Transformer models for astrophysical time series and the GRB prompt-afterglow relation
Oliver M. Boersma, Eliot H. Ayache, Joeri van Leeuwen
Transformer models have recently become very successful in the natural language domain. Their value as sequence-to-sequence translators there, also makes them a highly interesting…
Pulsar revival in neutron star mergers: multi-messenger prospects for the discovery of pre-merger coherent radio emission
A. J. Cooper, O. Gupta, Z. Wadiasingh +5
We investigate pre-merger coherent radio emission from neutron star mergers arising due to the magnetospheric interaction between compact objects. We consider two plausible radiati…
DeepGlow: an efficient neural-network emulator of physical afterglow models for gamma-ray bursts and gravitational-wave events
Oliver M. Boersma, Joeri van Leeuwen
Gamma-ray bursts (GRBs) and double neutron-star merger gravitational wave events are followed by afterglows that shine from X-rays to radio, and these broadband transients are gene…
First release of Apertif imaging survey data
Elizabeth A. K. Adams, B. Adebahr, W. J. G. de Blok +56
(Abridged) Apertif is a phased-array feed system for WSRT, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated survey program started on 1 July 2019, with th…
A fast radio burst with sub-millisecond quasi-periodic structure
Inés Pastor-Marazuela, Joeri van Leeuwen, Anna Bilous +31
Fast radio bursts (FRBs) are extragalactic radio transients of extraordinary luminosity. Studying the diverse temporal and spectral behaviour recently observed in a number of FRBs…
Investigating the detection rates and inference of gravitational-wave and radio emission from black hole neutron star mergers
Oliver M. Boersma, Joeri van Leeuwen
Black hole neutron star (BHNS) mergers have recently been detected through their gravitational-wave (GW) emission. BHNS mergers could also produce electromagnetic (EM) emission as…
A search for radio emission from double-neutron star merger GW190425 using Apertif
Olivér Boersma, Joeri van Leeuwen, Elizabeth A. K. Adams +26
Detection of the electromagnetic emission from coalescing binary neutron stars (BNS) is important for understanding the merger and afterglow. We present a search for a radio counte…
Chromatic periodic activity down to 120 MHz in a Fast Radio Burst
Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34
Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…
Forecasts for detecting the gravitational-wave memory effect with Advanced LIGO and Virgo
Oliver M. Boersma, David A. Nichols, Patricia Schmidt
The detection of gravitational waves (GWs) from binary black holes (BBHs) has allowed the theory of general relativity to be tested in a previously unstudied regime: that of strong…
A bright, high rotation-measure FRB that skewers the M33 halo
Liam Connor, Joeri van Leeuwen, L. C. Oostrum +37
We report the detection of a bright fast radio burst, FRB\,191108, with Apertif on the Westerbork Synthesis Radio Telescope (WSRT). The interferometer allows us to localise the FRB…
