Non-local radiative transfer of SiO masers in Miras
, 2012 Context. To properly understand the propagation of SiO masers within the shocked region of the circumstellar envelope of asymptotic giant branch stars, non-local radiative transfer calculations are required. Aims.

, 2011 My PhD research focuses on the maser emission which occurs in different regions of the circumstellar envelopes (CSEs) of evolved stars and can be studied at high angular resolution using radio interferometers.

The discrete nature of circumstellar OH maser emission
The Astronomical Journal, 1990 The Arecibo radio telescope was used to obtain high-resolution, high-SNR 1612-MHz observations of seven circumstellar OH maser sources. Each spectrum displays the double-peaked emission line profile characteristics of an expanding shell. The jaggedness of the spectra, which varies from source to source, is consistent with statistical fluctuations in ...

Circumstellar SiO Masers in the Bulge Asymmetries and Dynamical Evolution Survey
, 2019 The Bulge Asymmetries and Dynamical Evolution (BAaDE) project aims to explore the complex structure of the inner Galaxy and Galactic Bulge, by using the 43 GHz receivers at the Karl G. Jansky Very Large Array (VLA) and the 86 GHz receivers at the Atacama

Continuum Emission Associated with 6.7-GHz Methanol Masers
, 1996 We have used the Australia Telescope Compact Array (ATCA) to search for continuum emission toward three strong 6.7-GHz methanol maser sources. For two of the sources, G 339.88 - 1.26 and NGC 6334F (G 351.42 + 0.64), we detect continuum emission closely ...

FG3: spatial and frequency modeling of circumstellar masers
, 2007 We have developed a computer program (called "FG3") that is useful to model images of spectral line emission. We have applied it successfully to the study of maser emission in the circumstellar envelopes of late-type stars.

, 2008 Context. Methanol masers are often found in linear distributions, and it has been hypothesized that these masers trace circumstellar accretion disks around young massive stars.
