- Title
- (1) Interpreting the double-ridge structure in high-frequency time-distance diagrams, (2) Close loop correction of residual atmospheric dispersion in high-contrast imaging systems.
- Abstract
- (optional) (2) For direct imaging of habitable exoplanets from ground-based telescopes, it is crucial to correct for all the wavefront errors. One such error comes atmospheric refraction, in this talk, I will talk about why it is important to correct for refraction to the highest degree and how it can be achieved.

- Title
- Superluminous Supernovae: Current Status of Research
- Abstract
- Many supernovae are discovered in last decade with peak luminosity one-two orders of magnitude higher than for normal supernovae of known types. They are called Superluminous supernovae: SLSNe. This is a challenge for theory, since even normal supernovae are not yet completely understood from the first principles. The models explaining those events with the minimum energy budget involve multiple ejections of mass in presupernova stars. The radiative shocks produced in collisions of those shells may provide the required power of light. This class of the models is refered to as “interacting” supernovae. I concentrate on the non-trivial problems of this scenario for SLSNe: stability of the shells, on “bumps” in the light curves, and on the broad lines often observed in their spectra.

- ” The nature of the accretion flow in Active Galactic Nuclei”
- Abstract
-
Understanding the accretion flow in AGN has recently become an important cosmological problem as AGN feedback via winds and the jet is now known to control the star formation powered growth of galaxies. However, we have no current global models for the power carried by these components, nor do we know how they tie to the accretion flow, which is not surprising as we do not understand the structure of the accretion flow itself. I will review what we know about the way the observed spectral energy distribution changes with mass and mass accretion rate, and propose a global model for the accretion flow structure which includes the soft X-ray excess.
I use this accretion flow structure as the basis for a proposed quantitive model for the power carried by winds and jets. - 連絡先
