GMRT study of X-shaped radio sources
Dharam Vir Lal, A. Pramesh Rao, Martin J. Hardcastle +5
Context. The nature of X-shaped sources is a matter of considerable debate in the literature: it has even been proposed that they provide evidence for black-hole-mergers/spin-reori…
A Global 86GHz VLBI Survey of Compact Radio Sources
Sang-Sung Lee, Andrei P. Lobanov, Thomas P. Krichbaum +5
We present results from a large 86GHz global VLBI survey of compact radio sources. The main goal of the survey is to increase by factors of 3--5 the total number of objects accessi…
IRS 13N: a new comoving group of sources at the Galactic Center
K. Muzic, R. Schoedel, A. Eckart +2
Context: The Galactic Center IRS 13E cluster is located ~3.2'' from SgrA*. It is an extremely dense stellar association containing several Wolf-Rayet and O-type stars, at least fou…
First proper motions of thin dust filaments at the Galactic Center
K. Muzic, A. Eckart, R. Schoedel +2
Context: L'-band (3.8 micron) images of the Galactic Center show a large number of thin filaments in the mini-spiral, located west of the mini-cavity and along the inner edge of th…
VLBI at the highest frequencies - AGN studied with micro-arcsecond resolution
T. P. Krichbaum, I. Agudo, U. Bach +2
Compact galactic and extragalactic radio sources can be imaged with an unsurpassed angular resolution of a few ten micro-arcseconds, adopting the observing technique of global mill…
Cosmological evolution of compact AGN at 15 GHz
Tigran Arshakian, Eduardo Ros, Anton Zensus
We study the uniformity of the distribution of compact flat-spectrum AGN on the sky and the evolution of their relativistic jets with cosmic epoch. A complete sample of compact ext…
