Noise Reduction Methods for Large-scale Intensity-mapping Measurements with Infrared Detector Arrays
Grigory Heaton, Walter Cook, James Bock +10
Intensity mapping observations measure galaxy clustering fluctuations from spectral-spatial maps, requiring stable noise properties on large angular scales. We have developed speci…
