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…
A clustering-based self-calibration of the richness-to-mass relation of CAMIRA galaxy clusters out to in the Hyper Suprime-Cam survey
I-Non Chiu, Teppei Okumura, Masamune Oguri +3
We perform a self-calibration of the richness-to-mass (-) relation of CAMIRA galaxy clusters with richness at redshift by modeling redshift-space tw…
Constraining neutrino mass and dark energy with peculiar velocities and lensing dispersions of Type Ia supernovae
Aniket Agrawal, Teppei Okumura, Toshifumi Futamase
We show that peculiar velocities of Type Ia supernovae can be used to derive constraints on the sum of neutrino masses, , and dark energy equation of state, $w = w_0+w_a(1-a)…
Comparing approximate methods for mock catalogues and covariance matrices III: Bispectrum
Manuel Colavincenzo, Emiliano Sefusatti, Pierluigi Monaco +19
We compare the measurements of the bispectrum and the estimate of its covariance obtained from a set of different methods for the efficient generation of approximate dark matter ha…
Comparing approximate methods for mock catalogues and covariance matrices II: Power spectrum multipoles
Linda Blot, Martin Crocce, Emiliano Sefusatti +19
We study the accuracy of several approximate methods for gravitational dynamics in terms of halo power spectrum multipoles and their estimated covariance matrix. We propagate the d…
Comparing approximate methods for mock catalogues and covariance matrices I: correlation function
Martha Lippich, Ariel G. Sánchez, Manuel Colavincenzo +19
This paper is the first in a set that analyses the covariance matrices of clustering statistics obtained from several approximate methods for gravitational structure formation. We…
Non-Gaussianity of Inflationary Gravitational Waves from the Field Equation
Aniket Agrawal
We demonstrate equivalence of the in-in formalism and Green's function method for calculating the bispectrum of primordial gravitational waves generated by vacuum fluctuations of t…
Tensor Non-Gaussianity from Axion-Gauge-Fields Dynamics : Parameter Search
Aniket Agrawal, Tomohiro Fujita, Eiichiro Komatsu
We calculate the bispectrum of scale-invariant tensor modes sourced by spectator SU(2) gauge fields during inflation in a model containing a scalar inflaton, a pseudoscalar axion a…
Large Tensor Non-Gaussianity from Axion-Gauge Fields Dynamics
Aniket Agrawal, Tomohiro Fujita, Eiichiro Komatsu
We show that an inflation model in which a spectator axion field is coupled to an SU(2) gauge field produces a large three-point function (bispectrum) of primordial gravitational w…
Generating Log-normal Mock Catalog of Galaxies in Redshift Space
Aniket Agrawal, Ryu Makiya, Chi-Ting Chiang +3
We present a public code to generate a mock galaxy catalog in redshift space assuming a log-normal probability density function (PDF) of galaxy and matter density fields. We draw g…
