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…
The gauge-invariant formulation of the local expansion rate driven by the local average density in an inhomogeneous universe
Masanori Tomonaga, Masumi Kasai, Toshifumi Futamase
The Hubble tension casts a blight on the standard cosmology. As a possible solution to the problem, the local variation of the expansion rate has been proposed where the spatial av…
On the gauge invariance of the locally averaged Friedmann Universe and the Hubble tension
Masanori Tomonaga, Toshifumi Futamase
The Hubble tension cast a blight on the standard cosmology. As a possible attitude to the problem, the local variation of the expansion rate in an inhomogeneous cosmology has been…
New highly precise weak gravitational lensing flexions measurement method based on ERA method
Yuki Okura, Toshifumi Futamase
Weak gravitational lensing flexions are a kind of weak lensing distortion which are defined as the spin 1 and spin 3 combinations of the third order derivatives of gravitational le…
Detection of Cosmic Magnification via Galaxy Shear -- Galaxy Number Density Correlation from HSC Survey Data
Xiangkun Liu, Dezi Liu, Zucheng Gao +5
We propose a novel method to detect cosmic magnification signals by cross-correlating foreground convergence fields constructed from galaxy shear measurements with background galax…
Standard candles and sirens rescue
Aniket Agrawal, Teppei Okumura, Toshifumi Futamase
We show that future observations of binary neutron star systems with electromagnetic counterparts together with the traditional probes of low- and high-redshift Type Ia supernovae…
