Instrumentation of "Solar X-Ray Spectrometer" Low Energy Detector (SLD) - Proposed payload onboard Indian satellite

Vadher, N. M; Shah, A. B; Rajmal, J; Vats, H. O; Deshpande, M. R; Seetha, S; Murthy; Sharma, R. K; Umapathy (Astronomical Society of India, 2000)

It is proposed to fly a high spectral and temporal resolution - "Solar X-Ray Spectrometer (SOXS)" onboard Indian satellite. The SOXS will provide the disk integrated flux in the energy range 2 keV-10 MeV. It is composed ...
On Alfvén wave damping in polar coronal holes

Narain, U; Sharma, R. K; Vekstein, G (Astronomical Society of India, 1997)

We reexamine quantitatively the linear resistive and viscous damping of Alfven waves propagating in solar coronal holes, using recently reported observational data on the plasma density and temperature there as well as ...
Signatures of Light Massive Relics on non-linear structure formation

Banerjee, Arka; Das, Subinoy; Maharana, Anshuman; Sharma, R. K (Oxford University Press on behalf of Royal Astronomical Society, 2022-10)

Cosmologies with Light Massive Relics (LiMRs) as a subdominant component of the dark sector are well-motivated from a particle physics perspective, and can also have implications for the σ8 tension between early and late ...
