Cryogenic Focus Measurement System for a Wide-Field Infrared Space Telescope

Kavli Affiliate: James Bock | First 5 Authors: Samuel S. Condon, Stephen Padin, James Bock, Howard Hui, Phillip Korngut | Summary: We describe a technique for measuring focus errors in a cryogenic, wide-field, near-infrared space telescope. The measurements are made with a collimator looking through a large vacuum window, with a reflective cold filter to […]

Forecasting constraints on the no-hair theorem from the stochastic gravitational wave background

Kavli Affiliate: Ke Wang | First 5 Authors: Chen Tan, Ke Wang, , , | Summary: Although the constraints on general relativity (GR) from each individual gravitational-wave (GW) event can be combined to form a cumulative estimate of the deviations from GR, the ever-increasing number of GW events used also leads to the ever-increasing computational […]

L-function genera and applications

Kavli Affiliate: Andrei Okounkov | First 5 Authors: David Kazhdan, Andrei Okounkov, , , | Summary: We introduce equivariant L-genera associated to actions of Galois and related groups on algebraic varieties. We explain the role which these L-genera play in the spectral analysis of Eisenstein series. We also discuss the natural categorification of L-genera and […]

Constraints on the origin of the radio synchrotron background via angular correlations

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Elisa Todarello, Marco Regis, Federico Bianchini, Jack Singal, Enzo Branchini | Summary: The origin of the radio synchrotron background (RSB) is currently unknown. Its understanding might have profound implications in fundamental physics or might reveal a new class of radio emitters. In this work, we consider the […]

Generation of Isocurvature from Curvature Inhomogeneities on Super-Horizon Scales

Kavli Affiliate: Albert Stebbins | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Here it is shown 1) how isocurvature inhomogeneities correlated on causally disconnected (super-horizon) scales are generated from curvature inhomogeneities which are known to be correlated on these scales 2) that super-horizon isocurvature generation is nearly inevitable for non-equilibrium chemical processes […]

The Milky Way Tomography with Subaru Hyper Suprime-Cam. I. Halo substructures

Kavli Affiliate: Masahiro Takada | First 5 Authors: Yoshihisa Suzuki, Masashi Chiba, Yutaka Komiyama, Kohei Hayashi, Masayuki Tanaka | Summary: We analyze the photometric data in the Wide layer of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) over $sim 1,200$ deg$^{2}$ to uncover new halo substructures beyond the distance, $D_{odot}sim$ 30 kpc, from the Sun. […]

Revealing Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bingxiao Xu, Yingjie Peng, , , | Summary: In the previous work of Xu & Peng (2021), we investigated the structural and environmental dependence on quenching in the nearby universe. In this work we extend our investigations to higher redshifts by combining galaxies from SDSS and ZFOURGE […]
