ALMA Science Verification Data: Millimeter Continuum Polarimetry of the Bright Radio Quasar 3C 286
H. Nagai, K. Nakanishi, R. Paladino +6
We present full-polarization observations of the compact, steep-spectrum radio quasar 3C~286 made with the ALMA at 1.3~mm. These are the first full-polarization ALMA observations,…
Discovery of a wandering radio jet base after a large X-ray flare in the blazar Markarian 421
K. Niinuma, M. Kino, A. Doi +3
We investigate the location of the radio jet bases ("radio cores") of blazars in radio images, and their stationarity by means of dense very long baseline interferometry (VLBI) obs…
230 GHz VLBI observations of M87: event-horizon-scale structure at the enhanced very-high-energy -ray state in 2012
Kazunori Akiyama, Ru-Sen Lu, Vincent L. Fish +45
We report on 230 GHz (1.3 mm) VLBI observations of M87 with the Event Horizon Telescope using antennas on Mauna Kea in Hawaii, Mt. Graham in Arizona and Cedar Flat in California. F…
The off-axis jet structure in Mrk 501 at mm-wavelengths
Shoko Koyama, Motoki Kino, Marcello Giroletti +10
We present results from 43 GHz (VLBA, six epochs from 2012.2 to 2013.2) and 86 GHz (GMVA, one epoch in 2012.4) observations toward the basis of the jet in the TeV Blazar Mrk 501. T…
Continuing EVN monitoring of HST-1 in the jet of M87
Kazuhiro Hada, Marcello Giroletti, Gabriele Giovannini +9
The relativistic jet in M87 offers a unique opportunity for understanding the detailed jet structure and emission processes due to its proximity. In particular, the peculiar jet re…
The Nuclear Structure of 3C84 with Space VLBI (RadioAstron) Observations
Gabriele Giovannini, Monica Orienti, Tuomas Savolainen +15
The radio galaxy 3C84 is a representative of gamma-ray-bright misaligned active galactic nuclei (AGN) and one of the best laboratories to study the radio properties of subparsec sc…
