Tiny-box: A tool for the versatile development and characterization of low noise fast X-ray imaging detectors

Kavli Affiliate: Steven Allen | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Steven Allen, Jack Hirschman, Glenn Morris | Summary: X-ray Charge Coupled Devices (CCDs) have been the workhorse for soft X-ray astronomical instruments for the past quarter century. They provide broad energy response, extremely low electronic read noise, and good energy resolution in soft […]

Interferometric Constraints on Spacelike Coherent Rotational Fluctuations

Kavli Affiliate: Rainer Weiss | First 5 Authors: Jonathan W. Richardson, Ohkyung Kwon, H. Richard Gustafson, Craig Hogan, Brittany L. Kamai | Summary: Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interferometers. One arm of each interferometer is bent $90^{circ}$ […]

A possible bright ultraviolet flash from a galaxy at redshift z ~ 11

Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In the optical sky, minutes-duration transients from cosmological distances are rare. Known objects that give rise to such transients include gamma-ray bursts (GRBs), the most luminous explosions in the universe that have been detected […]
