Penetrating the "zone of avoidance". I. A compilation of optically identified extragalactic objects within |b| = < 5deg.

We present a compilation of hopefully all published galaxies and quasars that were ever optically identified within |b|=<5deg. We present 2304 objects and list (and discuss), in addition to their (often considerably improved) coordinates, the best available morphological type, optical maximum diameters in the red, up-to-date heliocentric radial velocities, references to the papers where a specific object was first optically identified and results of cross-checks with the IRAS point source catalogue.

Penetrating the "zone of avoidance". II. Optically detected galaxies in the region 180 <= l <~ 240

We have carried out a systematic search for galaxies in the galactic plane in a ten degree wide strip (-5deg<=b<=+5deg). In an area of 300 square degrees between l=180deg and l=210deg, 755 galaxies have been detected on Palomar red- sensitive prints. The smallest galaxies show diameters of 0.1mm corresponding to 6.7". We extended our survey to {delta}=-27deg i.e. l=~247deg to check our catalogue for completeness by comparing it with the Saito et al. (1990, 1991) catalogues of galaxies and present 334 new galaxy candidates at l>=210deg. An asymmetry with respect to the galactic equator is obvious. By assuming the 60{mu} and 100{mu} sky flux density to be a rough measure of the total interstellar galactic extinction, and comparing them with the surface densities of the galaxies, we detected one possible galaxy cluster candidate at (l,b)=~(181.5deg+3.5deg), a concentration of galaxies at (l,b)=~(195deg+4.5deg), and confirmed three other galaxy concentrations. Finally, we argue that the red-sensitive surveys (ESO R; POSS II-R, POSS II-IR) are the best suitable material for galaxy searches in the zone of avoidance.

Penetrating the 'zone of avoidance': III. A survey for obscured galaxies in the region 120<l<130,-10<b<+10

As the third part in a series of papers on galaxies in the "zone of avoidance" (ZOA) of the Milky Way we present a compilation of 1161 galaxies discovered during a systematic search on Palomar Observatory Sky Survey (POSS) red-sensitive prints. The region searched comprises 200 square degrees, at 120deg<=l<=130deg, -10deg<=b<=+10deg. In addition to galactic, equatorial and rectangular coordinates, we list maximum and minimum optical diameters derived from both the red- and blue-sensitive prints, could assign a morphological type to some of the objects and made cross-checks with the IRAS PSC and several radio catalogues. A test for completeness suggests, that our catalogue should be complete down to a limiting galaxy-diameter of 0.35'. An asymmetric distribution of the galaxies with respect to the galactic equator was found and is discussed by comparing it with the locations of optically visible dust clouds and/or the distribution of IR-emitting dust material. A comparison between the distribution of the galaxies and the 100{mu} IRAS intensity maps led to the identification of four possible clusterings. As a byproduct of our galaxy search, two new planetary nebulae, nebulous stars at the position of a strong cold IRAS point source, and a nearby dwarf irregular galaxy could be detected.

As the fourth part in a series of papers on galaxies in the "zone of avoidance" (ZOA) of the Milky Way we present a compilation of 1067 galaxies discovered during a systematic search on Palomar Observatory Sky Survey I (POSSI) red-sensitive prints. The region searched comprises 500 square degrees, at 130{deg}<=l<=180{deg}, -5{deg}<=b<=+5{deg}. In addition to galactic and equatorial coordinates, we list maximum and minimum optical diameters derived from both the red- and blue-sensitive prints and made cross checks with the IRAS PSC catalogue. An asymmetric distribution of the galaxies with respect to the galactic equator is found and is compared to the locations of optically visible dust clouds and/or the distribution of IR-emitting dust material. There is a pronounced bridge of galaxies across the galactic plane at l=~160{deg} which will be discussed according to recent results on the extension of the Pisces-Perseus supercluster.

Penetrating the "zone of avoidance" V. An optical survey for hidden galaxies in the region 90<=l<=110, -10<=b<=+10

As the fifth part in our series of papers on galaxies in the "zone of avoidance" (ZOA) of the Milky Way we present 1346 new galaxy candidates discovered during a systematic search on Palomar Observatory Sky Survey (POSSI-E) red-sensitive prints. The region searched comprises 400 square degrees at 90{deg}<=l<=110{deg}, -10{deg}<=b<=+10{deg}. We list galactic and equatorial coordinates, maximum optical diameters and diameters of the core, if visible, both for the red- and blue-sensitive POSS prints. An asymmetric distribution of the galaxies with respect to the galactic equator is found and can most probably be attributed to the galactic warp. We also present radial velocities for 14 galaxies measured for the first time which are located in the region where a branch of the Pisces Perseus Supercluster is approaching the ZOA from the south (l=~90{deg}, b=~-10{deg}).
