“…Ho we ver, due to the lack of ultra-deep high-resolution imaging, and thus SL constraints far from the cluster centre, these external DM haloes were not directly constrained in these models. 1 This now changes due to the unprecedented sensitivity and spatial resolution of the JWST (Gardner et al 2006 ;McEl w ain et al 2023 ), the advent of which has already revealed numerous new SL features in several clusters and enabled significant improvements to their SL models (Caminha et al 2022 ;Hsiao et al 2022 ;Pascale et al 2022 ;Diego et al 2023 ;Mahler et al 2023 ;Meena et al 2023b ;Williams et al 2023 ). Most recently, the JWST targeted Abell 2744 in the framework of the Ultra-deep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) program (PIs: I. Labb é & R. Bezanson;Bezanson et al 2022 ) for wide-field ultra-deep imaging of the cluster and its surroundings (it was also observed to lesser depth in two other JWST programs; see Section 2 ).…”

We present a new parametric lens model for the massive galaxy cluster Abell 2744 based on new ultra-deep JWST imaging taken in the framework of the UNCOVER program. These observations constitute the deepest JWST images of a lensing cluster to date, adding to existing deep Hubble Space Telescope (HST) images and the recent JWST ERS and DDT data taken for this field. The wide field-of-view of UNCOVER (∼45 arcmin2) extends beyond the cluster’s well-studied central core and reveals a spectacular wealth of prominent lensed features around two massive cluster sub-structures in the north and north-west, where no multiple images were previously known. We identify 75 new multiple images and candidates of 17 sources, 43 of which allow us, for the first time, to constrain the lensing properties and total mass distribution around these extended cluster structures using strong lensing (SL). Our model yields an effective Einstein radius of θE, main = 23.2″ ± 2.3″ for the main cluster core (for zs = 2), enclosing a mass of M( < θE, main) = (7.7 ± 1.1) × 1013 M⊙, and θE, NW = 13.1″ ± 1.3″ for the newly discovered north-western SL structure enclosing M( < θE, NW) = (2.2 ± 0.3) × 1013 M⊙. The northern clump is somewhat less massive with θE, N = 7.4″ ± 0.7″ enclosing M( < θE, N) = (0.8 ± 0.1) × 1013 M⊙. We find the northern sub-structures of Abell 2744 to broadly agree with the findings from weak lensing (WL) analyses and align with the filamentary structure found by these previous studies. Our model in particular reveals a large area of high magnification values between the various cluster structures, which will be paramount for lensed galaxy studies in the UNCOVER field. The model is made publicly available to accompany the first UNCOVER data release.

“…As the accretion takes place, electromagnetic (EM) radiation is produced from tenuous hot plasma in the disk and, in most cases, from the magnetically-dominated outgoing jet launched from the poles of the BHs and its interactions with the environment (see e.g [9][10][11]). This radiation may be detectable by multiple EM instruments, such as FERMI [12], the Event Horizon Telescope [13], PanSTARRS [14], the HST [15], and JWST [16], to name just a few. Gravitational waves (GWs) from inspiralling BHBHs or even their BHdisk remnants [17,18] have been, or are expected to be, de-tected either by ground-or space-based GW observatories (see e.g.…”

We perform general relativistic simulations of magnetized, accreting disks onto spinning black hole binaries with mass ratio q ≡ M1,irr/M2,irr = 1, 2 and 4. The magnitude of the individual dimensionless black hole spins are all χ = 0.26 and lie either along the initial orbital plane or 45 • above it. We evolve these systems throughout the late inspiral, merger and postmerger phases to identify the impact of the black hole spins and the binary mass ratio on any jet and their electromagnetic (Poynting) signatures. We find that incipient jets are launched from both black holes regardless of the binary mass ratio and along the spin directions as long as the force-free parameter B 2 /(8 πρ0) in the funnel and above their poles is larger than one. At large distances the two jets merge into a single one. This effect likely prevents the electromagnetic detection of individual jets. As the accretion rate reaches a quasistationary state during the late predecoupling phase, we observe a sudden amplification of the outgoing Poynting luminosity that depends on the binary mass ratio. Following merger, the sudden change in the direction of the spin of the black hole remnant with respect to the spins of its progenitors causes a reorientation of the jet. The remnant jet drives a single, high-velocity, outward narrow beam collimated by a tightly wound, helical magnetic field which, in turn, boosts the Poynting luminosity. This effect is nearly mass-ratio independent. During this process, a kink is produced in the magnetic field lines, confining the jet. The kink propagates along the jet but rapidly decays, leaving no memory of the spin-shift. Our results suggest that the merger of misaligned, low-spinning, black hole binary mergers in low-mass disks may not provide a viable scenario to explain X-shaped radio galaxies if other features are not taken into account. However, the sudden changes in the outgoing luminosity at merger may help to identify mergers of black holes in active galactic nuclei, shedding light on black hole growth mechanisms and the observed co-evolution of their host galaxies.
