Radio and -ray activity in the jet of the blazar S5 0716714
Dae-Won Kim, Evgeniya V. Kravchenko, Alexander M. Kutkin +11
We explore the connection between the -ray and radio emission in the jet of the blazar 0716714 by using 15, 37, and 230 GHz radio and 0.1200 GeV -ray light curves spann…
Dual-frequency single-pulse study of PSR B0950+08
A. V. Bilous, J. M. Griessmeier, T. Pennucci +33
PSR B0950+08 is a bright non-recycled pulsar whose single-pulse fluence variability is reportedly large. Based on observations at two widely separated frequencies, 55 MHz (NenuFAR)…
Parabolic jet shape on parsec scales in high redshift AGN
E. E. Nokhrina, I. N. Pashchenko, A. M. Kutkin
Geometry of relativistic jets in active galaxies provides important information about mechanisms of launching, collimation and acceleration of plasma flow. We propose a new method…
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…
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…
The high brightness temperature of B0529+483 revealed by RadioAstron and implications for interstellar scattering
S. V. Pilipenko, Y. Y. Kovalev, A. S. Andrianov +22
The high brightness temperatures, K, detected in several active galactic nuclei by RadioAstron space VLBI observations challenge theoretical limits. R…
The core shift effect in the blazar 3C 454.3
A. M. Kutkin, K. V. Sokolovsky, M. M. Lisakov +10
Opacity-driven shifts of the apparent VLBI core position with frequency (the "core shift" effect) probe physical conditions in the innermost parts of jets in active galactic nuclei…
