Very Long Baseline Interferometry Observations of the Proposed Radio Counterpart of an EGRET Source
Patrik Milán Veres, Krisztina Éva Gabányi, Sándor Frey
We present high-resolution radio interferometric imaging observations of the radio source NVSS J182659+343113 (hereafter J1826+3431), the proposed radio counterpart of the -ray…
A method for checking high-redshift identification of radio AGNs
Tao An, Yingkang Zhang, Sandor Frey
In large-scale optical spectroscopic surveys, there are many objects found to have multiple redshift measurements due to the weakness of their emission lines and the different auto…
J1110+4817 -- a compact symmetric object candidate revisited
M. Krezinger, S. Frey, T. An +2
Compact symmetric objects (CSOs) are radio-emitting active galactic nuclei (AGNs) typically with a double-lobed radio structure confined to within 1 kpc. CSOs represent the earlies…
High-Resolution Radio Observations of Five Optically Selected Type 2 Quasars
Máté Krezinger, Sándor Frey, Zsolt Paragi +1
Many low-luminosity active galactic nuclei (AGNs) contain a compact radio core which can be observed with high angular resolution using very long baseline interferometry (VLBI). Co…
The Quest for Dual and Binary Supermassive Black Holes: A Multi-Messenger View
Alessandra De Rosa, Cristian Vignali, Tamara Bogdanović +27
The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-messenger era is compelling. Detecting dual active galactic nuclei (AGN) -- active SMBHs at…
Evolving parsec-scale radio structure in the most distant blazar known
Tao An, Prashanth Mohan, Yingkang Zhang +7
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,…
