Relativistic Astrophysics: We study the dynamics and emission processes of relativistic jets at different scales, their interaction with stars and host galaxies, as well as relativistic flows in X-ray and gamma-ray binary stars. Moreover, we also explore the dynamics and electromagnetic and gravitational-wave emission of binary neutron star mergers and post-merger remnants. Multi-messenger aspects associated with neutron star crustal fracture in such mergers is also a topic of our investigation along with the computation of shadows of compact objects sourced by accretion disks.
Cosmology: We study the formation and evolution of galaxies and cosmic voids, and explore the effects on galaxy clusters of cosmological shock waves, turbulence in the intracluster medium, and cosmological magnetic fields. The new cosmological simulations to be carried out in this project will produce synthetic galaxies directly comparable to those observed by current and new generations of telescopes.
Gravitational-Wave Astronomy: The project provides direct contributions to observations from the science runs of the LIGO-Virgo-KAGRA (LVK) detector network. Specific activities involve waveform modeling of compact binary coalescences, asteroseismology of core collapse supernovae, data analysis (including machine learning approaches) of transient sources, development of new pipelines and searches during the LVK observational run O4, and electromagnetic follow-up observations of gravitational-wave events.
The CIPROM/2022/49 project has a strong computational profile as it makes heavy use of high-performance computing to achieve the aforementioned goals. By developing and exploiting fairly specific numerical tools, the project will bridge the results from the simulations with multi-messenger astronomical data, both for electromagnetic signals and gravitational-wave signals.
The CIPROM/2022/49 project is interdisciplinary in its scientific scope with implications in many disciplines in physics. It also provides opportunities for its early-stage participants to strengthen their skills and acquire new ones with substantial benefits for their future careers.
