A Repeating Fast Radio Burst Source in a Low-luminosity Dwarf Galaxy

D. M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon, A. Yu. Kirichenko et autres

Abstract 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 Pinpointing REpeating ChIme Sources with EVN dishes repeater localization program on the European VLBI Network (EVN), …

A link between repeating and non-repeating fast radio bursts through their energy distributions

Franz Kirsten, O. S. Ould-Boukattine, Wolfgang Artur Herrmann, Marcin Gawroński et autres

Abstract Fast radio bursts (FRBs) are extremely energetic, millisecond-duration radio flashes that reach Earth from extragalactic distances. Broadly speaking, FRBs can be classified as repeating or (apparently) non-repeating. It is still unclear, however, whether the two types share a common physical origin …

Milliarcsecond Localization of the Repeating FRB 20201124A

Kenzie Nimmo, D. M. Hewitt, Jason W. T. Hessels, Franz Kirsten et autres

Abstract Very long baseline interferometric (VLBI) localizations of repeating fast radio bursts (FRBs) have demonstrated a diversity of local environments: from nearby star-forming regions to globular clusters. Here we report the VLBI localization of FRB 20201124A using an ad hoc array of …

Apertif: Phased array feeds for the Westerbork Synthesis Radio Telescope

W. A. van Cappellen, Tom A. Oosterloo, Marc A. W. Verheijen, Elizabeth A. K. Adams et autres

We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope that transforms this telescope into a high-sensitivity, wide-field-of-view L-band imaging and transient survey instrument. Using novel PAF technology, up to 40 …

Sub-arcsecond imaging with the International LOFAR Telescope: II. Completion of the LOFAR Long-Baseline Calibrator Survey

Neal J Jackson, Shruti Badole, John S. Morgan, Rajan Chhetri et autres

The Low-Frequency Array (LOFAR) Long-Baseline Calibrator Survey (LBCS) was conducted between 2014 and 2019 in order to obtain a set of suitable calibrators for the LOFAR array. In this paper we present the complete survey, building on the preliminary analysis published in …

LOFAR 144-MHz follow-up observations of GW170817

J. W. Broderick, T. W. Shimwell, K. Gourdji, A. Rowlinson et autres

ABSTRACT We present low-radio-frequency follow-up observations of AT 2017gfo, the electromagnetic counterpart of GW170817, which was the first binary neutron star merger to be detected by Advanced LIGO–Virgo. These data, with a central frequency of 144 MHz, were obtained with LOFAR, the …
