Peer-Reviewed and Preprints

  • N. Bostan, R. H. Dejrah, C. Dioguardi, and A. Racioppi
    Natural inflation in Palatini F(R, X)
    JCAP, 1475-7516, 2025 / arXiv: 2503.16324
    Contributed equally to this work as the other authors.

  • † Maria Giovanna Dainotti et al. ( Including Rafid H. Dejrah)
    A New Master Supernovae Ia sample and the investigation of the H0 tension
    JHEAp, 2214-4048, 2025 / arXiv: 2501.11772

    I contributed by writing the original draft, developing the methodology, and conducting formal analysis. I also performed data curation to ensure the integrity and quality of the supernovae dataset, carried out detailed investigations to probe the Hubble constant tension, and created visualizations to effectively communicate our findings.

  • Nilay Bostan and Rafid H. Dejrah
    Inflationary dynamics and observables: β-exponential models in Palatini R2 gravity
    Nuclear Physics B, 0550-3213, 2025 / arXiv: 2409.10398
    Contributed equally to this work as the other authors.

Reviews

  • 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


    I 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.
