Cosmological Constraint on Vector Mediator of Neutrino-Electron Interaction in light of XENON1T Excess

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: Recently, the XENON1T collaboration reported an excess in the electron recoil energy spectrum. One of the simplest new physics interpretation is a new neutrino-electron interaction mediated by a light vector particle. However, for the parameter region favored […]

Possible Time Correlation Between Jet Ejection and Mass Accretion for RW Aur A

Kavli Affiliate: Moritz Guenther | First 5 Authors: Michihiro Takami, Tracy L. Beck, P. Christian Schneider, Hans Moritz Guenther, Marc White | Summary: For the active T-Taur star RW Aur A we have performed long-term (~10 yr) monitoring observations of (1) jet imaging in the [Fe II] 1.644-micron emission line using Gemini-NIFS and VLT-SINFONI; (2) […]

Discovery of a Cooper-Pair Density Wave State in a Transition-Metal Dichalcogenide

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Xiaolong Liu, Yi Xue Chong, Rahul Sharma, J. C. Séamus Davis, | Summary: Pair density wave (PDW) states are defined by a spatially modulating superconductive order-parameter. To search for such states in transition metal dichalcogenides (TMD) we use high-speed atomic-resolution scanned Josephson-tunneling microscopy (SJTM). We […]

Dark Energy Survey Year 1 Results: Constraining Baryonic Physics in the Universe

Kavli Affiliate: Aaron Roodman | First 5 Authors: Hung-Jin Huang, Tim Eifler, Rachel Mandelbaum, Gary M. Bernstein, Anqi Chen | Summary: Measurements of large-scale structure are interpreted using theoretical predictions for the matter distribution, including potential impacts of baryonic physics. We constrain the feedback strength of baryons jointly with cosmology using weak lensing and galaxy […]

Designing angle-independent structural colors using Monte Carlo simulations of multiple scattering

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Victoria Hwang, Anna B. Stephenson, Solomon Barkley, Soeren Brandt, Ming Xiao | Summary: Disordered nanostructures with correlations on the scale of visible wavelengths can show angle-independent structural colors. These materials could replace dyes in some applications because the color is tunable and resists photobleaching. However, designing […]

Amplify-and-Forward Relaying for Hierarchical Over-the-Air Computation

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jie Xu, Vincent K. N. Lau, Shuguang Cui, | Summary: This paper studies a hierarchical over-the-air computation (AirComp) network over a large area, in which multiple relays are exploited to facilitate data aggregation from massive WDs. We present a two-phase amplify-and-forward (AF) relaying protocol. In […]

The thermal-radiative wind in the neutron star low mass X-ray binary GX 13+1

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Ryota Tomaru, Chris Done, Ken Ohsuga, Hirokazu Odaka, Tadayuki Takahashi | Summary: We fit the observed high ionisation X-ray absorption lines in the neutron star binary GX13+1 with a full simulation of a thermal-radiative wind. This uses a radiation hydrodynamic code coupled to Monte Carlo radiation transfer […]

Structure of neutron stars in massive scalar-tensor gravity

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Christopher J. Moore, Ulrich Sperhake, Michalis Agathos, Davide Gerosa | Summary: We compute families of spherically symmetric neutron-star models in two-derivative scalar-tensor theories of gravity with a massive scalar field. The numerical approach we present allows us to compute the resulting spacetimes out to infinite […]

Covariance of the redshift-space matter power spectrum after reconstruction

Kavli Affiliate: Chiaki Hikage | First 5 Authors: Chiaki Hikage, Ryuichi Takahashi, Kazuya Koyama, , | Summary: We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases […]
