AbstractSince 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and their successors will increase in sensitivity, discovering thousands of stellar-mass binaries. In the 2030s, the space-based LISA will provide gravitational-wave observations of massive black holes binaries. Between the $\sim 10$ ∼ 10 –103 Hz band of ground-based observatories and the $\sim 10^{-4}$ ∼ 1 0 − 4 –10− 1 Hz band of LISA lies the uncharted decihertz gravitational-wave band. We propose a Decihertz Observatory to study this frequency range, and to complement observations made by other detectors. Decihertz observatories are well suited to observation of intermediate-mass ($\sim 10^{2}$ ∼ 1 0 2 –104M⊙) black holes; they will be able to detect stellar-mass binaries days to years before they merge, providing early warning of nearby binary neutron star mergers and measurements of the eccentricity of binary black holes, and they will enable new tests of general relativity and the Standard Model of particle physics. Here we summarise how a Decihertz Observatory could provide unique insights into how black holes form and evolve across cosmic time, improve prospects for both multimessenger astronomy and multiband gravitational-wave astronomy, and enable new probes of gravity, particle physics and cosmology.

Gravitational waves were predicted by Albert Einstein more than a century ago, but only in 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) was able to detect them. The gravitational wave phenomenon can be compared to spreading water from a lake after a stone has been thrown into it. Here, gravitational wave generation comes from an astronomical binary system formed by black holes or neutron stars. However, unlike the water, the amplitude of those gravitational waves is on a scale smaller than a proton’s size. Despite this, we can describe it with simple equations in a phenomenological way. We can model those waves on a regular computer using post Newtonian physics. Here we were able to generate gravitational waves from computational simulations and make its data analyze. When a gravitational wave is detected in the real-world problem, there is a great interest in establishing the physical features of the astronomical bodies involved in the process. In this way, we propose applying a simple neural network to receive the gravitational wave data and infer information about the astronomical bodies’ mass. The experimental results show that a simple neural network can extract mass information from the gravitational wave data. The recognition process proposed is much more straightforward than the complex computation based on numerical relativity for gravitational wave data analysis.

AbstractPossible formation mechanisms of massive close binary black holes that can merge in the Hubble time to produce powerful gravitational wave bursts detected during advanced LIGO O1 science run are briefly discussed. The pathways include the evolution from field low-metallicity massive binaries, the dynamical formation in globular clusters and primordial black holes. Low effective black hole spins inferred for LIGO GW150914 and LTV151012 events are discussed. Population synthesis calculations of the expected spin and chirp mass distributions from the standard field massive binary formation channel are presented for different metallicities (from zero-metal Population III stars up to solar metal abundance). We conclude that that merging binary black holes can contain systems from different formation channels, discrimination between which can be made with increasing statistics of mass and spin measurements from ongoing and future gravitational wave observations.
