[en] Raw and maximum entropy restored images of the quasar pair (gravitational lens candidate) 2345 + 007 A and B are presented. Restorations are performed using an implementation of the Gull-Skilling MEMSYS-3 package of maximum entropy method subroutines designed to achieve subpixel resolution in certain data regimes. Extensive simulations of the data imply that it is possible to detect structure in the restored images down to the 0.4 inch level. Using this method, it is qualitatively confirmed that component B is resolved and, at least at visual and red wavelengths, elongated in a direction almost perpendicular to the line joining A and B. Evidence is found for a color difference and variation in the magnitude difference between the two components. These data, in conjunction with recent spectroscopic results, more likely favor the multiple quasar rather than gravitational lens interpretation of the objects. 18 refs

[en] A heuristic model is proposed for the origin of the cosmic submillimeter background (SMB) reported by the Nagoya-Berkeley collaboration (Matsumoto et al., 1988). In this model, the SMB is interpreted as a direct signature of an epoch of (initial) galaxy formation at z of about 10-15. The sources of the SMB are proposed to be dust-shrouded starburst protogalaxies, similar to the low-redshift extremely luminous FIR IRAS galaxies. The model may also account for a large part of the diffuse soft X-ray background. 170 refs

[en] This paper reports on the discovery of a compact, unresolved infrared nucleus, coincident with the radio core, in the prototypical powerful radio galaxy Cygnus A (3C 405). The infrared colors and magnitudes of the nucleus can be explained as a highly reddened extension of the radio continuum. The implied restframe extinction is A(V) equal to about 50 + or - 30 magnitudes. The extinction-corrected luminosity of the object is in the quasar range. This discovery gives some support to the unification models for quasars and powerful radio galaxies. 35 refs
