The ICCUB is aninterdisciplinary center with more than 60 long term scientists, 20 engineersand 80 postdoctoral researchers (55% international) and PhD students (30%international) offering an international and multicultural environment. TheICCUB also hosts a vibrant fundamental research program in cosmology,astrophysics and particle physics, with a strong technology unit supporting ourparticipation in international collaborations in observational astronomy andexperimental particle physics.

The Unit of Excellence Maria de Maeztu recognition has been awarded by the Spanish Government in 2020 for the second time to the ICCUB, as a center with a highly competitive strategic research programmes in the frontiers of knowledge. Thanks to this recognition, it is avalaible in the Aid for pre-doc contracts for the training of doctors (FPI 2020 call) the following project, funded by the Ministry of Science and Innovation:

Understanding the origin of coalescing binary black holes in LIGO-Virgo from their eccentricities

The LIGO and Virgo interferometers have detected gravitational waves (GW) from several dozens of coalescing binary black hole (BBHs). Several formation channels are able to explain the BBH merger rate, leaving their origin an open question. The dynamical formation of BBHs in dense stellar systems is a promising model and it predicts that a fraction of BBHs have measurable orbital eccentricities, making this a "smoking gun" signal. Thanks to continuous improvements of GW detector sensitivity - to which the Technological Unit of the ICCUB is actively contributing - empirical constraints on BBH eccentricity are starting to arrive. You will use gravitational N-body simulations and a BBH population synthesis model to make predictions for the eccentricity distribution of BBHs that formed in all star clusters in the Universe. Then, by using Numerical Relativity techniques, you will infer eccentricities from the GW data and explore degeneracies with other binary parameters. You will join the ICCUB Virgo group, consisting of PhD students, post-docs, academics and technical staff who all share a passion for GW research. You will also join the Virgo Collaboration and work on the forefront of GW data analyses and interpretation. This project will provide valuable model predictions and test them with the wealth of GW data that is arriving as we speak to shed light on the origin of BHBs.
