Autor: Ugwoke, R. E., Ubachukwu, A. A., Urama, J. O., Okike, O., Alhassan, J. A., Chukwude, A. E.

Publikováno v: Research in Astronomy and Astrophysics, 23:035017 (15pp), 2023 March

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 a useful tool for this study. A subroutine program written and impleme

Analysis of ground level enhancement events of 29 September 1989; 15 April 2001 and 20 January 2005

Autor: Ugwoke, Romanius Ejike, Ubachukwu, Augustine, Urama, Johnson Ozoemena, Okike, Ogbonnaya, Alhassan, Jibrin Adejoh, Chukwude, Augustine Ejikeme

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 examination of hourly raw CR counts of an array of neutron monitors (NMs) sprea

Multi-Frequency Study of Spectral Indices of BL Lacertae Objects and Flat Spectrum Radio Quasars

Autor: Iyida, E. U., Odo, F. C., Chukwude, A. E., Ubachukwu, A. A.

We present statistical analyses of a large homogenous data sample of Fermi-detected blazars thoroughly studied in order to reassess the relationship between flat-spectrum radio quasars (FSRQs) and subclasses of BL Lacertae objects (BL Lacs) blazar po

Spectral Properties of Fermi Blazars and their Unification Schemes

Autor: Iyida, E. U., Odo, F. C., Chukwude, A. E., Ubachukwu, A. A.

We use the distributions of spectral indices of a large homogenous sample of Fermi-detected blazars to re-investigate the relationship between flat spectrum radio quasars (FSRQs) and subclasses of BL Lac objects (BL Lacs). We compute the broadband sy

Bowshocks in a newly discovered maser source in IRAS 20231+3440

Autor: Ogbodo, Chikaedu, Burns, Ross, Handa, Toshihiro, Nagayama, Takumi, Chibueze, James, Omodaka, Toshihiro, Honma, Mareki, Nakagawa, Akiharu, Ubachukwu, Augustine, Eze, Romanus

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 water maser source in the region of IRAS 20231+3440 as $\pi=0.611\pm0
