TL;DR
This paper reviews how multimessenger gamma-ray burst observations, especially from the THESEUS-BTA program, can test fundamental cosmological principles and address discrepancies in parameter measurements across different scales.
Contribution
It introduces the potential of multimessenger gamma-ray burst observations for testing core cosmological models and discusses systematic effects influencing these tests.
Findings
Multimessenger GRB observations can probe cosmological models up to redshift z~10.
Selection effects significantly impact the interpretation of cosmological relations.
THESEUS-BTA program aims to enhance these tests with future observations.
Abstract
Modern Multimessenger Astronomy is a powerful instrument for performing cosmological crucial tests of the Standard Cosmological Model in the wide redshift interval up to . This is principally important for discussion related to discrepancies between local and global measurements of cosmological parameters. We present a review of multimessenger gamma-ray burst observations currently conducted and planed for THESEUSBTA cooperative program. Such observations give a unique opportunity to test the fundamental foundations of cosmological models: gravitation theory; cosmological principle of homogeneity and isotropy of large-scale distribution of matter; and space expansion paradigm. Important role of various selection effects leading to systematic distortions of true cosmological relations is discussed.
