AI Thread Summary
The paper discusses the potential of the LISA space interferometer to detect ringdown waves emitted by newly formed supermassive black holes, which are characterized by discrete frequencies. The authors introduce a multi-mode formalism for detecting these signals, estimating black hole parameters, and testing the no-hair theorem of general relativity. They compute the expected signal-to-noise ratio for ringdown events and analyze the accuracy of parameter estimation and mode resolvability. Additionally, the impact of uncertainties in physical parameters, such as black hole spin and energy emissions, on black hole spectroscopy is examined. This research highlights LISA's capability in advancing our understanding of black hole physics.

On gravitational-wave spectroscopy of massive black holes with the space interferometer LISA

Authors: Emanuele Berti, Vitor Cardoso, Clifford M. Will
Comments: 44 pages, 21 figures, 10 tables
"Newly formed black holes are expected to emit characteristic radiation in the form of quasi-normal modes, called ringdown waves, with discrete frequencies. LISA should be able to detect the ringdown waves emitted by oscillating supermassive black holes throughout the observable Universe. We develop a multi-mode formalism, applicable to any interferometric detectors, for detecting ringdown signals, for estimating black hole parameters from those signals, and for testing the no-hair theorem of general relativity. Focusing on LISA, we use current models of its sensitivity to compute the expected signal-to-noise ratio for ringdown events, the relative parameter estimation accuracy, and the resolvability of different modes. We also discuss the extent to which uncertainties on physical parameters, such as the black hole spin and the energy emitted in each mode, will affect our ability to do black hole spectroscopy."

I am very interested in this paper by Berti, Cardoso, and Will. It sounds like LISA could potentially be used to detect ringdown waves emitted by newly formed black holes and that the authors develop a multi-mode formalism to do so. It would be interesting to know what kind of parameter estimation accuracy and resolution can be expected with LISA and how uncertainties on physical parameters might affect this.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
