Transient Relativistic eXplosions

Objective

The recent and upcoming deep and large field of view surveys has ascribed transient sources an ever-increasing role in 21st century astronomy. We propose to explore three relativistic transients: Compact binary mergers; Stellar disruption by massive black holes (TDEs) and Gamma-Ray Bursts (GRBs). Mergers are the prime targets of advanced Gravitational Waves (GW) detectors. Their detection will open a new window on the Universe. However localization, based on electromagnetic (EM) counterparts, that we propose to study here, is essential for GW Astronomy. TDEs provide a novel view on galactic centers’ massive black holes. However, TDE observations pose some puzzles, suggesting that a revision of the current tidal disruption theory is needed. New observations provide a wealth of data on GRBs and this is the time to determine their inner workings and to obtain a clear model for the prompt emission mechanism – a long standing puzzle. This project includes theoretical modeling of these events as well as phenomenology of the observations and even some data analysis and observations. Mergers, TDEs and GRBs, are tightly interconnected and share similar physical mechanisms. The theory of merger radio flares and of TDE’s radio emission draws, for example, on GRBs’ afterglow theory and the interpretation of TDE high-energy emission is based on concepts borrowed from the prompt emission of GRBs. A coordinated theoretical study will reveal and utilize the commonalities of these phenomena and has a strong potential to obtain far reaching results beyond the current state of the art with possible implications to other high energy astrophysical phenomena. While this is a theoretical proposal we address at all stages directly observational issues. Hence the proposal is closely related to observations - interpreting existing puzzling observations, predicting new ones or suggesting strategies how to obtain them.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
