Analysis method for 3D power spectrum of projected tensor field with fast estimator and window convolution modelling: an application to intrinsic alignments

Kavli Affiliate: Masahiro Takada | First 5 Authors: Toshiki Kurita, Masahiro Takada, , , | Summary: Rank-2 tensor fields of large-scale structure, e.g. a tensor field inferred from shapes of galaxies, open up a window to directly access 2 scalar, 2 vector and 2 tensor modes, where the scalar fields can be measured independently from […]

The halo bispectrum as a sensitive probe of massive neutrinos and baryon physics

Kavli Affiliate: Jia Liu | First 5 Authors: Victoria Yankelevich, Ian G. McCarthy, Juliana Kwan, Sam G. Stafford, Jia Liu | Summary: The power spectrum has been a workhorse for cosmological studies of large-scale structure. However, the present-day matter distribution is highly non-Gaussian and significant cosmological information is also contained in higher-order correlation functions. Meanwhile, […]

Extracting high-order cosmological information in galaxy surveys with power spectra

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Yuting Wang, Gong-Bo Zhao, Kazuya Koyama, Will J. Percival, Ryuichi Takahashi | Summary: The reconstruction method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes for dark energy. After moving […]

Intensity interferometry for ultralight bosonic dark matter detection

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Hector Masia-Roig, Nataniel L. Figueroa, Ariday Bordon, Joseph A. Smiga, Yevgeny V. Stadnik | Summary: Ultralight bosonic dark matter (UBDM) can be described by a classical wave-like field oscillating near the Compton frequency of the bosons. If a measurement scheme for the direct detection of UBDM […]
