A complete Raman mapping of phase transitions in Si under indentation (2008)
Das, C. R., Hsu, H. C., Dhara, S., Bhaduri, A. K., Raj, B., Chen, L. C., ...
Crystalline Si substrates are studied for pressure induced phase transformation under indentation at room temperature using Berkovich tip. Raman scattering study is used for the identification of the...
Evolution of morphology of undercooled droplets in Cu-Cu3p near euteictic alloy (2005)
Ray, A, Bhattacharya, V, Chattopadhyay, K
The paper reports results of an investigation on phase evolution from undercooled Cu-Cu3P eutectic liquid entrained in a copper matrix. The results indicate attainment of large undercooling of the...
Detection of a radio counterpart to the 27 December 2004 giant flare from SGR 1806-20 (2005)
Cameron, PB, Chandra, P, Ray, A, Kulkarni, SR, Frail, DA, Wieringa, MH, ...
It was established over a decade ago that the remarkable high-energy transients known as soft $\gamma$-ray repeaters (SGRs) are located in our Galaxy and originate from neutron stars with intense...

Participation in the RACS sentinel node biopsy versus axillary clearance trial (2005)
Wetzig, NR, Gill, PG, Ung, O, Collins, J, Kollias, J, Gillett, D, ...
Background: The Royal Australasian College of Surgeons (RACS) SNAC trial is a randomized controlled trial of sentinel node biopsy (SNB) versus axillary clearance (AC). It opened in May 2001 and is...
The Late-Time Radio Emission from SN 1993J at Meter Wavelengths (2004)
Chandra, P, Ray, A, Bhatnagar, S
This paper presents the investigations of SN 1993J using low-frequency observations with the Giant Metrewave Radio Telescope (GMRT). We analyze the light curves of SN 1993J at 1420, 610, 325, and 243...
X-ray and radio prompt emission from a hypernova SN 2002ap (2004)
Chandra, P, Ray, A, Sutaria, F
Here we report on combined X-ray and radio observations of SN 2002ap with XMM-Newton ToO observation and GMRT observations aided with VLA published results. In deriving the X-ray flux of SN 2002ap we...

Low frequency radio and X-ray properties of core-collapse supernovae (2003)
Ray, A, Chandra, P, Sutaria, F, Bhatnagar, S
Radio and X-ray studies of young supernovae probe the interaction between the supernova shock waves and the surrounding medium and give clues to the nature and past of the progenitor star. Here we...
Low frequency observations of SN 1993J with Giant Meterwave Radio Telescope (2003)
Chandra, P, Ray, A, Bhatnagar, S
In this paper, we discuss the low frequency spectrum of SN 1993J with GMRT. We observed SN 1993J at several epochs in 20cm, 50cm, 90cm and 125cm wavelengths and achieved near simultaneous spectra. We...
The nature of the prompt X-ray and radio emission from SN2002ap (2002)
Sutaria, FK, Chandra, P, Bhatnagar, S, Ray, A
We report on the combined X-ray and radio observations of the type Ic SN 2002ap, using XMM-Newton ToO observation of M74 and the Giant Metrewave Radio Telescope (GMRT). We account for the presence of...
