Physically consistent gravitational waveform for capturing beyond general relativity effects in the compact object merger phase
Daiki Watarai, Atsushi Nishizawa, Kipp Cannon
The merger phase of compact binary coalescences is the strongest gravity regime that can be observed. To test the validity of general relativity (GR) in strong gravitational fields…
Robustness of Baryon Acoustic Oscillations Measurements with Photometric Redshift Uncertainties
Keitaro Ishikawa, Tomomi Sunayama, Atsushi J. Nishizawa +2
We investigate the robustness of baryon acoustic oscillations (BAO) measurements with a photometric galaxy sample using mock galaxy catalogues with various sizes of photometric red…
Line-of-sight structure of troughs identified in Subaru Hyper Suprime-Cam Year 3 weak lensing mass maps
Takumi Shimasue, Ken Osato, Masamune Oguri +2
We perform the weak lensing mass mapping analysis to identify troughs, which are defined as local minima in the mass map. Since weak lensing probes projected matter along the line-…
Quasar Luminosity Function at z = 7
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +41
We present the quasar luminosity function (LF) at , measured with 35 spectroscopically confirmed quasars at . The sample of 22 quasars from the Subaru High-…
Non-Linearity-Free prediction of the growth-rate using Convolutional Neural Networks
Koya Murakami, Indira Ocampo, Savvas Nesseris +2
The growth-rate of the large-scale structure of the Universe is an important dynamic probe of gravity that can be used to test for deviations from General Relativity. How…
Impact of astrophysical effects on the dark matter mass constraint with 21cm intensity mapping
Koya Murakami, Atsushi J. Nishizawa, Kentaro Nagamine +1
We present an innovative approach to constraining the non-cold dark matter model using a convolutional neural network (CNN). We perform a suite of hydrodynamic simulations with var…
