Combining a Diffraction-Limited Coronagraph with Fiber Nulling: A Demonstration of Serially Coupling Different Nullers
Satoshi Itoh, Taro Matsuo, Reiki Kojima +3
We present experimental results of an efficient small-IWA (1 ) high contrast imaging approach realized by co-optimizing a coronagraph front-end with a fiber nulling 2nd…
Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)
Keigo Enya, Kenta Yoneta, Naoshi Murakami +20
In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…
Reconstructing a large-scale matter-density contrast profile to reconcile Pantheon+ supernovae with DESI DR2 BAO in an inhomogeneous universe
Toshifumi Futamase, Reiki Kojima, Masanori Tomonaga
The Hubble parameters measured by the DESI DR2 BAO observations show a significant discrepancy from the prediction of the standard cosmological model. This discrepancy, together wi…
Experimental Validation for Serial Conjunction of Diffraction-limited Coronagraph and Fiber Nuller
Satoshi Itoh, Taro Matsuo, Reiki Kojima +2
We report the experimental results of a serially conjoined nuller system, which combines a type of Lyot coronagraph with a fiber nuller. The utilized one-dimensional diffraction-li…
Experimental Verification of a One-Dimensional Diffraction-Limit Coronagraph
Satoshi Itoh, Taro Matsuo, Shunsuke Ota +5
We performed an experimental verification of a coronagraph. As a result, we confirmed that, at the focal region where the planetary point spread function exists, the coronagraph sy…
