Full Characterisation of the Polarisation Primary Beam of the GRAO 32-m Telescope
Theophilus Ansah-Narh, Nia Imara, Benedicta Woode +4
Direction-dependent instrumental polarisation is a major systematic limitation in high-fidelity single-dish radio polarimetry, yet a unified characterisation of beam leakage and th…
The Ghana Radio Astronomy Observatory
Emmanuel Proven-Adzri, Nia Imara, Theophilus Ansah-Narh +7
The Ghana Radio Astronomy Observatory (GRAO) marks a pivotal advance in African radio astronomy through the successful transformation of a decommissioned 32 m satellite communicati…
Pulsar glitch activities: the spin parameters approach
Innocent Okwudili Eya, Evaristus Uzochukwu Iyida
Glitch activity refers to the mean increase in pulsar spin frequency per year due to rotational glitches. It is an important tool for studying super-nuclear matter using neutron st…
On the pulsar spin frequency derivatives and the glitch activity
Innocent O. Eya, Jibrin A. Alhassan, Evaristus U. Iyida +2
The number of sudden spin-ups in radio pulsars known as pulsar glitches has increased over the years. Though a consensus has not been reached with regards to the actual cause of th…
Radio Core-Dominance of Fermi-Blazars: Implication for Blazar Unification
E. U. Iyida, F. C. Odo, A. E. Chukwude
...The distribution of radio core-dominance is consistent with average projection angles of 13.5, 14.8, 16.8, 20.4, and 28.2 for ISPs, LSPs, FSRQs, HSPs, and radio galaxies, respec…
On the challenges of Angular Momentum Transfer Mechanism of Pulsar Glitches
I. O. Eya, C. I. Eze, E. U. Iyida
The angular momentum transfer mechanism of pulsar glitches for over four decades now stands as standalone theory with regards to glitch sizes and inter-glitch time intervals. Howev…
Spectral Properties of Fermi Blazars and their Unification Schemes
E. U. Iyida, F. C. Odo, A. E. Chukwude +1
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) a…
On the bimodal nature of the distributions of pulsar glitch sizes
I. O. Eya, E. U. Iyida, C. I. Eze
Pulsar glitches are sudden spin-ups in pulsar spin frequency (). The glitch size, , is a key parameter in any mechanism puts across towards the understanding of the events…
Microglitches in radio pulsars: the role of strange nuggets
Innocent Okwudili Eya, Evaristus Uzochukwu Iyida, Johnson Ozoemene +2
Strange Nuggets are believed to be among the relics of the early universe. They appear as dark matter due to their low charge-to-mass ratio. Their distribution is believed to be th…
