The unseen host galaxy and high dispersion measure of a precisely-localised Fast Radio Burst suggests a high-redshift origin [PDF]
Monthly notices of the Royal Astronomical Society, 2023
FRB 20210912A is a fast radio burst (FRB), detected and localised to sub-arcsecond precision by the Australian Square Kilometre Array Pathfinder. No host galaxy has been identified for this burst despite the high precision of its localisation and deep ...L. Marnoch, S. Ryder, C. James, A. Gordon, M. Sammons, J. Prochaska, Nicolas Tejos Adam T.

Monthly notices of the Royal Astronomical Society, 2019 We determined Faraday rotation measures (RMs) towards 137 pulsars in the northern sky, using Low-Frequency Array (LOFAR) observations at 110–190 MHz. This low-frequency RM catalogue, the largest to date, improves the precision of existing RM measurements C. Sobey, A. Bilous, J. Grießmeier, J. Hessels, A. Karastergiou, E. Keane, V. Kondratiev, M.

Astronomische Nachrichten, Volume 342, Issue 4, Page 675-695, May 2021., 2021 Abstract
We critically discuss recent articles by S. Hoffmann and N. Vogt on historical novae and supernovae (SNe) as well as their list of “24 most promising events” “with rather high probability to be a nova” (Hoffmann et al., AN, 2020, 341, 79 (P3)).Ralph Neuhäuser, Dagmar L.

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 4, April 2021., 2021 Abstract
The next‐generation, broadband geodetic very long baseline interferometry system, named VGOS, is being developed globally with an aim to achieve 1 mm accuracy for station positions. Currently, the systematic errors in VGOS broadband delays are still about 20 ps.Ming H. Xu, Tuomas Savolainen, Nataliya Zubko, Markku Poutanen, Susanne Lunz, Harald Schuh, Guang L.
