Yang, Jun (author), Paragi, Zsolt (author), Frey, Sándor (author), Gurvits, L. (author), Liao, Mai (author), Liu, Xiang (author), Cui, Lang (author), Yang, Xiaolong (author), Chen, Wen (author)Dwarf galaxies are characterized by a very low luminosity and low mass. Because of significant accretion and ejection activity of massive black holes, some dwarf galaxies also host low-luminosity active galactic nuclei (AGNs). In a few dwarf AGNs, very long baseline interferometry (VLBI) observations have found faint non-thermal radio...journal article 2023

(author), Paragi, Zsolt (author), Perger, Krisztina (author), Zheng, Zhenya (author)Blazars are a sub-class of quasars with Doppler boosted jets oriented close to the line of sight, and thus efficient probes of supermassive black hole growth and their environment, especially at high redshifts. Here we report on Very Long Baseline Interferometry observations of a blazar J0906 + 6930 at z = 5.47, which enabled the detection of...journal article 2020

Cao, H.M. (author), Frey, S. (author), Gurvits, L. (author), Yang, J. (author), Hong, X.Y. (author), Paragi, Z. (author), Deller, A.T. (author), Ivezic, Z. (author)A patch of sky in the SDSS Stripe 82 was observed at 1.6 GHz with Very Long Baseline Interferometry (VLBI) using the European VLBI Network (EVN). The data were correlated at the EVN software correlator at JIVE (SFXC). There are fifteen known mJy/sub-mJy radio sources in the target field defined by the primary beam size of a typical 30-m class...journal article 2014
