galaxies: interactionsgalaxies: star clusters: generalThe ACS and NICMOS have been used to obtain new HST images of NGC 4038/4039 ("The Antennae"). These new observations allow us to better differentiate compact star clusters from individual stars, based on both size and color. We use this ...
Now of particular interest to us today is that the same type of radiation has been observed in places where galaxies have collided.And in those same areas, we’ve also observed a high rate of new star formation.So not surprisingly, we’ve had a theory that colliding galaxies caused the ne...
galaxies: individual: Antennaegalaxies: ISMradio lines: ISMinfrared: ISMWe present an analysis of super-giant molecular complexes (SGMCs) in the overlap region of the Antennae galaxy merger, based on ALMA CO(3−2) interferometry and VLT/SINFONI imaging spectroscopy of H2 1−0 S(1) at...

The high spatial resolution of Chandra allows us to ...
Our aim is to investigate whether similar sequences can be found in other nearby galaxies.Methods: This is done using data of cluster properties from the literature.Results: For the extragalactic young stellar clusters we detect an overall trend in the cluster-density scaling that is comparable ...
VLBI Earth-based antennae are commonly utilized in radio astronomy to present high-resolution images of celestial objects originating from space radiation signals, such as galaxies, planets, and nebulas, among others [1,2,3]. The VLBI is essentially a geometrical technique, where a set of Earth...
