The population of SNe/SNRs in the starburst galaxy Arp 220. A self-consistent analysis of 20 years of VLBI monitoring
E. Varenius, J. E. Conway, F. Batejat +6
The nearby ultra-luminous infrared galaxy (ULIRG) Arp 220 is an excellent laboratory for studies of extreme astrophysical environments. For 20 years, Very Long Baseline Interferome…
Rapid variability of the compact radio sources in Arp220. Evidence for a population of microblazars?
F. Batejat, J. E. Conway, A. Rushton +3
Context. The two nuclei of the starburst galaxy Arp220 contain multiple compact radio sources previously identified as radio supernovae or supernova remnants. Aims. In order to sea…
SiO masers in TX Cam: Simultaneous VLBA observations of two 43 GHz masers at four epochs
Jiyune Yi, R. S. Booth, J. E. Conway +1
We present the results of simultaneous high resolution observations of v=1 and v=2, J=1-0 SiO masers toward TX Cam at four epochs covering a stellar cycle. Near maser maximum (Epoc…
The Relative Spatial Distribution of SiO Masers in AGB Stars at 43 and 86 GHz
J. -F. Desmurs, R. Soria-Ruiz, F. Colomer +6
We present the first VLBI images of SiO masers in the circumstellar envelope of an S-type star obtained with the newly developed capabilities of the Very Long Baseline Array (VLBA)…
VLBA Continuum Observations of NGC 4258: Constraints on an Advection-Dominated Accretion Flow
J. R. Herrnstein, L. J. Greenhill, J. M. Moran +4
We report a 3 sigma upper limit of 220 microJanskys on any 22-GHz continuum emission coincident with the central engine in NGC 4258. If NGC 4258 is powered by an advection-dominate…
Deceleration in the Expansion of SN1993J
J. M. Marcaide, A. Alberdi, E. Ros +13
A rarity among supernova, SN 1993J in M81 can be studied with high spatial resolution. Its radio power and distance permit VLBI observations to monitor the expansion of its angular…
