Identification of Star Clusters in M31 from PAndAS Images Based on Deep Learning

The Astrophysical Journal Supplement Series
The identification of star clusters holds significant importance in studying galaxy formation and evolution history. However, the task of swiftly and accurately identifying star clusters from vast amounts of photometric images presents an immense ...

Centrally concentrated star formation in young clusters

Astronomy & Astrophysics
The study of star cluster evolution necessitates modeling how their density profiles develop from their natal gas distribution. Observational evidence indicates that many star clusters follow a Plummer-like density profile.

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

The Star Cluster Population of M51: II. Age distribution and relations among the derived parameters

, 2005
We use archival Hubble Space Telescope observations of broad-band images from the ultraviolet (F255W-filter) through the near infrared (NICMOS F160W-filter) to study the star cluster population of the interacting spiral galaxy M 51.

Between the Cosmic-Ray “Knee” and the “Ankle”: Contribution from Star Clusters

The Astrophysical Journal
We show that massive, young star clusters may be possible candidates that can accelerate Galactic cosmic rays (CRs) in the range of 10 ^7 –10 ^9 GeV (between the “knee” and “ankle”).

Micro-tidal disruption events in young star clusters

Astronomy & Astrophysics
Context. Dense young star clusters (YSCs) are ideal environments for dynamical interactions between stars and stellar compact objects, such as black holes and neutron stars.

Risk of Non‐Arteritic Anterior Ischemic Optic Neuropathy in Idiopathic Intracranial Hypertension Patients Treated with GLP‐1 Receptor Agonists

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) have demonstrated significant weight‐reducing effects and may offer benefits in idiopathic intracranial hypertension (IIH); however, recent concerns about the risk of non‐arteritic anterior ischemic optic neuropathy (NAION) have emerged.

Constraining star formation timescales with molecular gas and young star clusters

, 2021
Star formation provides insight into the physical processes that govern the transformation of gas into stars. A key missing piece in a predictive theory of star formation is the link between scales of individual stars and star clusters up to entire ...

Using Rapid Rotators as Tracers of Multiplicity Statistics as a Function of Stellar Density

The Astrophysical Journal
Recent works have identified that rapidly rotating stars are predominantly binaries with separations of a few to a few tenths of an astronomical unit. This is a crucial range of separation that is often inaccessible to searches of binary stars, providing

Massive star clusters in the semi-analytical galaxy formation model L-Galaxies 2020

Astronomy & Astrophysics
It has been established that a direct link exists between the formation history of star cluster populations and their host galaxies. However, our lack of understanding of the assembly of star cluster populations impedes our ability to use them as tracers
