"From multi-wavelength to multi-spectrum astronomy"
Marica Branchesi, Postdoctoral Fellow, DiSBeF - Università 'Carlo Bo' di Urbino
Multi-wavelength electromagnetic (EM) astronomy has helped us build a more complete picture of the Universe. The light from each part of the EM spectrum contributes valuable and unique information about the complexity of small and large-scale structure.
The new frontier in observational astrophysics is the detection of gravitational waves (GW). This is not another wavelength of light, but instead an entirely new spectrum! The first GW detections are upcoming. Combining EM and GW observations will give us deeper information about extremely energetic astrophysical and cosmological phenomena.
A pioneering EM observation follow-up program of candidate GW events has been performed during the recent LIGO/Virgo GW detectors run. It involved ground- and space-based EM facilities observing the sky at optical, X-ray and radio wavelengths. I will present an overview of the EM follow-up program and the EM image analysis.
