Weak Lensing Measurement of Filamentary Structure with the SDSS BOSS and Subaru Hyper Suprime-Cam Data

Posted by klaurent Tokyo

Kavli Affiliate: Naoshi Sugiyama | Summary:We report the weak lensing measurement of filaments between Sloan Digital Sky Survey (SDSS) III/Baryon Oscillation Spectroscopic Survey (BOSS) CMASS galaxy pairs at $zsim0.55$, using the Subaru Hyper Suprime-Cam (HSC) first-year galaxy shape catalogue. Despite of the small overlap of $140$ deg$^2$ between these surveys we detect the filament lensing […]

A fast-switching magnet serving a spallation-driven ultracold neutron source

Posted by klaurent Cambridge

Kavli Affiliate: A. C. Davis | Summary:A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility. The facility possesses unique operational requirements: a time-averaged beam current of 40~$μ$A with the ability to switch the beam on or off […]

Precision Measurement of the Weak Charge of the Proton

Posted by klaurent Cambridge

Kavli Affiliate: A. C. Davis | Summary:The fields of particle and nuclear physics have undertaken extensive programs to search for evidence of physics beyond that explained by current theories. The observation of the Higgs boson at the Large Hadron Collider completed the set of particles predicted by the Standard Model (SM), currently the best description […]

Catching butterflies in the sky: Extended catalog of winged or X-shaped radio sources from the latest FIRST data release

Posted by klaurent Peking

Kavli Affiliate: Xuebing Wu | Summary:We present a catalog of 290 "winged" or X-shaped radio galaxies (XRGs) extracted from the latest (2014 December 17) data release of the "Very Large Array Faint Images of the Radio Sky at Twenty centimeter." We have combined these radio images with their counterparts in the TIFR GMRT sky survey […]

Reflections On the Anomalous ANITA Events: The Antarctic Subsurface as a Possible Explanation

Posted by klaurent Stanford

Kavli Affiliate: Dustin M. Schroeder | Summary:The ANITA balloon experiment was designed to detect radio signals initiated by neutrinos and cosmic ray air showers. These signals are typically discriminated by the polarization and phase inversions of the radio signal. The reflected signal from cosmic rays suffer phase inversion compared to a direct tau neutrino event. […]

The far-infrared polarization spectrum of Rho Ophiuchi A from HAWC+/SOFIA observations

Posted by klaurent Stanford

Kavli Affiliate: Rodriguez Enrique Lopez | Summary:We report on polarimetric maps made with HAWC+/SOFIA toward Rho Oph A, the densest portion of the Rho Ophiuchi molecular complex. We employed HAWC+ bands C (89 $μ$m) and D (154 $μ$m). The slope of the polarization spectrum was investigated by defining the quantity R_DC = p_D/p_C, where p_C […]
