Rotating and infalling motion around the high-mass young stellar object Cepheus A-HW2 observed with the methanol maser at 6.7 GHz
K. Sugiyama, K. Fujisawa, A. Doi +9
We have measured the internal proper motions of the 6.7 GHz methanol masers associated with Cepheus A (Cep A) HW2 using Very Long Baseline Interferometery (VLBI) observations. We c…
Observations of 6.7 GHz Methanol Masers with EAVN I: VLBI Images of the first Epoch of Observations
Kenta Fujisawa, Koichiro Sugiyama, Kazuhito Motogi +26
Very long baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motions of the maser spots and therefore study the gas mo…
X-ray and Radio Follow-up Observations of High-Redshift Blazar Candidates in the Fermi-LAT Unassociated Source Population
Y. Takahashi, J. Kataoka, K. Niinuma +6
We report on the results of X-ray and radio follow-up observations of two GeV gamma-ray sources 2FGL J0923.5+1508 and 2FGL J1502.1+5548, selected as candidates for high-redshift bl…
