Abstract

The brightest events in a time series of cosmological transients obey an observation time dependence which is often overlooked. This dependence can be exploited to probe the global properties of electromagnetic and gravitational wave transients [1, 2]. We describe a new relation based on a peak flux-observation time distribution and show that it is invariant to the luminosity distribution of the sources [3]. Applying this relation, in combination with a new data analysis filter, to Swift gamma-ray burst data, we demonstrate that it can constrain their rate density.
