Bridging dS/CFT and Celestial Holography via Ward-Takahashi Identities
Hideo Furugori, Naoki Ogawa, Sotaro Sugishita +1
In 2507.17558, we provide a map from a scalar theory on -dimensional Minkowski spacetime to a scalar theory with a continuous mass spectrum on -dimensional de Sitter…
Flat Space Holography via AdS/BCFT
Peng-Xiang Hao, Naoki Ogawa, Tadashi Takayanagi +1
In this paper, we study a new class of AdS/BCFT setups, where the world-volumes of end-of-the-world branes (EOW branes) are given by flat spaces, to explore flat space holography f…
Celestial Holography meets dS/CFT
Hideo Furugori, Naoki Ogawa, Sotaro Sugishita +1
We provide a concrete link between celestial amplitudes and cosmological correlators. We first construct a map from quantum field theories (QFTs) in -dimensional Euclidean s…
Celestial CFT from -WZW Model
Naoki Ogawa, Shunta Takahashi, Takashi Tsuda +1
Recently, there has been a growing interest in celestial holography, which is holography in asymptotically flat spacetimes. This holographic duality exhibits numerous mysterious an…
Celestial two-point functions and rectified dictionary
Hideo Furugori, Naoki Ogawa, Sotaro Sugishita +1
A naive celestial dictionary causes massless two-point functions to take the delta-function forms in the celestial conformal field theory (CCFT). We rectify the dictionary, involvi…
