Globular cluster mass-loss in the context of multiple populations [PDF]
, 2015 Many scenarios for the origin of the chemical anomalies observed in globular clusters (GCs; i.e., multiple populations) require that GCs were much more massive at birth, up to $10-100\times$, than they are presently.

Mass to Luminosity Ratios of Some Clusters in the Large Magellanic Cloud [PDF]
Journal of Astronomy and Space Sciences, 1990 Luminosity profiles and dynamical parameters of 12 globular clusters in the Large Magellanic Cloud (SB(s)m) are obtained from the concentric aperture photoelectric photometry of 3 different aged clusters and the collected photometric data of 9 clusters ...

The Origin of the Large Magellanic Cloud Globular Cluster NGC 2005
The Astronomical Journal, 2023 The ancient Large Magellanic Cloud (LMC) globular cluster NGC 2005 has recently been reported to have an ex situ origin, thus, setting precedents that the LMC could have partially formed from smaller merged dwarf galaxies.

A Type Ia Supernova near a Globular Cluster in the Early-type Galaxy NGC 5353
The Astrophysical Journal LettersNo progenitor of a Type Ia supernova (SN Ia) is known, but in old-population early-type galaxies, one may find SNe Ia associated with globular clusters, yielding a population age and metallicity.

MOCCA code for star cluster simulations – IV. A new scenario for intermediate mass black hole formation in globular clusters [PDF]
, 2015 We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

The Globular Cluster System of the Virgo Cluster Ultradiffuse Galaxy VCC 615
The Astrophysical JournalWe use Hubble Space Telescope imaging to study the globular cluster system of the Virgo Cluster ultradiffuse galaxy (UDG) VCC 615. We select globular cluster candidates through a combination of size and color, while simultaneously rejecting contamination

CCD Photometry of the Globular Cluster NGC 4372 [PDF]
Journal of Astronomy and Space Sciences, 1994 We present a deep (B, V) color-magnitude diagram (CMD) of the Galactic globular cluster NGC 4372. According to the recent inside-out picture of Galaxy formation, this cluster is predicted to be one of the oldest globular clusters in the Galaxy.

DARK MATTER HALOS IN GALAXIES AND GLOBULAR CLUSTER POPULATIONS [PDF]
, 2014 We combine a new, comprehensive database for globular cluster populations in all types of galaxies with a new calibration of galaxy halo masses based entirely on weak lensing.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.
