From the editors:
The world continues to deal with the pandemic, and we hope our readers continue to stay safe and healthy. Meanwhile, here's a reminder that the abstract deadline for the FRB2021 conference is only 1 week away - see below for registration links. And as usual, here's our round up of recent papers and news items on fast radio bursts, including a handful of late-breaking papers on a repeating fast radio burst source associated with a globular cluster in M81.
Papers of interest
Host Galaxies and Localizations
- A repeating fast radio burst source in a globular cluster; Kirsten et al., arXiv: 2105.11445
Observational Results
- The Location of Young Pulsar PSR J0837-2454: Galactic Halo or Local Supernova Remnant? Pol et al., arXiv: 2104.11680
- The Breakthrough Listen Search For Intelligent Life Near the Galactic Center I; Gajjar et al., arXiv: 2104.14148
"We also searched our 11.2 hours of deep observations of the GC and its surrounding region for Fast Radio Burst-like magnetars with the DM up to 5000 pc/cc with maximum pulse widths up to 90 ms at 6 GHz."
- AGILE Observations of Fast Radio Bursts; Verrecchia et al., arXiv: 2105.00685
- Kinematics of Crab Giant Pulses; Bij et al., arXiv: 2105.08851
"... this would support models that appeal to highly relativistic plasma to transform ambient magnetic structures to coherent GHz radio emission, be it for giant pulses or for potentially related sources, such as fast radio bursts."
- The Thousand-Pulsar-Array programme on MeerKAT III: Giant pulse characteristics of PSR J0540-6919; Geyer et al., arXiv: 2105.09096
"... several of the giant [pulses] display very narrow-band "flux knots" similar to those seen in many Fast Radio Bursts, which we assert cannot be due to scintillation or plasma lensing."
- A Bright Fast Radio Burst from FRB 20200120E with Sub-100-Nanosecond Structure; Majid et al., arXiv: 2105.10987
- Burst timescales and luminosities link young pulsars and fast radio bursts; Nimmo et al., arXiv: 2105.11446
- An analysis of the time-frequency structure of several bursts from FRB\,121102 detected with MeerKAT; Platts et al., arXiv: 2105.11822
Theory and Modeling
- Statistical properties of fast radio bursts elucidate their origins: magnetars are favoured over gamma-ray bursts; Xiang-Han Cui et al., arXiv: 2104.11617
- The Galactic neutron star population I -- an extragalactic view of the Milky Way and the implications for fast radio bursts; Chrimes et al., arXiv: 2105.04549
- FRBs Lensed by Point Masses I. Lens Mass Estimation for Doubly Imaged FRBs; Xuechun Chen et al., arXiv: 2105.05868
SGR 1935+2154 and other relevant magnetar results
- The life cycle of magnetars: a novel approach to estimate their ages; Tushar Mondal, arXiv: 2104.12698
- ALMA and NOEMA constraints on synchrotron nebular emission from embryonic superluminous supernova remnants and radio-gamma-ray connection; Murase et al., arXiv: 2105.05239
Algorithms and Instrumentation
- MeerCRAB: MeerLICHT Classification of Real and Bogus Transients using Deep Learning; Hosenie et al., arXiv: 2104.13950
- The Weizmann Fast Astronomical Survey Telescope (W-FAST): System Overview; Nir et al., arXiv: 2105.03436
- The EXTraS Project: Exploring the X-ray transient and variable sky; De Luca et al., arXiv: 2105.02895
From the Astronomer's Telegram
- Continued activity of the repeating FRB 20201124A (see previous issue) has led to a precise localization with the EVN (ATel 14603) and an upper limit on persistent emission at milliarcsecond scales.
- The ASKAP localization has now been revised (ATel 14592), with the low band (860 MHz) position now consistent with all the other reported positions, while the high band (1270 MHz) localization continues to show a systematic offset.
- Two bright bursts from FRB 20201124A were detected with the Onsala 25-m telescope at 1.4 GHz, with no simultaneous emission detected at 330 MHz with Westerbork 25-m (ATel 14605).
Software
- RTApipe, a framework to develop astronomical pipelines for the real-time analysis of scientific data; Parmiggiani et al., arXiv: 2105.08611
- rta-dq-lib: a software library to perform online data quality analysis of scientific data; Baroncelli et al., arXiv: 2105.08648
Upcoming meetings and conferences
FRB2021: The conference FRB2021 will happen online from July 28th to August 5th (with a break in the middle; this date range is based on UT). The conference will be free of charge!
- Please save the dates: see a PDF overview of the block programme and a zipfile of calendar appointments here.
- Please register and submit abstracts via this form.
- Note the deadline for abstracts: EXTENDED to June 1st, 2021. Registration without a talk/poster is available till July 16th, 2021.
Recent online talks of interest
Most talks and meetings are online for now, and many are available as recorded versions, so we are trying out a provisional section for public recorded talks. We welcome your feedback, and pointers to other talks of interest.
Do you have an item for future newsletters? Please send these via email to the editors (Emily and Shami) to be included in an upcoming issue.
