Physics of nonthermal radio sources

Measurement of the radiation from thermal and nonthermal radio sources

The widespread use of the internet has enabled complex instrumentation to be available remotely and made it possible for students to use facilities to which they might otherwise not have access. Internet access to radio astronomical observatories, including the 37 m radio telescope at the Massachusetts Institute of Technology Haystack Observatory, has opened up new possibilities for undergradua...

Estimating the Number of Wideband Radio Sources

In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...

MHD Simulations of Radio Galaxies Including Nonthermal Electron Transport

We report on an effort to study the connections between dynamics in simulated radio galaxy plasma flows and the properties of nonthermal electron populations carried in those flows. To do this we have introduced a new numerical scheme for electron transport that allows a much more detailed look at this problem than has been possible before. Especially when the dynamics is fully three dimensiona...
