    Oral

    AS Eridani is a 2.664152 day, semi-detached Algol type binary system. Gamarova, Mkrtichian & Kusakin (2000) discovered a short-period 24 min pulsation in a primary mass-accreting component. The oscillation spectrum has been investigated by Mkrtichian et al. (2004), they suggested that AS Eri is a promising pulsating star for further detailed investigations.
    We started a new campaign of...

  2. 353. High redshift Quasars selection with deep Optical & Near-IR photometry and Photo-z technique for EoR study

    Oral

    We present the technique for selecting high redshift quasar candidates, $z \approx 6 – 11$, suitable for studying the Epoch of Reionization (EoR). Such technique is important for deep and resource-intensive spectroscopic follow-up to confirm the final identification of the sources as well as studying the Inter Galactic Medium (IGM) and its environment. We employ deep optical and near-infrared...

  3. 377. Squeezed bispectrum for multi-fields inflationaly model with constant metric in field space

    Oral

    We study non-Gaussianities in primordial perturbations by using the Delta-N approach to avoid the complexity of solving differential equations for non-linear perturbations directly. we have shown, for the case of the double massive inflation with the arbitrary constant metric in the field space, even the mass of two scalar fields are equal, the non-Gaussianity parameter may not vanish....

  4. 378. Disformal coupling between dark energy and dark matter and the dynamics of the universe
    Mr Stharporn Sapa

    Oral

    We consider a cosmological model where the coupling between dark energy and dark matter is motivated by disformal transformation. We consider the case where conformal coefficient depends only on scalar field while disformal coefficient depends both on the scalar field and its kinetic energy. We found that there exist new two classes of fixed point when disformal coefficient depend on both...
