  • Forty Years of X-Ray Binaries 

    van den Heuvel, E.P.J. (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray ...

  • A Decision between Bayesian and Frequentist Upper Limit in Analyzing Continuous Gravitational Waves 

    Gholami, Iraj (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    Given the sensitivity of current ground-based Gravitational Wave (GW) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. Hence, any data analysis of detector ...

  • The Role of Thermal Conduction in Accretion Disks with Outflows 

    Ghanbari, Jamshid؛ Tajmohammadi, Arezoo (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in ...

  • Solar Mini-Dimming Kinematics and Their Positive Correlations with Coronal Mass Ejections and Prominence 

    Alipour, Nasibe؛ Safari, Hossein (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special ...

  • Geomagnetic Field E ect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles 

    Khakian Ghomi, Mehdi؛ Fazlalizadeh, Maedeh؛ Bahmanabadi, Mahmoud؛ Hedayati Kh, Hadi (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth ...

  • Evaluation of New MOND Interpolating Function with Rotation Curves of Galaxies 

    Haghi, Hosein؛ Ghasemi, Hamed؛ Zhao, HongSheng (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and ...

  • Stellar Populations in the Central Galaxies of Fossil Groups 

    G. Khosroshahi, Habib؛ A. Nolan, Louisa (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2014-06-01)
    It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium ...
