Gamma-ray emission in radio galaxies under the VLBI scope -- II. The relationship between gamma-ray emission and parsec-scale jets in radio galaxies
R. Angioni, E. Ros, M. Kadler +22
Following our study of the radio and high-energy properties of -ray-emitting radio galaxies, here we investigate the kinematic and spectral properties of the parsec-scale jets o…
Gamma-ray emission in radio galaxies under the VLBI scope -- I. Parsec-scale kinematics and high-energy properties of -ray detected TANAMI radio galaxies
R. Angioni, E. Ros, M. Kadler +22
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 thei…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry - II. Additional Sources
C. Müller, M. Kadler, R. Ojha +31
TANAMI is a multiwavelength program monitoring active galactic nuclei (AGN) south of -30deg declination including high-resolution Very Long Baseline Interferometry (VLBI) imaging,…
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…
Coincidence of a high-fluence blazar outburst with a PeV-energy neutrino event
M. Kadler, F. Krauß, K. Mannheim +40
The discovery of extraterrestrial very-high-energy neutrinos by the IceCube collaboration has launched a quest for the identification of their astrophysical sources. Gamma-ray blaz…
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…
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…
The TANAMI Program
Cornelia Mueller, Matthias Kadler, Roopesh Ojha +23
TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) is a monitoring program to study the parsec-scale structures and dynamics of relativistic jets i…
