International Journal of Astronomy and Astrophysics (IJAA) is an international scientific journal dedicated to the publication and public discussion of high quality original research in all the fields of astrophysics and space sciences and related technology. All the manuscripts must be prepared in English and are sub…

We introduce an ultra high energy combined KAM-Rindler fractal spacetime quantum manifold , which increasingly resembles Einstein’s smooth relativity spacetime, with decreasing energy. That way we derive an effective quantum gravity energy-mass relation and c…

The King Abdul Aziz University (KAU) solar observations of Sunspot on daily passes from 1981 to 2009 are used to investigate the North-South asymmetry variation of the sunspot numbers and its area. We found that the asymmetry dominated to be southern during t…

We present a photometric investigation in the uvby β system of a 20 ° × 20 ° field centered at galactic coordinates (l, b) = (105 ° , 5 ° ). This region contains a relatively isolated structure of numerous HII regions in the direction of some of the OB associ…

The paper is a condensed but accurate account of El Naschie’s theory of Cantorian space-time which was used by him to clarify some major problems in theoretical physics and cosmology. In particular El Naschie’s revision and completion of relativity theory and…

This paper represents model of oscillating universe theory. We try to realize model of both electromagnetic waves and spectrum of elementary particles from the unified point of view. Consideration of problems of the gravitational optics and dark matter is dev…

A metric representing a slowly rotating object with quadrupole moment is obtained using a perturbation method to include rotation into the weak limit of the Erez-Rosen metric. This metric is intended to tackle relativistic astrometry and gravitational lensing…

An advanced conceptual design of a high-bit-rate triple product acousto-optical processor is presented that can be applied in a number of astrophysical problems. We briefly describe the Large Millimeter Telescope as one of the potential observational infrastr…

Experimental data observation of the Saturn rings points to the conjecture that the particles constituting the rings may be superconductive. The main argument for this based on the fact that Saturn has a magnetic field and the temperature in its vicinity is l…

In this paper we investigate the fluctuations of solar activity and their links with climatic parameters in West Africa. We achieve our research by investigating several data plotted using averages. Mean to our results we can assume that active solar is assoc…

Whistler observations during nighttimes made at low latitude Indian ground stations Jammu (geomag. lat., 29 ° 26'N; L = 1.17), Nainital (geomag. lat., 19 ° 1'N; L = 1.16) and Varanasi (geomag. lat., 14 ° 55'N; L = 1.11) are used to deduce electron temperature…

All the manuscripts must be prepared in English and are sub… All articles are open access under a CC BY 4.0 licence, with authors retaining copyright.
Authors submit their manuscript, metadata, and declarations through the portal. There is no submission fee.
The editorial office screens the manuscript for scope, completeness, and formatting before assigning a handling editor.
At least two independent reviewers evaluate the manuscript under single-blind review. Where revisions are required, authors respond point by point.
On acceptance the article processing charge is invoiced and the CC BY 4.0 copyright handover is signed.
The article is copyedited, typeset, and given a DOI, then publishes open access with a permanent link.
Manuscripts must be original and not under consideration elsewhere. Submit in Microsoft Word or LaTeX with figures at 300 dpi minimum. Structure research articles as Abstract, Introduction, Methods, Results, Discussion, and References.
Use the journal's numbered (Vancouver) reference style. Cite sources consecutively in the order they appear, and ensure every reference is complete and retrievable.
