QCD Axion Search with ILC Beam Facility

Posted by klaurent March 11, 2022March 21, 2022Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Hajime Fukuda, Hidetoshi Otono, Satoshi Shirai, , | Summary: One of the most promising methods to search for axions is a light-shining-through-walls (LSW) experiment. In this work, we discuss the possibility of performing an LSW experiment at the ILC experiment, where photon beams are generated for positron […]

Cohesin erases genomic-proximity biases to drive stochastic Protocadherin expression for proper neural wiring

Posted by klaurent March 11, 2022March 21, 2022UCSF

Kavli Affiliate: Daniele Canzio | Authors: Lea Kiefer, Gabrielle Isabelle F. Servito, Sandy M Rajkumar, Jennifer Langen, Anna Chiosso, Alexander Buckley, Elizabeth S. Cha, Adan Horta, Michael H Mui and Daniele Canzio | Summary: Clustered Protocadherin (Pcdh) proteins act as cell-surface recognition barcodes for neural circuit formation. Neurites expressing the same barcode repel each other, […]

An extended mixed finite element method for elliptic interface problems

Posted by klaurent March 11, 2022March 21, 2022Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Pei Cao, Jinru Chen, Feng Wang, , | Summary: In this paper, we propose an extended mixed finite element method for elliptic interface problems. By adding some stabilization terms, we present a mixed approximation form based on Brezzi-Douglas-Marini element space and the piecewise constant function space, and […]

Not so fuzzy: excluding FDM with sizes and stellar kinematics of ultra-faint dwarf galaxies

Posted by March 11, 2022Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Neal Dalal, Andrey Kravtsov, , , | Summary: We use observations of ultra-faint dwarf (UFD) galaxies to constrain the particle mass of ultra-light dark matter. Potential fluctuations created by wave interference in virialized "fuzzy" dark matter (FDM) halos dynamically heat stellar orbits in UFDs, some of which […]

Snowmass2021 CMB-HD White Paper

Posted by dbos March 11, 2022Cambridge

Kavli Affiliate: Blake Sherwin | First 5 Authors: The CMB-HD Collaboration, :, Simone Aiola, Yashar Akrami, Kaustuv Basu | Summary: CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep (0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a survey would answer many outstanding questions about the […]

LINNA: Likelihood Inference Neural Network Accelerator

Posted by klaurent March 10, 2022March 28, 2022Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Chun-Hao To, Eduardo Rozo, Elisabeth Krause, Hao-Yi Wu, Risa H. Wechsler | Summary: Bayesian posterior inference of modern multi-probe cosmological analyses incurs massive computational costs. For instance, depending on the combinations of probes, a single posterior inference for the Dark Energy Survey (DES) data had a […]

Soft limits of the wavefunction in exceptional scalar theories

Posted by klaurent March 10, 2022March 28, 2022Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Noah Bittermann, Austin Joyce, , , | Summary: We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft theorems that are satisfied by wavefunction coefficients in the limit where one of the external momenta is scaled […]
