Resumen
We report on the first results of an all-sky survey program to investigate the large-scale structure of the interstellar medium in the Galactic neighbourhood of our Solar System, using far-infrared IRAS data. Our work focuses mainly on the indicators of past high pressure events (supernova explosions and stellar winds). We have identified several of these objects as loop- or arc-like intensity enhancements in the far infrared, and have analyzed their individual FIR properties and their distribution on the sky.
