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.

AGN feedback in dwarf galaxies [PDF]

, 2017
Dwarf galaxy anomalies, such as their abundance and cusp-core problems, remain a prime challenge in our understanding of galaxy formation. The inclusion of baryonic physics could potentially solve these issues, but the efficiency of stellar feedback is ...

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

Efficiency of Metal Mixing in Dwarf Galaxies [PDF]

Understanding the Enrichment of Heavy Elements by the Chemodynamical Evolution Models of Dwarf Galaxies, 2017
Metal mixing plays a critical role in the enrichment of metals in galaxies. The abundance of elements such as Mg, Fe, and Ba in metal-poor stars helps us understand the metal mixing in galaxies.

HyperFLINT: Hypernetwork‐based Flow Estimation and Temporal Interpolation for Scientific Ensemble Visualization

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We present HyperFLINT (Hypernetwork‐based FLow estimation and temporal INTerpolation), a novel deep learning‐based approach for estimating flow fields, temporally interpolating scalar fields, and facilitating parameter space exploration in spatio‐temporal scientific ensemble data. This work addresses the critical need to explicitly incorporate

Active Galactic Nucleus Quenching in Simulated Dwarf Galaxies

The Astrophysical Journal, 2023
We examine the quenching characteristics of 328 isolated dwarf galaxies $\left({10}^{8}\lt {M}_{\mathrm{star}}/{M}_{\odot }\lt {10}^{10}\right)$ within the Romulus25 cosmological hydrodynamic simulation.

Properties of the Dwarf Galaxy Population in Galaxy Clusters

, 2008
We present the observational properties of the dwarf galaxy population (Mr > M*+1) corresponding to one of the largest samples of spectroscopically confirmed galaxy cluster members reported in the literature. We have observed that red dwarf galaxies (u-r

The rotation curves shapes of late-type dwarf galaxies [PDF]

, 2008
We present rotation curves derived for a sample of 62 late-type dwarf galaxies that have been observed as part of the Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) project.

Missing dark matter in dwarf galaxies [PDF]

, 2016
We use cosmological hydrodynamical simulations of the APOSTLE project to examine the fraction of baryons in CDM haloes that collect into galaxies. This ‘galaxy formation efficiency’ correlates strongly and with little scatter with halo mass, dropping ...

Botanical Extract–Infused Shampoo and Hair Tonic for Hair Loss in Androgenetic Alopecia: A TREND‐Compliant, Prospective Single‐Arm Preexperimental Study

Journal of Cosmetic Dermatology, Volume 24, Issue 6, June 2025.
ABSTRACT Background Androgenetic alopecia (AGA) is the most prevalent form of hair loss, often leading to treatment discontinuation due to the adverse effects and perceived ineffectiveness of conventional treatments. Botanical extracts are gaining attention for their potential benefits in managing AGA with minimal side effects.
