Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, , | Summary: The cosmic microwave background (CMB) observation by the Planck satellite precisely determines primordial curvature fluctuations on larger scales than $mathcal O(1),mathrm{Mpc}$, while the small-scale curvature fluctuation is still less constrained. The constraint on small-scale fluctuations is highly improved […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, F. Abudinén, L. Aggarwal | Summary: We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $ phi_{3} $ (also known as~$gamma$) using a model-independent Dalitz plot analysis of linebreak $B^+to Dleft(K_{S}^{0}h^{+}h^{-}right)h^+$, where $D$ is either a $D^0$ or $bar{D}{}^0$ meson and […]

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: We use a non-linear lattice simulation to study a model of axion inflation where the inflaton is coupled to a U(1) gauge field through Chern-Simons interaction. This kind of models have already been studied with a […]

Philcox, Takahiro Nishimichi, Marko Simonović, Masahiro Takada | Summary: We study the information content of the angle-averaged (monopole) redshift space galaxy bispectrum. The main novelty of our approach is the use of a systematic tree-level perturbation theory model that includes galaxy […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson, Blake D. Sherwin, Anthony Challinor | Summary: We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing the lensing noise in measurements of the […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Volodymyr Takhistov, Valeri Vardanyan, Ying-li Zhang, | Summary: Primordial black holes (PBHs) from the early Universe constitute an attractive dark matter candidate. First detections of black hole-neutron star (BH-NS) candidate gravitational wave events by the LIGO/Virgo collaboration, GW200105 and GW200115, already prompted speculations about non-astrophysical […]

Kavli Affiliate: T. Higuchi | First 5 Authors: F. Abudinén, I. Adachi, R. Adak, K. Adamczyk, L. Aggarwal | Summary: This paper reports a study of $B to K^{*}gamma$ decays using $62.8pm 0.6$ fb$^{-1}$ of data collected during 2019–2020 by the Belle II experiment at the SuperKEKB $e^{+}e^{-}$ asymmetric-energy collider, corresponding to $(68.2 pm 0.8) […]

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Takayuki Toda, Yuki Sakurai, Hirokazu Ishino, Tomotake Matsumura, Kunimoto Komatsu | Summary: The polarization modulator unit for the low-frequency telescope in LiteBIRD employs an achromatic half-wave plate (AHWP). It consists of five layers of a-cut sapphire plate, which are stacked based on a Pancharatnam recipe. In this […]

Kavli Affiliate: Masahiro Takada | First 5 Authors: Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada, Hironao Miyatake, | Summary: We present the results obtained from the full-shape cosmology analysis of the redshift-space power spectra for 4 galaxy samples of the SDSS-III BOSS DR12 galaxy catalog over $0.2 < z < 0.75$. For the theoretical template, we […]
