IFS and IR observations of star clusters in the Antennae by Mengel, S, Lehnert, MD, Thatte, N, Genzel, R

“…Over the past decade, it has become clear that interaction induced formation of compact young star clusters is a ubiquitous pheonomenon, and the understanding of this process is thought to also shed light on galaxy evolution in general, because these young clusters are widely believed to be the progenitors of a part of the globular cluster systems seen in local elliptical galaxies. …”

“…The large populations of young star clusters observed in interacting galaxies like NGC4038 4039 ("The Antennae") are widely believed to be the progenitors of part of the globular cluster systems seen in local elliptical galaxies. …”

Intense Star Cluster Formation: Stellar Masses, the Mass Function, and the Fundamental Mass Scale by Christopher D. Matzner

“…Within the birth environment of a massive globular cluster, the combination of a luminous young stellar population and a high column density induces a state in which the thermal optical depth and radiation pressure are both appreciable. …”

The Low Frequency Perspective on Fast Radio Bursts by Maura Pilia

“…The latest, most important discoveries include: periodicity, both at the days level in repeaters and at the millisecond level in apparently non-repeating sources; the detection of an FRB-like burst from a galactic magnetar; and the localisation of an FRB inside a globular cluster in a nearby galaxy. The systematic study of the population at low frequencies is important for the characterisation of the environment surrounding the FRBs and, at a global level, to understand the environment of the local universe. …”

The Multiple Extended Tidal Tails of NGC 288 by Carl J. Grillmair

“…Using photometry and proper motions from Pan-STARRS, DECaLS, and Gaia Data Release 3, we detect a ∼35°–70° long trailing stellar debris stream associated with the globular cluster NGC 288. The trajectory of the trailing tail is not well matched by a model stream evolved in a static Galactic potential, but is reasonably well matched by a stream modeled in a potential that incorporates a massive, infalling Large Magellanic Cloud. …”

A hierarchical triple star system in M4 by Rasio, F

“…The radio millisecond pulsar PSR B1620-26 is part of an extraordinary triple star system in the globular cluster M4. The inner companion to the neutron star is thought to be a white dwarf of mass m(1) similar or equal to 0.3 M-circle dot in an orbit of period similar or equal to 0.5 yr. …”

Black hole disks in galactic nuclei by Szölgyén, A, Kocsis, B

Probing the Sagittarius stream with blue horizontal branch stars by Clewley, L, Jarvis, M

“…Three of our BHB stars in the direction of the globular cluster Palomar (Pal) 5 appear to be in an overdensity but are in the foreground of Pal 5. …”

Locations of Peculiar Supernovae as a Diagnostic of Their Origins by Yuan, F, Kobayashi, C, Schmidt, B, Podsiadlowski, P, Sim, SA, Scalzo, R

“…Because photometric upper limits exist for globular clusters for some members of the class, a production mechanism related to the dense environment of globular clusters is not favoured for the calcium-rich events. …”

Optimizing Urban-Scale Evacuation Strategies Through Disaster Victim Aggregation Modification by Reza Asriandi Ekaputra, Seong-Hoon Kee, Jurng-Jae Yee

“…The Ensemble Clustering method combines the K-Means clustering strengths in dividing disaster victim distribution into globular cluster distribution. DBSCAN supports it as a robust outlier identification for disaggregating the irrelevant member as an individual. …”

Utilizing Voronoi Tessellations to Determine Radial Density Profiles by Veronika Dornan, William E. Harris

“…Finally, the Voronoi-based method was applied to two observed globular cluster systems around brightest cluster galaxies ESO 444-G046 and 2MASX J13272961-3123237 and the results were compared to previous results for these galaxies obtained with the annulus-based method. …”
