Cosmic ray electron acceleration in the remnant of nova GK Persei?
N. G. Kantharia, G. C. Anupama, Prasad Subramanian
Radio observations of the nova remnant of GK Per around 1985 (epoch 1) have shown it to have a spectral index of -0.4 (S propto nu^alpha) at frequencies <1.4 GHz and a spectral ind…
Relativistic and correlation effects in atoms
B. P. Das, K. V. P. Latha, Bijaya K. Sahoo +3
This review article deals with some case studies of relativistic and correlation effects in atomic systems. After a brief introduction to relativistic many-electron theory, a numbe…
CH stars at High Galactic Latitudes
Aruna Goswami
In the present work we report on several CH stars identified in a sample of Faint High Latitude Carbon stars from Hamburg survey and discuss their medium resolution spectra coverin…
Relativistic unitary coupled cluster theory and applications
Chiranjib Sur, Rajat K Chaudhuri, Bijaya K. Sahoo +2
We present the first formulation and application of relativistic unitary coupled cluster theory to atomic properties. The remarkable features of this theory are highlighted, and it…
Probing neutrino mixing angles with ultrahigh energy neutrino telescopes
Pijushpani Bhattacharjee, Nayantara Gupta
We point out that detecting $\nuebar$'s from distant astrophysical sources with the up-coming and future neutrino telescopes using the Glashow resonance channel $\nuebar e^{-}\to W…
On the method of estimating emission altitude from relativistic phase shift in pulsars
R. T. Gangadhara
The radiation by relativistic plasma particles is beamed in the direction of field line tangents in the corotating frame, but in an inertial frame it is aberrated toward the direct…
