“…This could explain why offsets of localised FRBs (relative to their hosts' centres) appear to be different from galactic neutron stars (Bhandari et al 2022). In addition, an FRB has recently been detected in an old globular cluster (Kirsten et al 2021). Globular clusters are the hosts of recycled millisecond pulsars (Zhao & Heinke 2022), whose properties, namely rapid spin and low magnetic fields, are consistent with our model.…”

Recent observations of coherent radiation from the Crab pulsar (Bĳ et al 2021) suggest the emission is driven by an ultra -relativistic ( ∼ 10 4 ), cold plasma flow. A relativistically expanding plasma shell can compress the ambient magnetic field, like a moving mirror, and thus produce coherent radiation whose wavelength is shorter than that of the ambient medium by 2 . This mechanism has been studied in the past by Colgate and Noerdelinger (1971), in the context of radio loud supernova explosions. In this work we propose that a similar mechanism drives the coherent emission in fast radio bursts. The high Lorenz factors dramatically lower the implied energy and magnetic field requirements, allowing the spin down energy of regular (or even recycled), fast spinning pulsars, rather than slow spinning magnetars, to explain FRBs. We show that this model can explain the frequency and the time evolution of observed FRBs, as well as their duration, energetics and absence of panchromatic counterparts. We also predict that the peak frequency of sub pulses decline with observation time as obs ∝ −1/2 obs . Unfortunately, with current capabilities it is not possible to constrain the shape of the curve obs ( obs ). Finally, we find that a variation of this model can explain weaker radio transients, such as the one observed from a galactic magnetar. In this variant, the shock wave produces low frequency photons which are then Compton scattered to the GHz range.

“…Narrowband emissions or flux knots have now been observed in giant pulses of PSR J0540-6919 (Geyer et al 2021) and the Crab pulsar (Thulasiram & Lin 2021), which have been attributed to the intrinsic emission behavior of the source. Moreover, the discovery of a FRB in a globular cluster near M81 (Bhardwaj et al 2021;Kirsten et al 2022;Majid et al 2021) does put forward a strong case for the relationship between giant pulses and FRBs (Nimmo et al 2022). Another outburst comparable to FRB luminosity from a Galactic source will surely help us better constrain the energy gap between these two phenomena.…”

We present a multiband study of FRB 20180916B, a repeating source with a 16.3 day periodicity. We report the detection of four, one, and seven bursts from observations spanning 3 days using the upgraded Giant Metrewave Radio Telescope (300–500 MHz), the Canadian Hydrogen Intensity Mapping Experiment (400–800 MHz) and the Green Bank Telescope (600–1000 MHz), respectively. We report the first ever detection of the source in the 800–1000 MHz range along with one of the widest instantaneous bandwidth detections (200 MHz) at lower frequencies. We identify 30 μs wide structures in one of the bursts at 800 MHz, making it the lowest frequency detection of such structures for this fast radio burst thus far. There is also a clear indication of high activity of the source at a higher frequency during earlier phases of the activity cycle. We identify a gradual decrease in the rotation measure over two years and no significant variations in the dispersion measure. We derive useful conclusions about progenitor scenarios, energy distribution, emission mechanisms, and variation of the downward drift rate of emission with frequency. Our results reinforce that multiband observations are an effective approach to study repeaters, and even one-off events, to better understand their varying activity and spectral anomalies.

“…Estimates in the literature for the MW's halo contribution to DM range from 25 pc cm −3 to ∼80 pc cm −3 (Prochaska & Neeleman 2018;Shull & Danforth 2018;Prochaska & Zheng 2019;Yamasaki & Totani 2020), large enough to impact estimates of extragalactic contributions. Though it has been argued that the MW halo could contribute as little as 10 pc cm −3 (Keating & Pen 2020), we conservatively use a flat Recent work has shown that the burst source is coincident with a globular cluster in the M81 system (Kirsten et al 2022), so the disk of M81 and the globular cluster make no or little contribution to the DM. If we take the assumed minimum MW halo contribution of DM mw,halo = 25 pc cm −3 , only 23-28 pc cm −3 are contributed by M81ʼs halo along with a minimal contribution from the IGM.…”

Redshift Estimation and Constraints on Intergalactic and Interstellar Media from Dispersion and Scattering of Fast Radio Bursts

A sample of 14 FRBs with measured redshifts and scattering times is used to assess contributions to dispersion and scattering from the intergalactic medium (IGM), galaxy halos, and the disks of host galaxies. The IGM and galaxy halos contribute significantly to dispersion measures (DMs) but evidently not to scattering, which is then dominated by host galaxies. This enables the usage of scattering times for estimating DM contributions from host galaxies and also for a combined scattering–dispersion redshift estimator. Redshift estimation is calibrated using the scattering of Galactic pulsars after taking into account different scattering geometries for Galactic and intergalactic lines of sight. The DM-only estimator has a bias of ∼0.1 and rms error of ∼0.15 in the redshift estimate for an assumed ad hoc value of 50 pc cm−3 for the host galaxy’s DM contribution. The combined redshift estimator shows less bias by a factor of 4 to 10 and a 20%–40% smaller rms error. We find that values for the baryonic fraction of the ionized IGM f igm ≃ 0.85 ± 0.05 optimize redshift estimation using dispersion and scattering. Our study suggests that 2 of the 14 candidate galaxy associations (FRB 20190523A and FRB 20190611B) should be reconsidered.
