Revealing the unusual structure of the KAT-7-discovered giant radio galaxy J0133− 1302

N Mhlahlo, M Jamrozy - Monthly Notices of the Royal …, 2021 - academic.oup.com
We present a new study of the 1.7 Mpc KAT-7-discovered Giant Radio Galaxy, J0133− 1302,
which was carried out using GMRT data at 323 and 608 MHz. This source is located at RA …

Multi-frequency study of spectral indices of BL Lacertae objects and flat-spectrum radio quasars

EU Iyida, FC Odo, AE Chukwude, AA Ubachukwu - New Astronomy, 2022 - Elsevier
We present statistical analyses of large homogenous data sample of Fermi-detected blazars
thoroughly studied in order to reassess the relationship between flat-spectrum radio quasars …

A possible tension between galaxy rotational velocity and observed physical properties

L Shamir, D McAdam - arXiv preprint arXiv:2212.04044, 2022 - arxiv.org
The discrepancy between the mass of galaxies and their rotational velocity is one of the
most puzzling scientific phenomena. Despite over a century of research, this phenomenon is …

Radio core-dominance of Fermi-blazars: implication for blazar unification

EU Iyida, FC Odo, AE Chukwude - Astrophysics and Space Science, 2021 - Springer
In this paper, we use the distributions of two-component radio emissions to investigate the
consequences of relativistic beaming on the unified scheme of blazar populations and radio …

Spectral properties of Fermi blazars and their unification schemes

EU Iyida, FC Odo, AE Chukwude, AA Ubachukwu - Open Astronomy, 2020 - degruyter.com
We use the distributions of spectral indices (α v) of a large homogenous sample of Fermi-
detected blazars to re-investigate the relationship between flat spectrum radio quasars …
