SubsidieMeestersRelativistic Jets in the Multimessenger Era
This project aims to enhance the detection and understanding of gravitational wave signals from relativistic jets in multimessenger astronomy, focusing on their implications in various cosmic events.
Projectdetails
Introduction
The birth of multimessenger Astronomy is unfolding in front of our eyes, largely thanks to incredible observational developments. The new observations challenge theory on numerous frontiers and my goal is to address some of those and to open others.
Relativistic Jets
Relativistic jets are the classical multimessenger sources, typically dominating the observed signature of the objects that launch them. Relativistic jets even have their own gravitational waves signature, Jet-GW, that arises from the jet acceleration.
Jet-GW Signal
This signal, largely ignored so far, is a memory type wave that enables us to “see” directly the jet launching process, and is probably the only way to do so. Detection of Jet-GWs is extremely challenging and they may be easily missed if they are not looked for.
Program Goals
In this program, I aim to achieve the understanding of these signals essential for their detection. In addition, I propose to explore observational implications of relativistic jets as they are manifested in:
- Binary neutron star mergers (BNS)
- Gamma-ray bursts (GRBs)
- A subpopulation of supernovae (SNe) that harbor hidden jets
- Tidal disruption events (TDEs)
Research Focus
I will study the basic physics involved, carry out large scale simulations, and probe new observational results. I will focus on new physics, for example, photodissociation of heavy nuclei during jet propagation within BNS ejecta, that hasn’t been considered so far.
TDEs as Natural Laboratories
Powerful jets appear in some TDEs, but not in others. This makes TDEs natural laboratories to pursue the major open question: under which conditions are powerful jets launched?
Commonalities Among Different Events
Although BNS, GRBs, SNe, and TDEs appear to be very different, their jets have a lot in common. Understanding them requires analysis of the same basic physics and application of similar numerical tools.
Conclusion
This joint study that breaks artificial conceptual barriers will be highly beneficial and fruitful.
