Explaining the photometric and spectroscopic properties of The Sip-39 galaxy pair

Autor: Haydar R. Al-baqir, Abdullah K. Ahmed

Publikováno v: Baghdad Science Journal, Vol 21, Iss 4 (2024)

The Sip-39 pair’s galaxies have been investigated using photometric and spectroscopic methods; the observation data was collected from the SDSS's Data Release (DR17) and fitted to ellipses through utilizing the Image Reduction and Analysis Facility

Crystallization and melting behavior of i-PP: a perspective from Flory's thermodynamic equilibrium theory and DSC experiment

Autor: Mamdouh A. Al-Harthi, Abdullah K. Ahmed, Muhammad Atiqullah, Dev R. Pradhan

Publikováno v: RSC Advances. 7:42491-42504

Crystallization and melting are integral parts of the isotactic polypropylene (i-PP) end-product fabrication process. Therefore, the nonisothermal crystallization kinetics and melting behavior of an un-nucleated commercial i-PP have been pursued by i

Surface Photometry of Spiral Galaxy NGC 5005 and Elliptical Galaxy NGC 4278

Autor: Zahraa Adnan, Abdullah K. Ahmed

Publikováno v: Baghdad Science Journal (2018)

Two galaxies have been chosen, spiral galaxy NGC 5005 and elliptical galaxy NGC 4278 to study their photometric properties by using surface photometric techniques with griz-Filters. Observations are obtained from the Sloan Digital Sky Survey (SDSS).
