Reviews

  • Conrado Albertus et al. ( Including Rafid H. Dejrah)
    WISPedia -– the WISPs Encyclopedia
    arrXiv: 2602.09089

    Primarily contributed for sections detailing inflationary paradigms and spin-0 scalar extensions. Played a central role in the manuscript’s development, conducting an extensive literature review to ensure comprehensive coverage of theoretical models, and actively participated in the drafting and editorial refinement of the full encyclopedia.


  • Rafid H. Dejrah
    Multifield Inflation and the Dialogues of Early-Universe Scalars: A Conceptual Review
    Preprints: 202507.0917

  • Rafid H. Dejrah
    f(R) Gravity: Gravitational Waves Tests
    arXiv: 2502.17519

White papers

  • † Eleonora Di Valentino et al. ( Including Rafid H. Dejrah)
    The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
    Phys.Dark Univ., 2212-6864, 2025 / arXiv: 2504.01669

    Contributed by writing the original draft, developing methodologies, and conducting formal analysis to address the Hubble constant (\(H_0\)) tension using a master sample of Type Ia Supernovae (SNe Ia). I curated high-quality SNe Ia data, investigated systematic uncertainties, created visualizations to communicate findings, and refined the analysis to ensure robust conclusions.
