The development of an instrument designed to conduct balloon-borne observations in the medium energy gamma-ray region is described. Based on the Compton coincidence principle, the NASA/Goddard Advanced Compton Telescope (ACT), is intended for the study of point sources of cosmic gamma-rays in the energy range from approximately 0.5 to 30 MeV. The value of the results anticipated from the experiment are summarized in terms of constraints which may be imposed on currently viable models of gamma-ray emission from Seyfert galaxies. The results of a 21 cm neutral hydrogen survey, performed in a region of the galactic disk known as the Puppis Window, are reported. Observations were conducted on the NRAO 43 m radio telescope on an area of the Milky Way which contains much less absorbing interstellar dust and associated gas than is found in more typical regions of the Galaxy. Reports of optical spiral tracers at distances up to 8 kcp from the Sun make this area of the galactic disk ideal for the comparison of optical and radio data. Correlations of specific HI features with optical spiral tracers are discussed, along with the corresponding implications regarding the spiral structure in this quadrant of the Galaxy. Finally, the association of the young pulsar PSRO740-28 with an HI shell in Puppis is established, and evidence pointing towards its possible origin in a second-generation supernova event is discussed.
