Pulsars are highly magnetized rotating dead remnant of a massive star (neutron star). Neutron stars are formed when a massive star runs out of fuel and collapses. The very central region of the star – the core – collapses, crushing together every proton and electron into a neutron. If the core of the collapsing star is between about 1 and 3 solar masses, these newly-created neutrons can stop the collapse, leaving behind a neutron star.
Superenova is a powerful and luminous stellar explosion. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor, either collapses to a neutron star or black hole, or it is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy, before fading over several weeks or months.
Fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond to a few milliseconds, caused by some high-energy astrophysical process not yet understood. While extremely energetic at their source, the strength of the signal reaching Earth has been described as 1,000 times less than from a mobile phone on the Moon.
Basic Space Science Education is the field concerned with sharing the knowledge of astronomy and space science and process with individuals not traditionally considered part of the scientific community. The learners may be children, college students, or adults within the general public. I am interested in propgating this among young Africans especially females among them from countries where there is little or no access to proper scientific education.
My name is Adaeze Ibik, a graduate student of the David A. Dunlap Department of Astronomy and Astrophysics, University of Toronto, Canada.
I am passionate about astronomy education and research especially in Africa. I am working on very bright explosions in the universe called supernovae. A supernova is the explosion that accompanies the death of a star leading to different remnants depending on the star mass. A class of supernova exists that seems to explode into some material, located close to the star.
There can be several solar masses worth of material, which are thought to be released as a result of mass loss episodes by the parent star slightly before the explosion. Because of the interaction of the supernova shock, these materials cause the supernova to be very bright. The nature of the parent star and the mechanism by which they expel such large quantities of mass prior to explosions are largely unknown. Hence, I am using radio observations of samples of supernovae, obtained years after the explosion, to study the distribution of the material as a means to understand their power source.
I am also interested in neutron stars, fast radio bursts and radio astronomy generally.
One of the keys of great people is their disloyalty to any information that does not produce results.

A human being is a part of the whole – called by us Universe – a part limited in time and space. We experience our thoughts and feelings as something separated from the rest – a kind of optical delusion of our consciousness. This delusion is a kind of prison for us, restricting us to our personal desires, and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.
— Albert Einstein
