Correct estimate of the probability of false detection of the matched filter in weak-signal detection problems. III (Peak distribution method versus the Gumbel distribution method)

R. Vio, P. Andreani, A. Biggs +1

The matched filter (MF) represents one of the main tools to detect signals from known sources embedded in the noise. In the Gaussian case the noise is assumed to be the realization…

Matched filter in the low-number count Poisson noise regime: an efficient and effective implementation

Roberto Vio, Paola Andreani

The matched filter (MF) is widely used to detect signals hidden within the noise. If the noise is Gaussian, its performances are well-known and describable in an elegant analytical…

The correct estimate of the probability of false detection of the matched filter in the detection of weak signals. II. (Further results with application to a set of ALMA and ATCA data)

Roberto Vio, Clara Verges, Paola Andreani

The matched filter (MF) is one of the most popular and reliable techniques to the detect signals of known structure and amplitude smaller than the level of the contaminating noise.…

The bivariate K-band-submillimetre luminosity functions of the local HRS galaxy sample

P. Andreani, L. Spinoglio, A. Boselli +6

We study the relationship between the K-band and the sub-millimetre (submm) emissions of nearby galaxies by computing the bivariate K-band-submm luminosity function (BLF) of the He…

An approach for the detection of point-sources in very high resolution microwave maps

R. Vio, P. Andreani, E. P. R. G. Ramos +1

This paper deals with the detection problem of extragalactic point-sources in multi-frequency, microwave sky maps that will be obtainable in future cosmic microwave background radi…

Two modified ILC methods to detect point sources in Cosmic Microwave Background maps

R. Vio, P. Andreani, E. P. R. G. Ramos +1

We propose two detection techniques that take advantage of a small sky area approximation and are based on modifications of the "internal linear combination" (ILC) method, an appro…

Unevenly-sampled signals: a general formalism of the Lomb-Scargle periodogram

R. Vio, P. Andreani, A. Biggs

The periodogram is a popular tool that tests whether a signal consists only of noise or if it also includes other components. The main issue of this method is to define a critical…

A Statistical Analysis of the "Internal Linear Combination" Method in Problems of Signal Separation as in CMB Observations

R. Vio, P. Andreani

AIMS: The separation of foreground contamination from cosmic microwave background (CMB) observations is one of the most challenging and important problem of digital signal processi…

Stochastic modeling of kHz QPO light curves

R. Vio, P. Rebusco, P. Andreani +2

The Kluzniak & Abramowicz model explains high frequency, double peak, "3:2" QPOs observed in neutron star and black hole sources in terms of a non-linear parametric resonance betwe…
