Towards precision particle background estimation for future X-ray missions: correlated variability between Chandra ACIS and AMS

Posted by klaurent MIT

Kavli Affiliate: Richard Foster | Summary:A science goal of many future X-ray observatories is mapping the cosmic web through deep exposures of faint diffuse sources. Such observations require low background and the best possible knowledge of the remaining unrejected background. The dominant contribution to the background above 1-2 keV is from Galactic Cosmic Ray protons. […]

Single electron Sensitive Readout (SiSeRO) X-ray detectors: Technological progress and characterization

Posted by klaurent Stanford

Kavli Affiliate: Daniel R. Wilkins | Summary:Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a depleted internal gate beneath the transistor channel. The transistor source-drain current is modulated by the transfer […]

2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. Soliman, P. A. R. Ade, Z. Ahmed, M. Amiri, D. Barkats | Summary: Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measure primordial gravitational waves (PGWs), the sign of inflation after the Big-Bang […]

Basolateral amygdala and orbitofrontal cortex, but not dorsal hippocampus, are necessary for the control of reward-seeking by occasion setters

Posted by klaurent Hopkins

Kavli Affiliate: Patricia Janak | Authors: Kurt M Fraser and Patricia H Janak | Summary: ABSTRACT Reward-seeking in the world is driven by cues that can have ambiguous predictive and motivational value. To produce adaptive, flexible reward-seeking it is necessary to exploit occasion setters, other distinct features in the environment, to resolve the ambiguity of […]
