Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Sunao Sugiyama, Toshiki Kurita, | Summary: Different cosmological probes, such as primary cosmic microwave background (CMB) anisotropies, CMB lensing, and cosmic shear, are sensitive to the primordial power spectrum (PPS) over different ranges of wavenumbers. In this paper, we combine the cosmic shear […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska, Simone Ferraro, Jessica N. Aguilar | Summary: The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-Zel’dovich effect (kSZ). We precisely measure […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Tomohiro Fujita, Ryodai Kawaguchi, Misao Sasaki, Yuichiro Tada, | Summary: We consider models of inflation that contain a transient non-slow-roll stage and investigate the conditions under which a dip appears in the power spectrum of the curvature perturbation. Using the $delta N$ formalism, we derive a general […]

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: Recently, it was shown that in the absence of gravity there exist non-$O(4)$-symmetric instanton solutions with finite action beyond Coleman’s instantons. In this paper, focusing on the false-vacuum decay in a single scalar field in flat Euclidean space, […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, J. K. Ahn | Summary: Using 983.0 $rm{fb}^{-1}$ and 427.9 $rm{fb}^{-1}$ data samples collected with the Belle and Belle II detectors at the KEKB and SuperKEKB asymmetric energy $e^+e^-$ colliders, respectively, we present studies of the Cabibbo-favored $Xi_c^+$ decays ${Xi_{c}^{+}to […]

Kavli Affiliate: Tom Melia | First 5 Authors: Qiuyue Liang, Tom Melia, , , | Summary: We define a relativistic version of the global symmetries responsible for the restricted mobility of fracton quasiparticles. The theories have a symmetry current that is proportional to a vector field that spontaneously breaks Lorentz boost symmetry. We argue that […]

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Thibaut Louis, Adrien La Posta, Zachary Atkins, Hidde T. Jense, Irene Abril-Cabezas | Summary: We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Telescope (ACT) data. These cover 19,000 deg$^2$ […]

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Shin’ichiro Ando, Kohei Hayashi, Shunichi Horigome, Masahiro Ibe, Satoshi Shirai | Summary: Self-interacting dark matter (SIDM) has been proposed to address small-scale challenges faced by the cold dark matter (CDM) paradigm, such as the diverse density profiles observed in dwarf galaxies. In this study, we analyze the […]
