3D printed fiber-optic nanomechanical bioprobe

Sandor Kasas, Yuguang Chen, Jiangtao Zhou, Yiping Wang

Ultrasensitive nanomechanical instruments, e.g. atomic force microscopy (AFM), can be used to perform delicate biomechanical measurements and reveal the complex mechanical environment of biological processes. However, these instruments are limited because ...

The Sloan Digital Sky Survey Reverberation Mapping Project: Initial CIV Lag Results from Four Years of Data

Jean-Paul Richard Kneib, Yuguang Chen, Yue Shen, Feng Li

We present reverberation-mapping (RM) lags and black hole mass measurements using the C IV lambda 1549 broad emission line from a sample of 348 quasars monitored as a part of the Sloan Digital Sky Survey RM Project. Our data span four years of spectroscopi ...

Detecting galaxy-filament alignments in the Sloan Digital Sky Survey III

Yuguang Chen, Jonathan Andrew Blazek

Previous studies have shown the filamentary structures in the cosmic web influence the alignments of nearby galaxies. We study this effect in the LOWZ sample of the Sloan Digital Sky Survey using the 'Cosmic Web Reconstruction' filament catalogue. We find ...

The Sloan Digital Sky Survey Reverberation Mapping Project: Improving Lag Detection with an Extended Multiyear Baseline

Jean-Paul Richard Kneib, Yuguang Chen, Yue Shen, Feng Li

We investigate the effects of extended multiyear light curves (9 yr photometry and 5 yr spectroscopy) on the detection of time lags between the continuum variability and broad-line response of quasars at z greater than or similar to 1.5, and compare with t ...
