Error Analysis for Solving Elliptic Interface Problems with Randomized Neural Networks
Jun Hu, Sidi Wu
This paper presents a unified error analysis of randomized neural networks (RaNNs) for elliptic interface problems. We first derive an integral representation of Barron functions u…
Revisiting FRB 20121102A: milliarcsecond localisation and a decreasing dispersion measure
M. P. Snelders, J. W. T. Hessels, J. Huang +27
FRB 20121102A is the original repeating fast radio burst (FRB) source and also the first to be localised to milliarcsecond precision using very-long-baseline interferometry (VLBI).…
A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment
Alexandra M. Moroianu, Shivani Bhandari, Maria R. Drout +38
We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of fi…
A Hyperactive FRB Pinpointed in an SMC-Like Satellite Host Galaxy
M. Bhardwaj, M. P. Snelders, J. W. T. Hessels +24
Precise localizations of fast radio bursts (FRBs) are essential for uncovering their host galaxies and immediate environments. We present the milliarcsecond-precision European VLBI…
A Repeating Fast Radio Burst Source in a Low-Luminosity Dwarf Galaxy
Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon +48
We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localizatio…
Milliarcsecond Localisation of the Hyperactive Repeating FRB 20220912A
Danté M. Hewitt, Shivani Bhandari, Benito Marcote +23
We present very-long-baseline interferometry (VLBI) observations of the hyperactive repeating FRB 20220912A using the European VLBI Network (EVN) with an EVN-Lite setup. We detecte…
Preserving your skies since 1988 -- Committee on Radio Astronomy Frequencies (CRAF) -- Periodic Review 2011-2021
Committee on Radio Astronomy Frequencies, Benjamin Winkel, Simon Garrington +43
The Committee on Radio Astronomy Frequencies (CRAF) is an Expert Committee of the European Science Foundation. It aims to provide a cost-effective single voice on frequency protect…
A burst storm from the repeating FRB 20200120E in an M81 globular cluster
K. Nimmo, J. W. T. Hessels, M. P. Snelders +20
The repeating fast radio burst (FRB) source FRB 20200120E is exceptional because of its proximity and association with a globular cluster. Here we report bursts detected with…
X-ray burst and persistent emission properties of the magnetar SGR 1830-0645 in outburst
G. Younes, C. -P. Hu, K. Bansal +18
We report on NICER X-ray monitoring of the magnetar SGR 1830-0645 covering 223 days following its October 2020 outburst, as well as Chandra and radio observations. We present the m…
A repeating fast radio burst source in a globular cluster
F. Kirsten, B. Marcote, K. Nimmo +63
Fast radio bursts (FRBs) are exceptionally luminous flashes of unknown physical origin, reaching us from other galaxies (Petroff et al. 2019). Most FRBs have only ever been seen on…
Surprising Evolution of the Parsec-scale Faraday Rotation Gradients in the Jet of the BL Lac Object B1803+784
M. Mahmud, D. C. Gabuzda, V. Bezrukovs
Several multi-frequency polarization studies have shown the presence of systematic Faraday Rotation gradients across the parsec-scale jets of Active Galactic Nuclei (AGN), taken to…
