In Figure 2, we show the spectra of the optical counterparts to 85 of 97 observed X-ray/radio sources. ... Positional information for all 85 sources for which we announce identifications herein are given in Table 3, including information from WGACAT, the PMN and Green Bank surveys, the NVSS and our ATCA survey. ... Of the 85 newly identified sources, 59 are FSRQs, and 22 are BL Lacs. ...

... The stars examined here were primarily culled from two lists of X--ray sources in Orion. ... The second region is two degrees in extent east--west and ten degrees north--south with Orionis being near the northern edge. ... In the end, two main regions were chosen for monitoring: stars near Orionis and stars northwest of the belt of Orion. ... The PSPC identified 22 sources within 15 of Orionis in addition to the sources listed in Table 1 , giving a total of 85 X--ray sources in the Orionis region. ...

... 105Lawrence+ Nearly 1000 sources from the 5 GHz MIT-Green Bank (MG) survey have been observed with the VLA. ... About 1000 sources, selected as described in IIa from a prelimenary version of the MIT-GB I catalog, have been observed with VLA. ... About 20 sources observed at the VLA are within the MG sky area and above the 106 mJy completeness limit, even allowing for the large flux-density errors in the preliminary list, but do not appear in the MG catalog. ... 1 Source name in IAU B1950.0 format. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

Spitzer Space Telescope mid-infrared spectroscopy has been obtained for 15 carbon-rich protoplanetary nebulae (PPNe) in the Large Magellanic Cloud (LMC) and for two other such stars in the Small Magellanic Cloud (SMC). Of these 17 PPNe, the unidentified 21 ѕ®m feature is strong in 7 spectra, weak in 2 spectra, and very weak or questionable in 4 spectra. ... The remaining two objects show typical carbon-rich PPNe spectra with no 21 ѕ®m features. ...

Introduction Gigahertz peaked spectrum (GPS) sources have a sharply peaked radio spectrum and possess one or more compact components that are physically small (!100pc), highly luminous (P ? ... The incidence of extended structure in GPS sources is small, at around 20% of all the objects examined (O'dea et al, 1991, ApJ, 380, 66). ... Absorption Processes It has long been thought that the low frequency spectral turnover characteristic of GPS sources is because of synchrotron self­absorption (SSA). ...
