Fitting the nonlinear matter bispectrum by the Halofit approach
Ryuichi Takahashi, Takahiro Nishimichi, Toshiya Namikawa +5
We provide a new fitting formula of the matter bispectrum in the nonlinear regime calibrated by high-resolution cosmological -body simulations of cold dark matter (CDM,…
The Weak Lensing Bispectrum Induced By Gravity
D. Munshi, T. Namikawa, T. D. Kitching +5
Recent studies have demonstrated that {\em secondary} non-Gaussianity induced by gravity will be detected with a high signal-to-noise (S/N) by future and even by on-going weak lens…
Internal delensing of Cosmic Microwave Background polarization B-modes with the POLARBEAR experiment
S. Adachi, M. A. O. Aguilar Faúndez, Y. Akiba +51
Using only cosmic microwave background polarization data from the POLARBEAR experiment, we measure -mode polarization delensing on subdegree scales at more than significanc…
Microwave multiplexing on the Keck Array
Ari Cukierman, Zeeshan Ahmed, Shawn Henderson +82
We describe an on-sky demonstration of a microwave-multiplexing readout system in one of the receivers of the Keck Array, a polarimetry experiment observing the cosmic microwave ba…
CMB-S4 Decadal Survey APC White Paper
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consid…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
CMB-S4 Science Case, Reference Design, and Project Plan
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
CMB-HD: An Ultra-Deep, High-Resolution Millimeter-Wave Survey Over Half the Sky
Neelima Sehgal, Simone Aiola, Yashar Akrami +37
A millimeter-wave survey over half the sky, that spans frequencies in the range of 30 to 350 GHz, and that is both an order of magnitude deeper and of higher-resolution than curren…
Evidence for the Cross-correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam
Toshiya Namikawa, Yuji Chinone, Hironao Miyatake +72
We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) {\it polarization} data, and the cosmic sh…
CMB Constraints on the Stochastic Gravitational-Wave Background at Mpc scales
Toshiya Namikawa, Shohei Saga, Daisuke Yamauchi +1
We present robust constraints on the stochastic gravitational waves (GWs) at Mpc scales from the cosmic microwave background (CMB) data. CMB constraints on GWs are usually characte…
BICEP2 / Keck Array XI: Beam Characterization and Temperature-to-Polarization Leakage in the BK15 Dataset
Keck Array, BICEP2 Collaborations, : +76
Precision measurements of cosmic microwave background (CMB) polarization require extreme control of instrumental systematics. In a companion paper we have presented cosmological co…
Science from an Ultra-Deep, High-Resolution Millimeter-Wave Survey
Neelima Sehgal, Ho Nam Nguyen, Joel Meyers +66
Opening up a new window of millimeter-wave observations that span frequency bands in the range of 30 to 500 GHz, survey half the sky, and are both an order of magnitude deeper (abo…
