The FAST Globular Cluster Pulsar Survey (GC FANS)
The Astrophysical Journal Supplement SeriesBy 2025 January, 60 pulsars were discovered by the Five-hundred-meter Aperture Spherical radio Telescope globular cluster (GC) pulsar survey (GC FANS), with spin periods spanning 1.98–3960.72 ms. Of these, 55 are millisecond pulsars (MSPs; P

Revisiting the Globular Cluster Systems of NGC 3258 and NGC 3268
Galaxies, 2017 We present a photometric study of NGC 3258 and NGC 3268 globular cluster systems (GCSs) with a wider spatial coverage than previous works. This allowed us to determine the extension of both GCSs, and obtain new values for their populations.

Extragalactic globular clusters. II - The M31 globular cluster system
The Astrophysical Journal, 1991 Metallicities for 150 globular clusters associated with M31 are derived using the strengths of six absorption features in the cluster-integrated spectra. The properties of the M31 cluster system are very similar to those of the Galactic system. No dependence of metallicity on cluster luminosity is found.

New Directions for Adult and Continuing Education, EarlyView.ABSTRACT This article explores how artificial intelligence (AI) is reshaping scholarly research and writing for faculty in higher education. As AI becomes increasingly integrated into academic workflows, it offers opportunities to enhance efficiency, exchange ideas, and foster creativity, while also raising critical questions about authorship ...

The Globular Clusters and Halo of M31 [PDF]
Publications of the Astronomical Society of the Pacific, 1998 The results of two studies of M31's globular cluster system are presented. One study used deep V- and I-band images of 24 M31 globular clusters taken with CFHT's HRCam. This data is the best available ground-based data for determining structural parameters (such as core and tidal radii, ellipticities, and orientations) for M31's globular clusters.

Pre‐Diagnostic Features of Multiple Sclerosis in a Diverse UK Cohort: A Nested Case–Control Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Many patients with Multiple Sclerosis (MS) experience nonspecific symptoms prior to diagnosis. This period—the 'MS prodrome'—has been described in socio‐economically homogeneous cohorts to date. It remains unclear to what extent events prior to an MS diagnosis differ according to social determinants of health. Methods We conducted a
