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...
متن کاملINTERFEROMETRIC PHASE CALIBRATION SOURCES IN THE DECLINATION RANGE 0 ◦ TO − 30 ◦ Joshua
We present a catalog of 321 compact radio sources in the declination range 0 > δ > −30. The positions of these sources have been measured with a two–dimensional rms accuracy of 35 milliarcseconds using the NRAOa Very Large Array. Each source has a peak flux density> 50 mJy at 8.4 GHz. We intend for this catalog to be used mainly for selection of phase calibration sources for radio interferomete...
متن کاملThe Identification of EGRET Sources with Flat-Spectrum Radio Sources
We present a method to assess the reliability of the identification of EGRET sources with extragalactic radio sources. We verify that EGRET is detecting the blazar class of AGN. However, many published identifications are found to be questionable. We provide a table of 42 blazars which we expect to be robust identifications of EGRET sources. This includes one previously unidentified EGRET sourc...
متن کاملThe radio flaring behaviour of GRO J 1655 − 40 : an analogy with extragalactic radio sources ?
At radio frequencies, the current evidence for the microquasar–quasar connection is based on imaging observations showing that relativistic outflows/jets are found in both classes of objects. Some microquasars also display superluminal motion, further strengthening the view that microquasars are in fact Galactic miniatures of quasars. Here we demonstrate that this connection can be extended to ...
