Symposium S13  26 – 27 June 2017

The multi­frequency gravitational wave universe

Aims and scope

With the discovery of the first two cosmic sources of high frequency gravitational waves GW150914 and GW151226, the year 2016 marks the beginning of a new era of exploration of the universe.

The signal, detected by the Advanced LIGO detectors and coming from pairs of coalescing stellar black holes, carries exquisite information about their masses and spins, enabling us to explore new avenues of formation in a universe that would be invisible otherwise.

In 2016, LISA Pathfinder scored a fantastic success on the technology for gravitational wave observation in space beyond the planned requirements reaching sub-femto "g" in free fall quality. The way to LISA is thus almost fully paved.

LISA will be the first observatory in space able to explore the low frequency gravitational wave universe hosting a variety of sources from coalescing massive black holes, to wide compact object binaries in the Milky Way, to stellar black holes fated to coalesce in the LIGO band, demonstrating the synergy and connections between the two windows.

LIGO-Virgo are soon expected to detect neutron star-neutron star and black hole-neutron star coalescences that might display an electromagnetic counterpart across all astronomical bandwidth, with the potential of proving the origin of short gamma-ray bursts.

In the next few years we shall witness a tremendous effort in detecting the electromagnetic counterparts of LIGO-Virgo coalescence events and in the identification of dual or binary active black holes in merging galaxies.

This symposium will be dedicated to the exploration of the multi-frequency gravitational universe, touching themes showing commonalities and diversities across the whole observational band. We aim at disseminating knowledge and to favour a cross-fertilizing experience amongst fields normally considered complementary.

The Symposium will gather leading scientists active in the aforementioned fields, promoting review talks and giving the opportunity to young researchers to present their works.
