Multiple populations in globular clusters. Lessons learned from the Milky Way globular clusters

open access: yes, 2012
Recent progress in studies of globular clusters has shown that they are not simple stellar populations, being rather made of multiple generations. Evidence stems both from photometry and spectroscopy.

High resolution imaging of the early-type galaxy NGC 1380: an insight into the nature of extended extragalactic star clusters [PDF]

open access: yes, 2007
NGC 1380 is a lenticular galaxy located near the centre of the Fornax Cluster northeast of NGC 1399. The globular cluster system of this galaxy was previously studied only from the ground.

Modeling Dense Star Clusters in the Milky Way and Beyond with the CMC Cluster Catalog [PDF]

open access: yesAstrophysical Journal Supplement Series, 2019
We present a set of 148 independent N-body simulations of globular clusters (GCs) computed using the code CMC (Cluster Monte Carlo). At an age of ∼10–13 Gyr, the resulting models cover nearly the full range of cluster properties exhibited by the Milky ...

Star-Forming Galaxies at z~2 and the Formation of the Metal-Rich Globular Cluster Population

open access: yes, 2010
We examine whether the super star-forming clumps (R~1-3 kpc; M~10^8-10^9.5 Msun) now known to be a key component of star-forming galaxies at z~2 could be the formation sites of the locally observed old globular cluster population.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Black holes: The next generation—repeated mergers in dense star clusters and their gravitational-wave properties [PDF]

open access: yesPhysical Review D, 2019
When two black holes merge in a dense star cluster, they form a new black hole with a well-defined mass and spin. If that "second-generation" black hole remains in the cluster, it will continue to participate in dynamical encounters, form binaries, and ...

Star and Globular Cluster Formation in Mergers [PDF]

open access: yesSymposium - International Astronomical Union, 1996
The high burst strengths and star formation efficiencies found with spectrophotmetric and chemical evolutionary synthesis for mergers of gas-rich spirals led us to expect the formation of a secondary population of globular clusters (GC) with enhanced metallicity (F. – v. A. & Gerhard 1994, A&A 285, 751 u.775).

Binary Stars and Globular Cluster Dynamics [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractIn this brief proceedings article I summarize the review talk I gave at the IAU 246 meeting in Capri, Italy, glossing over the well-known results from the literature, but paying particular attention to new, previously unpublished material. This new material includes a careful comparison of the apparently contradictory results of two independent

Circulating histones as clinical biomarkers in critically ill conditions

open access: yesFEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.
