On the decrease of sunspot activity and absence of severe space weather conditions during the multiple planetary conjunction periods of 1850-2000 AD
N. G. Nisha, T. E. Girish
We have studied solar activity and space weather conditions during multiple planetary conjunction periods ( MPC) as observed from Earth during the years 1850-2000 AD. Significant d…
X-ray Reflectivity measurements of Speculum metal mirrors using Synchrotron radiation
E. A Nazimudeen, T. E Girish, Sunila Abraham +5
Recent advances in grazing incidence X-ray optics using synchrotron radiation sources have stimulated the need for basic research in high quality mirror materials for novel applica…
Early Compton Effect experiments revisited: Evidence for outstanding hard X-ray reflectivity of speculum metal
Nazimudeen E. A, T. E. Girish, Sunila Abraham
Experiments related to X-ray optics carried out by A. H. Compton and his collaborators during 1923-1927, led to the Nobel Prize winning discovery of Compton Effect. Based on the cr…
History of solar wind and space plasma physics revisited
T. E. Girish, G. Gopkumar, P. E. Eapen
A paper published by Scottish geophysicist J.A. Broun in 1858 contained several pioneering and remarkable ideas in solar-terrestrial physics. He could anticipate more or less corre…
Parity of the Solar Magnetic Fields and Related Astrophysical Phenomena
G. Gopkumar, T. E. Girish
The cumulative contribution of odd (Bo) and even (BE) parity zonal magnetic multipoles to the solar magnetic fields is calculated using spherical harmonic coefficients of the photo…
A possible relationship between Global Warming and Lightning Activity in India during the period 1998-2009
Felix Pereira B., Priyadarsini G., T. E. Girish
Lightning activity on a global scale has been studied season wise using satellite data for the period from 1998 to 2009. Lightning activity shows an increasing trend during the per…
