Abstract:
We update the Small Magellanic Cloud (SMC), Bridge and Large
Magellanic Cloud (LMC) catalogues of extended objects that were
constructed by members of our group from 1995 to 2000. In addition to
the rich subsequent literature for the previous classes, we now also
include HI shells and supershells. A total of 9305 objects were
cross-identified, while our previous catalogues amounted to 7900
entries, an increase of ∼12 per cent. We present the results in
subcatalogues containing 1445 emission nebulae, 3740 star clusters,
3326 associations and 794 HI shells and supershells. Angular and
apparent size distributions of the extended objects are analysed. We
conclude that the objects, in general, appear to respond to tidal
effects arising from the LMC, SMC and Bridge. Number-density profiles
extracted along directions parallel and perpendicular to the LMC bar,
can be described by two exponential-discs. A single exponential-disc
fits the equivalent SMC profiles. Interestingly, when angular-averaged
number-densities of most of the extended objects are considered, the
profiles of both Clouds do not follow an exponential-disc. Rather,
they are best described by a tidally truncated, core/halo profile,
despite the fact that the Clouds are clearly disturbed discs. On the
other hand, the older star clusters taken isolately, distribute as an
exponential disc. The present catalogue is an important tool for the
unambiguous identification of previous objects in current CCD surveys
and to establish new findings.
