  • Gamma-ray fluxes from the c... Gamma-ray fluxes from the core emission of Centaurus A: a puzzle solved
    Fraija, Nissim Monthly Notices of the Royal Astronomical Society, 06/2014, Letnik: 441, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    A high-energy component in the radio galaxy Centaurus A was reported after analysing four years of Fermi data. The spectrum of this component is described by means of a broken power law with a break ...

  • Accounting for Selection Bi... Accounting for Selection Bias and Redshift Evolution in GRB Radio Afterglow Data
    Dainotti, Maria; Levine, Delina; Fraija, Nissim ... Galaxies, 12/2021, Letnik: 9, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    Gamma-ray Bursts (GRBs) are highly energetic events that can be observed at extremely high redshift. However, inherent bias in GRB data due to selection effects and redshift evolution can ...

  • Reducing the Uncertainty on... Reducing the Uncertainty on the Hubble Constant up to 35% with an Improved Statistical Analysis: Different Best-fit Likelihoods for Type Ia Supernovae, Baryon Acoustic Oscillations, Quasars, and Gamma-Ray Bursts
    Dainotti, Maria Giovanna; Bargiacchi, Giada; Bogdan, Malgorzata ... Astrophysical journal/˜The œAstrophysical journal, 07/2023, Letnik: 951, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract Cosmological models and their parameters are widely debated, especially about whether the current discrepancy between the values of the Hubble constant, H 0 , obtained by Type Ia supernovae ...

  • Closure relations during th... Closure relations during the plateau emission of Swift GRBs and the fundamental plane
    Dainotti, Maria Giovanna; Lenart, Aleksander Ł; Fraija, Nissim ... Publications of the Astronomical Society of Japan, 08/2021, Letnik: 73, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract The Neil Gehrels Swift observatory observes gamma-ray burst (GRB) plateaus in X-rays. We test the reliability of the closure relations through the fireball model when dealing with GRB ...

  • Parameter Inference of a St... Parameter Inference of a State-of-the-Art Physical Afterglow Model for GRB 190114C
    Rinaldi, Enrico; Fraija, Nissim; Dainotti, Maria Giovanna Galaxies, 02/2024, Letnik: 12, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    A state-of-the-art semi-analytic gamma-ray burst (GRB) afterglow model with synchrotron self-Compton (SSC) emission has been applied for the first time for parameter inference using real GRB data. We ...

  • Testing a Lepto-Hadronic Tw... Testing a Lepto-Hadronic Two-Zone Model with Extreme High-Synchrotron Peaked BL Lacs and Track-like High-Energy Neutrinos
    Aguilar-Ruiz, Edilberto; Galván-Gámez, Antonio; Fraija, Nissim Galaxies, 12/2023, Letnik: 11, Številka: 6
    Journal Article
    Recenzirano
    Odprti dostop

    Numerous studies suggest that high-energy (HE) neutrinos and ultra-high-energy (UHE) cosmic rays could originate from extremely high-synchrotron peaked (EHSP) BL Lacs, which have been identified as ...

  • The Closure Relations in Hi... The Closure Relations in High-Energy Gamma-ray Bursts Detected by Fermi-LAT
    Dainotti, Maria; Levine, Delina; Fraija, Nissim ... Galaxies, 02/2023, Letnik: 11, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Gamma-ray bursts (GRBs) are brief, intense pulses of high-energy emission associated with extreme astrophysical phenomena, e.g. the death of massive stars or the coalescence of compact objects. They ...

    Journal Article
    Recenzirano
    Odprti dostop

    Long gamma-ray bursts have been widely associated with collapsing massive stars in the framework of collapsar model. High-energy neutrinos and photons can be produced in the internal shocks of middle ...

    Fraija, Nissim Monthly notices of the Royal Astronomical Society, 07/2015, Letnik: 450, Številka: 3
    Journal Article
    Recenzirano

    High-energy neutrinos generated in collimated jets inside the progenitors of gamma-ray bursts (GRBs) have been related to the events detected by IceCube. These neutrinos, produced by hadronic ...
