Their (nearly) ubiquitous presence is the reason behind the term “the bubbling galactic disk” ( Churchwell et al. Some of the structures resemble envelopes and are known as shells or bubbles. ![]() The interstellar medium (ISM) in the Galaxy shows a rich variety of structures, including clumps, filaments and dense sheets. Key words: ISM: bubbles / ISM: clouds / HII regions / ISM: supernova remnants Interstellar material, suggesting that they are an important mechanism for star We propose that suchĬollisions increase the probability of further star formation, probably by squeezing the We found that both infrared bubbles N115 and N116+117 areĪssociated with the collisions of larger and older bubbles. Than a million years) infrared bubble lies at the position of the collision.Ĭonclusions. They are both formed by two largeĬolliding bubbles with radii around 20–30 pc and ages of a few million years. Lying at different distances, but look similar. Two large HI bubbles, which we discovered in the HI data. The second, the foreground system, includes the infrared bubble N115 and System, is formed by large structures G053.9+0.2 and SNR G054.4-0.3 and the infraredīubble N116+117. We identified two systems of bubbles: the first, the background Size, expansion velocity, mass, original density of the maternal cloud, age, and energy The IR images and applied them to the HI and CO data. We manually constructed masks based on the appearance of the bubbles in To find bubbles in HI (Very Large Array Galactic Plane Survey)Īnd CO data (Galactic Ring Survey), we used the images from the Galactic Legacy Infrared Properties of the bubbles, we also look into their ambient environment to understand their With atomic, molecular and ionized gas in this region. We compare infrared observations of bubbles N115, N116 and N117 Objects are commonly associated with these structures.Īims. Radiation of massive stars, or supernova explosions. Their progenitors are stellar winds, intense With diameters of a few to tens of parsecs.
