“…Because we use both joint detections and non-detections with fluence upper limits in our analysis to constrain the population hyper-parameters, the rates we quote here are more optimistic than the joint GW-GRB detection rates in other work (Howell et al 2019). The addition of next-generation GRB instruments like THESEUS Stratta et al 2018), BurstCube (Racusin et al 2017), and HERMES (Fuschino et al 2019) coincident with the gravitational-wave detector upgrades to Voyager or even A+ sensitivity will greatly increase the all-sky duty cycle of the GRB satellite network and the joint detection rate. We note that based on the results in Figs.…”

Gamma-ray burst (GRB) prompt emission is highly beamed, and understanding the jet geometry and beaming configuration can provide information on the poorly understood central engine and circum-burst environment. Prior to the advent of gravitational-wave astronomy, astronomers relied on observations of jet breaks in the multi-wavelength afterglow to determine the GRB opening angle, since the observer's viewing angle relative to the system cannot be determined from the electromagnetic data alone. Gravitational-wave observations, however, provide an independent measurement of the viewing angle. We describe a Bayesian method for determining the geometry of short GRBs using coincident electromagnetic and gravitational-wave observations. We demonstrate how an ensemble of multi-messenger detections can be used to measure the distributions of the jet energy, opening angle, Lorentz factor, and angular profile of short GRBs; we find that for a population of 100 such observations, we can constrain the mean of the opening angle distribution to within 10 • regardless of the angular emission profile. Conversely, the constraint on the energy distribution depends on the shape of the profile, which can be distinguished.

“…The instrument extends the detection of transients to lower energies, with a low energy threshold at 4 keV. ECLAIRs will be launched on the SVOM satellite in 2021 (Wei et al 2016), Stratta et al (2018) and the instrument is now under construction in various French institutes. The next sections give a detailed description of the instrument and draws some lessons learned during the construction of the detection plane.…”

Designing large pixelated CdTe detection planes for hard X-ray transients detection

et al. 2019

View full text Add to dashboard Cite

We discuss the need for very large detection planes for the detection of hard X-ray transients in the multi-messenger era that started with the quasi-simultaneous detection of GRB 170817A by Fermi /GBM and IN-TEGRAL/SPI on one hand and the gravitational waves event GW 170817, detected by the LVC collaboration, on the other hand. Then, we present a brief survey of current and future instruments and their expected sensitivity, pointing the fact that the gain in the number of GRBs is achieved by future projects thanks to their larger field of view rather than to their larger effective area. Based on our experience with SVOM /ECLAIRs, we then address various problems associated with the realization of very large detection planes (≥ 1m 2 ), and we demonstrate that CdTe detectors are well suited for this task. We conclude with a discussion of some key parameters that must be taken into account in the realization of instruments based on these detectors. We hope that this paper will motivate the elaboration of detailed proposals of large area wide-field hard X-ray monitors that will be crucially needed in the next decade.Keywords Gamma-ray instrumentation · Gamma-ray bursts · X-ray transients PACS 95.55.Ka

“…ET would detect binary black hole (BH) mergers up to z ∼ 20, and NS-NS mergers up to z 2 − 3, with rates of order 10 5 − 10 6 events per year [9,28,29]. Depending on the network of telescopes and GRB satellites that will be operating at that time, in a few years ET could collect hundreds of NS-NS coalescences with observed electromagnetic counterpart [29,30]. sirens do not measure the same luminosity distance as electromagnetic probes [19,20,[31][32][33][34][35][36][37][38][39].…”

Gaussian processes reconstruction of modified gravitational wave propagation

et al. 2020

Recent work has shown that modified gravitational wave (GW) propagation can be a powerful probe of dark energy and modified gravity, specific to GW observations. We use the technique of Gaussian processes, that allows the reconstruction of a function from the data without assuming any parametrization, to measurements of the GW luminosity distance from simulated joint GW-GRB detections, combined with measurements of the electromagnetic luminosity distance by simulated DES data. For the GW events we consider both a second-generation LIGO/Virgo/Kagra (HVLKI) network, and a third-generation detector such as the Einstein Telescope. We find that the HVLKI network at target sensitivity, with O(15) neutron star binaries with electromagnetic counterpart, could already detect deviations from GR at a level predicted by some modified gravity models, and a third-generation detector such as ET would have a remarkable discovery potential. We discuss the complementarity of the Gaussian processes technique to the (Ξ0, n) parametrization of modified GW
