FRB 121102 is coincident with a star forming region in its host galaxy

C. G. Bassa, S. P. Tendulkar, E. A. K. Adams +16

We present optical, near- and mid-infrared imaging of the host galaxy of FRB 121102 with the Gemini North telescope, the Hubble Space Telescope and the Spitzer Space Telescope. The…

Planar infall of CH3OH gas around Cepheus A HW2

A. Sanna, L. Moscadelli, G. Surcis +3

Aims: In order to test the nature of an (accretion) disk in the vicinity of Cepheus A HW2, we measured the three-dimensional velocity field of the CH3OH maser spots, which are proj…

Trigonometric distance and proper motions of H2O maser bowshocks in AFGL 5142

Ross A. Burns, Toshihiro Handa, Hiroshi Imai +6

We present the results of multi-epoch VLBI observations of water masers in the AGFL 5142 massive star forming region. We measure an annual parallax of mas, corr…

The Repeating Fast Radio Burst FRB 121102 as Seen on Milliarcsecond Angular Scales

B. Marcote, Z. Paragi, J. W. T. Hessels +26

The millisecond-duration radio flashes known as Fast Radio Bursts (FRBs) represent an enigmatic astrophysical phenomenon. Recently, the sub-arcsecond localization (~ 100mas precisi…

The direct localization of a fast radio burst and its host

S. Chatterjee, C. J. Law, R. S. Wharton +22

Fast radio bursts are astronomical radio flashes of unknown physical nature with durations of milliseconds. Their dispersive arrival times suggest an extragalactic origin and imply…
