The nature of the methanol maser ring G23.65700.127. II. Expansion of the maser structure
Anna Bartkiewicz, Alberto Sanna, Marian Szymczak +3
Ring-like distributions of the 6.7 GHz methanol maser spots at milliarcsecond scales represent a family of molecular structures of unknown origin associated with high-mass young st…
Constraining very-high-energy and optical emission from FRB 121102 with the MAGIC telescopes
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +155
Fast radio bursts (FRBs) are bright flashes observed typically at GHz frequencies with millisecond duration, whose origin is likely extragalactic. Their nature remains mysterious,…
Nowhere to Hide: Radio-faint AGN in the GOODS-N field. I. Initial catalogue and radio properties
J. F. Radcliffe, M. A. Garrett, T. W. B. Muxlow +6
(Abridged) Conventional radio surveys of deep fields ordinarily have arc-second scale resolutions often insufficient to reliably separate radio emission in distant galaxies origina…
What are the megahertz peaked-spectrum sources?
Rocco Coppejans, David Cseh, Sjoert van Velzen +8
Megahertz peaked-spectrum (MPS) sources have spectra that peak at frequencies below 1 GHz in the observer's frame and are believed to be radio-loud active galactic nuclei (AGN). We…
