Deep MOS Spectroscopy of NGC 1316 Globular Clusters

Galaxies, 2017
The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

A new measurement of the evolving near-infrared galaxy luminosity function out to z~4: a continuing challenge to theoretical models of galaxy formation

, 2008
We present the most accurate measurement to date of cosmological evolution of the near-infrared galaxy luminosity function, from the local Universe out to z~4.

The Effect of Immersion Technology on the Quality of Life in Older Adults: A Systematic Review

AGING MEDICINE, EarlyView.
Immersive technologies, especially virtual reality (VR), significantly improve the quality of life for older adults by enhancing physical health, cognitive function, and psychological well‐being. These technologies can be adapted to meet individual needs, making them an effective tool for addressing the challenges of aging.

Star Formation and Magnetic Field Amplification due to Galactic Spirals

The Astrophysical Journal
We use global MHD galaxy simulations to investigate the effects of spiral arms on the evolution of magnetic fields and star formation within a self-regulated interstellar medium.

RELICS: Small-scale Star Formation in Lensed Galaxies at z = 6–10

The Astrophysical Journal, 2023
Detailed observations of star-forming galaxies at high redshift are critical to understanding the formation and evolution of the earliest galaxies. Gravitational lensing provides an important boost, allowing observations at physical scales unreachable in

Young star clusters: Clues to galaxy formation and evolution [PDF]

, 2003
Young clusters are observed to form in a variety of interacting galaxies and violent starbursts, a substantial number resembling the progenitors of the well-studied globular clusters in mass and size.

AIEgen‐Based and Smartphone‐Assisted On‐Site Quantitation of Cystatin C for Monitoring of Chronic Kidney Disease

Aggregate, EarlyView.
By employing new protein‐templated AIEgen Ir@BSA as the phosphorescence signal indicator and papain as the biomolecular recognition element, a straightforward protocol for Cys C quantitation has been developed. On‐site quantitation of Cys C in clinical serum samples has been successfully demonstrated using a smartphone‐based portable phosphorescence ...

Overmerging and M/L ratios in phenomenological galaxy formation models

, 1999
We show that the discrepancy between the Tully-Fisher relation and the luminosity function predicted by most phenomenological galaxy formation models is mainly due to overmerging of galaxy haloes.

Tau Amyloid Corona‐Shelled Nanoparticle‐Based Drug Screening Platform for Discovering Tau Oligomer‐Degrading Drugs

Aggregate, EarlyView.
Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.
