The first 7 months of the 2020 X-ray outburst of the magnetar SGR J1935+2154
Alice Borghese, Francesco Coti Zelati, Gian Luca Israel +10
The magnetar SGR J1935+2154 underwent a new active episode on 2020 April 27-28, when a forest of hundreds of X-ray bursts and a large enhancement of the persistent flux were detect…
Overview of the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD) Project
The CHORD Collaboration, Kevin Bandura, Leonid Belostotski +49
The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation wideband radio interferometer currently being constructed and commissioned at the Domini…
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…
Optimising the FRB Search Pipeline for the Northern Cross Radio Telescope
Hayley Camilleri, Alessio Magro, Andrea Geminardi +8
FRB search pipelines are being developed to operate under strict real-time constraints while maintaining sensitivity to short-duration transient signals. In incoherent dedispersion…
The Northern Cross Fast Radio Burst project -- III. The FRB-magnetar connection in a sample of nearby galaxies
Davide Pelliciari, Gianni Bernardi, Maura Pilia +18
Fast radio bursts (FRBs) are millisecond radio transients observed at cosmological distances. The nature of their progenitors is still a matter of debate, although magnetars are in…
The First High Frequency Technosignature Search Survey with the Sardinia Radio Telescope
Lorenzo Manunza, Alice Vendrame, Luca Pizzuto +30
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz. In this paper, we extend the sear…
Performance analysis of the Karhunen-Loève Transform for artificial and astrophysical transmissions: denoising and detection
Matteo Trudu, Maura Pilia, Gregory Hellbourg +6
In this work, we propose a new method of computing the Karhunen-Loève Transform (KLT) applied to complex voltage data for the detection and noise level reduction in astronomical s…
Long-term study of the 2020 magnetar-like outburst of the young pulsar PSRJ1846-0258 in Kes 75
Rajath Sathyaprakash, Nanda Rea, Francesco Coti Zelati +14
Magnetar-like activity has been observed in a large variety of neutron stars. PSR J1846-0258 is a young 327 ms radio-quiet pulsar with a large rotational power ($\sim 8 \times 10^{…
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…
