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

=1995A&AS..110..269W (SIMBAD/NED Reference)
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.

II. Optically detected galaxies in the region 180 <= l <~ 240

=1996A&AS..117....1S (SIMBAD/NED BibCode)
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.

III. A survey for obscured galaxies in the region 120<l<130,-10<b<+10
Lercher G., Kerber F., Weinberger R.
=1996A&AS..117..369L (SIMBAD/NED BibCode)
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.

IV. An optical survey for galaxies in the region 130<l<180, -5<b<+5

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.

V. An optical survey for hidden galaxies in the region 90<=l<=110, -10<=b<=+10
Seeberger R., Saurer W.
Astron. Astrophys. Suppl. Ser. 127, 101 (1998)
=1998A&AS..127..101S (SIMBAD/NED BibCode)
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}).
