ADJUNCT ASSOCIATE PROFESSOR, RESEARCH SCIENTIST III, CSPAR

Biography

Dr. Narayana Bhat was born in India and did his undergraduate degree at the Mysore University (Physics and Mathematics). After completing a year in the Training School at the Bhabha Atomic Research Centre in Mumbai he joined the Tata Institute of Fundamental Research in Mumbai. His Ph.D. focused on the study of low energy muons underground and the search for massive unstable particles in cosmic rays using experiments in the Kolar Gold Fields where the first cosmic ray neutrino was detected. After completing his PhD from the then University of Bombay his post-doctoral work was carried out at the University of Durham (UK) during 1979-82 where he participated in the Gamma-ray line Astronomy studies using balloon borne shielded HPGe detectors.

He continued his work at the Tata Institute on Very High Energy Gamma-ray Astronomy using ground based atmospheric Cerenkov technique at the High-Altitude Cosmic Ray Laboratory at Ootacamund. Here he also worked on High Energy Cosmic Ray Physics experiments like the search for Tachyons in cosmic rays, search for GeV energy Gamma-rays from GRBs, search for Gamma-rays from the exploding primordial black holes etc. In 1985, he developed the first instrumentation for using the Charge Coupled Devices (CCD) in Optical Astronomy in India. He also worked on Galaxy Photometry using the 2.2m Vainu Bappu Telescope, located near Bangalore. He joined the Burst and Transient Source Experiment (BATSE, onboard the Compton Gamma-ray Observatory) team in 1991 at the George Marshall Space Flight Center in Huntsville as a NASA Senior NRC Fellow where he worked until 1993.

After returning to Tata Institute he started a Very High Energy Gamma-ray Astronomy Observatory (HEGRO) at Pachmarhi (Central India) where the wavefront sampling technique was developed. He was responsible for developing a new advanced CAMAC based fast digital data recording system. He was also responsible for the new Very High Energy Gamma-ray Astronomy Observatory (HAGAR) at Hanle at an altitude of 14,500' on the foothills of Himalayas. After taking voluntary retirement from the Tata Institute where he was a Senior Professor, he joined the Gamma-ray Burst Monitor Team in 2003. His main research interests are High Energy Astronomy and Astrophysics, data analysis, detector development, and instrumentation. Currently Dr. Bhat is working on the analyses of data from the Advanced Neutron Spectrometer onboard the International Space Station.

Dr. Bhat is also an Adjunct Professor at the Space Science Department of the University of Alabama in Huntsville.
