    How We Can Account for Type Ia Supernova Environment in Cosmological Analysis

    Among the other types of supernovae, Type Ia Supernovae (SNe Ia) have less luminosity dispersion at maximum light and show higher optical luminosities. These properties allow to use them as cosmological distan...

    The Influence of the Peculiar Velocities of SNe Ia in Clusters of Galaxies on the Redshift Measurements

    The most intriguing question of modern astronomy is the question of our Universe formation. The Hubble diagram analysis with Type Ia Supernovae (SNe Ia) is widely used to estimate the cosmological parameters w...

    Light Curves of Type Ia Supernovae

    We have studied the light curves of type Ia supernovae (SNe Ia) and the physical parameters inferred from them. We have constructed both analytical and numerical light curves of SNe Ia. Using an empirical rela...

    Local dark energy in the Sculptor Filament of galaxies

    Two dozens of different mass galaxies observed at distances less than 10 Mpc from the Local Group are organized in the elongated structure known as the Sculptor Filament. We use recent Hubble Space Telescope d...

    “Pure” supernovae and accelerated expansion of the Universe

    A special class of type Ia supernovae that is not subject to ordinary and additional intragalactic gray absorption and chemical evolution has been identified. Analysis of the Hubble diagrams constructed for th...
