The galaxy luminosity function in the LAMOST Complete Spectroscopic Survey of Pointing Area at the Southern Galactic Cap

Posted by klaurent Peking

Kavli Affiliate: Xuebing Wu | Summary:We present optical luminosity functions (LFs) of galaxies in the $^0.1g$, $^0.1r$, and $^0.1i$ bands, calculated using data in $sim 40$ $deg^2$ sky area of LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in Southern Galactic Cap. Redshifts for galaxies brighter $r = 18.1$ were obtained mainly with LAMOST. In […]

Dark Matter Science in the Era of LSST

Posted by klaurent Stanford

Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Keith Bechtol, Alex Drlica-Wagner, Kevork N. Abazajian, Muntazir Abidi, Susmita Adhikari | Summary: Astrophysical observations currently provide the only robust, empirical measurements of dark matter. In the coming decade, astrophysical observations will guide other experimental efforts, while simultaneously probing unique regions of dark matter parameter space. […]

Discovery of the First Low-Luminosity Quasar at z > 7

Posted by klaurent Tokyo

Kavli Affiliate: Naoshi Sugiyama | Summary:We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. This quasar, HSC J124353.93+010038.5, has an order of magnitude lower luminosity than do the other known quasars at z > […]

An Eccentric Massive Jupiter Orbiting a Sub-Giant on a 9.5 Day Period Discovered in the Transiting Exoplanet Survey Satellite Full Frame Images

Posted by klaurent MIT

Kavli Affiliate: Edward Morgan | Summary:We report the discovery of TOI-172 b from the Transiting Exoplanet Survey Satellite (TESS) mission, a massive hot Jupiter transiting a slightly evolved G-star with a 9.48-day orbital period. This is the first planet to be confirmed from analysis of only the TESS full frame images, because the host star […]

The International Linear Collider. A Global Project

Posted by klaurent Tokyo

Kavli Affiliate: Hiroaki Aihara | Summary:A large, world-wide community of physicists is working to realise an exceptional physics program of energy-frontier, electron-positron collisions with the International Linear Collider (ILC). This program will begin with a central focus on high-precision and model-independent measurements of the Higgs boson couplings. This method of searching for new physics beyond […]

A compact actively damped vibration isolation platform for optical experiments in ultra-high vacuum

Posted by klaurent MIT

Kavli Affiliate: Peter Fritschel | Summary:We present a tabletop six-axis vibration isolation system, compatible with Ultra-High Vacuum (UHV), which is actively damped and provides 25 dB of isolation at 10 Hz and 65 dB at 100 Hz. While this isolation platform has been primarily designed to support optics in the Laser Interferometer Gravitational-Wave Observatory (LIGO) […]
