Principal Component Analysis of Ground Level Enhancement of Cosmic Ray Events
R. E. Ugwoke, A. A. Ubachukwu, J. O. Urama +3
We applied principal component analysis (PCA) to the study of five ground level enhancement (GLE) of cosmic ray (CR) events. The nature of the multivariate data involved makes PCA…
Analysis of ground level enhancement events of 29 September 1989; 15 April 2001 and 20 January 2005
Romanius Ejike Ugwoke, Augustine Ubachukwu, Johnson Ozoemena Urama +3
We present the results of analyses of the ground level enhancements (GLEs) of cosmic ray (CR) events of 29 September 1989; 15 April 2001 and 20 January 2005. This involve examinati…
Bowshocks in a newly discovered maser source in IRAS 20231+3440
Chikaedu Ogbodo, Ross Burns, Toshihiro Handa +7
From measuring the annual parallax of water masers over one and a half years with VERA, we present the trigonometric parallax and corresponding distance of another newly identified…
On the Lorentz Factor of Superluminal Sources
Chika Christian Onuchukwu, Augustine Anyaegbunam Ubachukwu
We investigate the properties of features seen within superluminal sources often referred to as components. Our result indicates a fairly strong correlation of r=0.6 for quasars, r…
