Hunting Faint Dwarf Galaxies in the Field Using Integrated Light Surveys [PDF]

, 2017
We discuss the approach of searching the lowest mass dwarf galaxies, , in the general field, using integrated light surveys. By exploring the limiting surface brightness-spatial resolution (μeff,lim−θ) parameter space, we suggest that faint field dwarfs ...

Galaxy Threshing and the Formation of Ultracompact Dwarf Galaxies [PDF]

The Astrophysical Journal, 2001
Recent spectroscopic and morphological observational studies of galaxies around NGC 1399 in the Fornax Cluster (Drinkwater et al. 2000b) have discovered several `ultra-compact dwarf' galaxies with intrinsic sizes of $\sim$ 100 pc and absolute $B$ band magnitudes ranging from -13 to -11 mag.

BAF60/SWP73 subunits define subclasses of SWI/SNF chromatin remodelling complexes in Arabidopsis

New Phytologist, Volume 247, Issue 2, Page 791-812, July 2025.
Summary Evolutionarily conserved switch‐defective/sucrose nonfermentable (SWI/SNF) ATP‐dependent chromatin remodelling complexes (CRCs) alter nucleosome positioning and chromatin states, affecting gene expression to regulate important processes such as proper development and hormonal signalling pathways.

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 ...

X-Ray and Ultraviolet Properties of AGNs in Nearby Dwarf Galaxies [PDF]

, 2016
We present new Chandra X-ray Observatory and Hubble Space Telescope observations of eight optically selected broad-line active galactic nucleus (AGN) candidates in nearby dwarf galaxies (z < 0.055).

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

X-RAY DETECTED ACTIVE GALACTIC NUCLEI IN DWARF GALAXIES AT 0 < z < 1 [PDF]

, 2016
We present a sample of accreting supermassive black holes (SMBHs) in dwarf galaxies at . We identify dwarf galaxies in the NEWFIRM Medium Band Survey with stellar masses of that have spectroscopic redshifts from the DEEP2 survey and lie within the region

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.

LITTLE THINGS in 3D: robust determination of the circular velocity of dwarf irregular galaxies [PDF]

, 2016
Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H I discs. The study of the kinematics of such discs is a powerful tool to estimate the total matter distribution at these very small scales.
