Point Source C-Band Mueller Matrices for the Green Bank Telescope
Paul Fallon, Derck P Smits, Tapasi Ghosh +2
C-Band Mueller matrices for the Green Bank Telescope are presented here which enable on-sky Stokes parameters for point sources at the beam center to be determined. Standard calibr…
An nl-model with radiative transfer for hydrogen recombination line masers
Andri Prozesky, Derck P. Smits
Atomic hydrogen masers occur in recombination plasmas in sufficiently dense HII regions. These hydrogen recombination line (HRL) masers have been observed in a handful of objects t…
The influence of continuum radiation fields on hydrogen radio recombination lines
Andri Prozesky, Derck P. Smits
Calculations of hydrogen departure coefficients using a model with the angular momentum quantum levels resolved that includes the effects of external radiation fields are presented…
A Masing Event in NGC6334I: Contemporaneous Flaring of Hydroxyl, Methanol and Water Masers
G. C. MacLeod, D. P. Smits, S. Goedhart +7
As a product of the maser monitoring program with the 26m telescope of the Hartebeesthoek Radio Astronomy Observatory (HartRAO), we present an unprecedented, contemporaneous flarin…
The Extraordinary Outburst in the Massive Protostellar System NGC6334I-MM1: Emergence of Strong 6.7 GHz Methanol Masers
T. R. Hunter, C. L. Brogan, G. C. MacLeod +7
We report the first sub-arcsecond VLA imaging of 6 GHz continuum, methanol maser, and excited-state hydroxyl maser emission toward the massive protostellar cluster NGC6334I followi…
Highly absorbed X-ray binaries in the Small Magellanic Cloud
G. Novara, N. La Palombara, S. Mereghetti +12
Many of the high mass X-ray binaries (HMXRBs) discovered in recent years in our Galaxy are characterized by a high absorption, most likely intrinsic to the system, which hampers th…
