The newly formed High Energy Astrophysics (HEA) Group at the Sharjah Academy of Astronomy, Space Science, and Technology (SAASST) and the University of Sharjah (UoS) focuses on the accretion processes onto compact objects, mainly on neutron stars and black holes, across the electromagnetic spectrum. Our research lies on observations of Galactic black holes as well as accreting neutron stars in both high and low mass X-ray binary systems. An extensive research programme on accreting compact objects utilizes an armada of X-ray observsatories (e.g., XMM-Newton/ESA, Chandra/NASA, INTEGRAL/ESA, Neil Gehrels Swift Observatory/NASA, NuStar/NASA, etc) alongside major ground-based facilities such as the European's Southen Observatory (ESO), Very Large Telescope (VLT) and smaller 1m-class telescopes. Besides the observational part, in our research group we are using an advanced inventory of state-of-the-art tools such as (magneto)hydrodynamical and General-Relativistic (magneto)hydrodynamical simulations, alongside radiative transfer and ray-tracing tools to further study and shed light onto the elusive nature of these accreting compact objects and their surrounding environment. Moreover, this group will provide a direct science exploitation of the forthcoming 3U CubeSat SHARJAHSAT-1. The primary science payload on board is the iXRD (developed by Sabanci University) which will provide an improved version of XRD on board BeEagleSat. The leading technology behind iXRD is a CdZnTe-based crystal, operational in the hard X-rays regime, between 20 and 200 keV energy range. The target spectral resolution of the detector is 6 keV at 60 keV. Its' main science goal of the mission is long term monitoring of the brightest galactic X-ray sources, transient and persistent. Black holes and pulsars can emit radiation up to a few 100 keVs making them ideal targets. In addition, hard X-ray spectra from solar flare and coronal holes will be studied. Transient bright events, such as gamma-ray burst (GRB) and magnetar bursts will be studied as well as target of opportunities (TOO). Currently the project is at the Critical Design Review (CDR) level and the anticipated launch is planned for early-to-mid 2021.
