Pulsar timing analysis in the presence of correlated noise
pulsars: general – methods: data analysis
2011/7/27
Pulsar timing observations are usually analysed with least-square-fitting procedures under the assumption that the timing residuals are uncorrelated (statistically "white"). Pulsar observers are well ...
Photon noise limited radiation detection with lens-antenna coupled Microwave Kinetic Inductance Detectors
Photon noise limited radiation Microwave Kinetic Inductance Detectors
2011/7/21
Microwave Kinetic Inductance Detectors (MKIDs) have shown great potential for sub-mm instrumentation because of the high scalability of the technology. Here we demonstrate for the first time in the su...
Random matrix approach in search for weak signals immersed in background noise
Random matrix approach search signals immersed background noise
2011/7/14
We present new, original and alternative method for searching signals coded in noisy data. The method is based on the properties of random matrix eigenvalue spectra. First, we describe general ideas a...
Reconstructing signals from noisy data with unknown signal and noise covariance
statistics, information theory, statistical mechanics
2011/7/12
We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point ...
