he showed that soft gamma-ray repeaters are neutron stars associated with supernova remnants[20][21]. This discovery eventually led to the understanding that neutron stars with extremely high magnetic field called magnetars are the soft gamma-ray repeaters[22].
Caltech-NRAO team which he led showed in 1997 that gamma-ray bursts came from extra-galactic sources[23], and identified optical counterparts[24]. Their research initiated the detailed studies of the sources of gamma-ray bursts along with the European team led by Jan van Paradijs.
He was also a member of the Caltech team that observed the first unrefutable brown dwarf in 1994 that orbited around a star called Gliese 229[25].
His recent work involved Palomar Transient Factory which has succeeded in identifying new groups of optical transients such as superluminous supernova[26], calcium-rich supernova[27], and Luminous red nova[28][29].
