Fitted proper motions for the DR solution
We propose new estimates of the secular aberration drift, mainly due to the rotation of the Solar System about the Galactic center, based on up-to-date VLBI observations and and... -
Radio properties of faint BL Lacs
The advent of Fermi is changing our understanding on the radio and gamma-ray emission in Active Galactic Nuclei. Contrary to pre-Fermi ideas, BL Lac objects are found to be the... -
TANAMI monitoring of Centaurus A.
Centaurus A (Cen A) is the closest radio-loud active galactic nucleus. Very Long Baseline Interferometry (VLBI) enables us to study the spectral and kinematic behavior of the... -
LOFAR long baselines at 140MHz Calibrators
An efficient means of locating calibrator sources for international LOw Frequency ARray (LOFAR) is developed and used to determine the average density of usable calibrator... -
AGN in IFRS. VLBA observations
Infrared-faint radio sources (IFRS) form a new class of galaxies characterised by radio flux densities between tenths and tens of mJy and faint or absent infrared counterparts.... -
PKS 1502+106 15, 43 and 86GHz images
Blazars are among the most energetic objects in the Universe. In 2008 August, Fermi/LAT detected the blazar PKS 1502+106, which showed a rapid and strong gamma-ray outburst... -
VLBI images of 2 binary AGN candidates
The sources SDSS J113126.08-020459.2 and SDSS J110851.04+065901.4 are two double-peaked [OIII] emitting AGN, identified as candidate binary AGNs by optical and near infrared... -
The gNLS1 galaxy PKS 2004-447. VLBI images
Gamma-ray-detected radio-loud narrow-line Seyfert 1 (g-NLS1) galaxies constitute a small but interesting sample of the g-ray-loud AGN. The radio-loudest g-NLS1 known, PKS... -
Pinpointing the SMBH in NGC1052
Supermassive black holes (SMBH) are essential for the production of jets in radio-loud active galactic nuclei (AGN). Theoretical models based on Blandford & Znajek... -
S5 0716+714 VLBI K- and Q-band variability
This study aims to search for the existence of intraday variability (IDV) of BL Lac object S5 0716+714 at high radio frequencies for which the interstellar scintillation effect... -
TANAMI II. Additional sources
TANAMI is a multiwavelength program monitoring active galactic nuclei (AGN) south of -30{deg} declination including high-resolution Very Long Baseline Interferometry (VLBI)... -
The hydrogen gas outflow in 3C236
The energetic feedback that is generated by radio jets in active galactic nuclei (AGNs) has been suggested to be able to produce fast outflows of atomic hydrogen (HI) gas which... -
GOODS-N AGN VLBI detect. & radio properties
Conventional radio surveys of deep fields ordinarily have arc-second scale resolutions often insufficient to reliably separate radio emission in distant galaxies originating... -
High cadence polarization monitoring of OJ287
We present a multifrequency, dense radio monitoring program of the blazar OJ287 using the 100-m Effelsberg radio telescope. The program aims to test different binary... -
NGC1052 twin-jet VLBI images
Few active galactic nuclei (AGN) reveal double-sided jet systems. However, these systems are crucial to understand basic physical properties of extragalactic jets. We address... -
TANAMI radio galaxies I
In the framework of the TANAMI multi-wavelength and VLBI monitoring, we study the evolution of the parsec-scale radio emission in radio galaxies in the southern hemisphere and... -
TXS 2013+370 gamma-ray emitting region
The gamma-ray production mechanism and its localization in blazars are still a matter of debate. The main goal of this paper is to constrain the location of the high-energy... -
VLBI images of gamma-ray nova V407 Cygni
In 2010 March, the Large Area Telescope on board Fermi revealed a transient gamma-ray source that is positionally coincident with the optical nova in the symbiotic binary, V407... -
TANAMI radio galaxies II
This is the second paper in our series studying the evolution of parsec-scale radio emission in radio galaxies in the southern hemisphere. Following our study of the radio and... -
S5 0836+710 Ground and Space VLBI images
Detailed studies of relativistic jets in active galactic nuclei (AGN) require high-fidelity imaging at the highest possible resolution. This can be achieved using very long...
