VGOS VLBI Intensives between MACGO12M and WETTZ13S for the rapid determination of UT1-UTC
Matthias Schartner, Leonid Petrov, Christian Plötz +3
In this work, we present a status update and results of the designated research and development VLBI Intensive program VGOS-INT-S, observed between MACGO12M and WETTZ13S for the ra…
The TANAMI Multiwavelength Program: Dynamic SEDs of Southern Blazars
Felicia Krauß, Joern Wilms, Matthias Kadler +32
Simultaneous broadband spectral and temporal studies of blazars are an important tool for investigating active galactic nuclei (AGN) jet physics. We study the spectral evolution be…
Radio and Gamma-ray Properties of Extragalactic Jets from the TANAMI Sample
M. Böck, M. Kadler, C. Müller +28
Using high-resolution radio imaging with VLBI techniques, the TANAMI program has been observing the parsec-scale radio jets of southern (declination south of -30°) gamma-ray bright…
The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS 2004-447 II. The Radio View
R. Schulz, A. Kreikenbohm, M. Kadler +20
Gamma-ray detected radio-loud narrow-line Seyfert 1 (g-NLS1) galaxies constitute a small but interesting sample of the gamma-ray loud AGN. The radio-loudest g-NLS1 known, PKS 2004-…
The Gamma-Ray Emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy PKS 2004-447 I. The X-Ray View
Annika Kreikenbohm, Robert Schulz, Matthias Kadler +11
As part of the TANAMI multiwavelength progam, we discuss new X-ray observations of the -ray and radio-loud Narrow Line Seyfert galaxy (-NLS1) PKS 2004-447. The active galaxy…
TANAMI monitoring of Centaurus A: The complex dynamics in the inner parsec of an extragalactic jet
C. Müller, M. Kadler, R. Ojha +24
Centaurus A is the closest radio-loud active galaxy. Very Long Baseline Interferometry (VLBI) enables us to study the jet-counterjet system on milliarcsecond (mas) scales, providin…
TANAMI Blazars in the IceCube PeV Neutrino Fields
F. Krauß, M. Kadler, K. Mannheim +39
The IceCube Collaboration has announced the discovery of a neutrino flux in excess of the atmospheric background. Due to the steeply falling atmospheric background spectrum, events…
The unusual multiwavelength properties of the gamma-ray source PMNJ1603-4904
Cornelia Müller, M. Kadler, R. Ojha +27
We investigate the nature and classification of PMNJ1603-4904, a bright radio source close to the Galactic plane, which is associated with one of the brightest hard-spectrum gamma-…
Dual-frequency VLBI study of Centaurus A on sub-parsec scales
Cornelia Müller, M. Kadler, R. Ojha +16
Centaurus A is the closest active galactic nucleus. High resolution imaging using Very Long Baseline Interferometry (VLBI) enables us to study the spectral and kinematic behavior o…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry I. First-Epoch 8.4 GHz Images
Roopesh Ojha, Matthias Kadler, Moritz Böck +24
We introduce the TANAMI program (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) which is monitoring an initial sample of 43 extragalactic jets located…
