[en] The discovery is reported of an apparently normal galaxy at z = 1.018, designated G0333 + 3208, found during a long-slit search for faint emission-line objects. One strong emission line has been detected in the wavelength range 3800-8500 A, which is attributed to 0 II forbidden 3727 A. The object is an about 24 mag galaxy with a relatively flat optical spectrum. There are no morphological or spectroscopic signs of an active nucleus in the object, or in its vicinity, and no radio flux from the object down to 200 micro-Jy rms at lambda = 20 cm. From the emission-line flux, assuming photoionization by young stars and a normal IMF, a star formation rate of about 3.5/sq h solar mass/yr (for omega0 = 1). This object would thus be among the most distant of normal galaxies now known. It may be representative of the faint blue or flat-spectrum population, which dominates deep galaxy counts. 22 refs

[en] A possible optical counterpart of the intergalactic H I cloud in the Virgo Cluster, discovered by Giovanelli and Haynes, is reported. It is a blue, 17 mag, irregular galaxy, and it is located near the peak of the H I emission. No other optical objects which can be obviously associated with the cloud are found in the area from which the H I emission was detected, and no extended, low surface brightness counterpart is seen in these data. If the irregular galaxy is really associated with the H I cloud, the overall properties of the system would be similar to those of a number of other known gas-rich dwarf galaxies. However, the system has an unusually large hydrogen to light ratio, and a large spatial extent, and it could be dynamically young. Optical spectroscopy is needed in order to establish whether the proposed optical counterpart is indeed correct, and if so, to determine the stage of its chemical evolution. 33 refs

[en] This is a preliminary report on surface photometry of the major fraction of known globular clusters, to see which of them show the signs of a collapsed core. More than 20 examples, or one-fifth of the total, are found. Core classifications are given for all clusters examined. The fraction of collapsed-core clusters may be an index of how long a cluster takes to reexpand after collapse. 21 references

[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] An optical identification candidate for the recently discovered 1.558 ms pulsar 1937 + 214 is presented. The source is a 20th mag red object, undetectable on the Palomar Sky Survey prints. Finding charts and offsets from nearby stars are given. (U.K.)

[en] The results are presented of long-slit CCD spectroscopy on 39 objects and four close companions from the University of Michgan objective-prism survey lists. Twelve of them are quasars with redshifts ranging from 0.326 to 2.852, and an additional 12 objects (including companions) are Seyferts or active galaxies ranging in redshift from 0.0365 to 0.227. UM 443 may be a broad absorption-line quasar. UM 565 is a star with a puzzling spectrum. Spectra are presented for a total of 25 objects. 17 refs

[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] About 90,000 IRAS point sources have been used as disk tracers in order to explore the possibility of warp in the Galactic stellar disk. The results imply that the Galactic stellar disk is warped at large radii in a way similar to the H-I layer, and that the warp is an important characteristic of the Galaxy as a whole. It is suggested that the warp may be a long-lasting phenomenon, possibly caused by asymmetries of the mass distribution in the outer regions of the Galactic dark halo. 56 refs

[en] We have measured the metric size function eta(r) defined by Petrosian on a limited sample of luminous distant galaxies, up to a redshift of 1.175. Although our investigation has a preliminary character, we find some evidence for the evolution of elliptical galaxies. Using the Ostriker-Hausman theoretical models, we place some constraints on the rates of dynamical evolution

[en] The results of long-slit CCD spectroscopy on 37 objects from the Parkes 2700 MHz survey are presented, with data for an additional two companion objects. Eight of the objects are quasars, six more are AGNs, and five more are radio galaxies. Seventeen of the objects observed are stars and, thus, probable misidentifications. Three objects show featureless spectra and are identified as possible BL Lac objects. Spectra are presented for a total of 20 objects. 20 refs
