In the past years, high angular resolution observations have revealed that circumstellar discs appear in a variety of shapes with diverse substructures being ubiquitous. This has given rise to question whether these are triggered by planet-disc interactions. Besides direct imaging, one most promising methods distinguish between different disc shaping mechanisms is study kinematics gas disc. par...

The Molecular Ridge in the LMC extends several kiloparsecs south from 30 Doradus, and it contains ∼30% of molecular gas entire galaxy. However, southern end is quiescent—it almost no massive star formation, which a dramatic decrease very active massive-star-forming regions N159, N160. We present new Atacama Large Millimeter/submillimeter Array Pathfinder Experiment observations at resolution as...

We report mapping observations of the 12CO J = 3 → 2, 4 → 3, 6 → 5, and 7 → 6 transitions and the C i P1 →P0 (C i) 492 GHz transition toward the central 40′′×40′′ region of the Circinus galaxy, using the Atacama Pathfinder EXperiment (APEX) telescope. We also detected 13CO J = 3 → 2 at the central position of Circinus. These observations are to date the highest CO transitions reported in Circin...

Stephan's Quintet (SQ) is a nearby compact galaxy group and perfect laboratory for studying the process of evolution through harassment interaction. By analysing kinematics SQ we aim to provide an increased understanding group, history interactions, their cause effect, details regarding physical processes occurring as galaxies interact. We have studied ionised gas stellar using Large Binocular ...
