Turning off the Lights: How Dark is Dark Matter? [PDF]
, 2010 We consider current observational constraints on the electromagnetic charge of dark matter. The velocity dependence of the scattering cross-section through the photon gives rise to qualitatively different constraints than standard dark matter scattering ...

Temperature Sensors Integrated into a CMOS Image Sensor
Proceedings, 2017 In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is

Carrier scattering approach to the origins of dark current in mid- and far-infrared (terahertz) quantum-well intersubband photodetectors (QWIPs) [PDF]
, 2001 A carrier scattering approach is taken in an analysis of the affect on the dark current of extending the operating wavelength of conventional bound to continuum quantum-well intersubband photodetectors. It is found that both the sequential tunneling and

Similarities Between Proton and Neutron Induced Dark Current Distribution in CMOS Image Sensors [PDF]
, 2012 Several CMOS image sensors were exposed to neutron or proton beams (displacement damage dose range from 4 TeV/g to 1825 TeV/g) and their radiation-induced dark current distributions are compared.

Particle Dark Matter Constraints from the Draco Dwarf Galaxy [PDF]
, 2002 It is widely thought that neutralinos, the lightest supersymmetric particles, could comprise most of the dark matter. If so, then dark halos will emit radio and gamma ray signals initiated by neutralino annihilation.
