Kilogauss magnetic field and jet dynamics in the quasar NRAO 530
Mikhail Lisakov, Svetlana Jorstad, Maciek Wielgus +12
The advancement of the Event Horizon Telescope has enabled the study of relativistic jets in active galactic nuclei down to sub-parsec linear scales even at high redshift. Quasi-si…
Mid-Infrared studies of dusty sources in the Galactic Center
Harshitha K. Bhat, Nadeen B. Sabha, Michal Zajaček +5
Mid-Infrared (MIR) images of the Galactic center show extended gas and dust features along with bright IRS sources. Some of these dust features are a part of ionized clumpy streame…
A persistent double nuclear structure in 3C 84
Junghwan Oh, Jeffrey A. Hodgson, Sascha Trippe +11
3C 84 (NGC 1275) is the radio source at the center of the Perseus Cluster and exhibits a bright radio jet. We observed the source with the Global Millimeter VLBI Array (GMVA) betwe…
Gas and stellar dynamics in Stephan's Quintet: Mapping the kinematics in a closely interacting compact galaxy group
M. Yttergren, P. Misquitta, Á. Sánchez-Monge +4
Stephan's Quintet (SQ) is a nearby compact galaxy group and a perfect laboratory for studying the process of galaxy evolution through galaxy harassment and interaction. By analysin…
Observations of the 86 GHz SiO maser sources in the Central Parsec of the Galactic Centre
A. Borkar, A. Eckart, C. Straubmeier +8
We present results of 3 mm observations of SiO maser sources in the Galactic Centre (GC) from observations with the Australia Telescope Compact Array between , along the…
Micro-arcsecond structure of Sagittarius A* revealed by high-sensitivity 86 GHz VLBI observations
Christiaan D. Brinkerink, Cornelia Müller, Heino D. Falcke +21
The compact radio source Sagittarius~A (Sgr~A)in the Galactic Center is the primary supermassive black hole candidate. General relativistic magnetohydrodynamical (GRMHD) si…
