Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies

European Physical Journal C: Particles and Fields
In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $$\Lambda \textrm{CDM}$$ Λ CDM cosmological model and the observed dark ...

A link between feedback outflows and satellite galaxy suppression

, 2013
We suggest a direct link between the two "missing" baryon problems of contemporary galaxy formation theory: (1) that large galaxies are known to contain too little gas and stars and (2) that too few dwarf satellite galaxies are observed around large ...

Roche Lobe Overflow from Dwarf Stellar Systems

, 2003
We use both analytical analyses and numerical simulations to examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters.

Non-parametric star formation histories for 5 dwarf spheroidal galaxies of the local group [PDF]

, 2000
We use recent HST colour-magnitude diagrams of the resolved stellar populations of a sample of local dSph galaxies (Carina, LeoI, LeoII, Ursa Minor and Draco) to infer the star formation histories of these systems, $SFR(t)$.

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 ...

Star Formation and Feedback in Dwarf Galaxies

, 2003
We examine the star formation history and stellar feedback effects of dwarf galaxies under the influence of extragalactic ultraviolet radiation. We consider the dynamical evolution of gas in dwarf galaxies using a one-dimensional, spherically symmetric ...

Reconciling dwarf galaxies with LCDM cosmology: Simulating a realistic population of satellites around a Milky Way-mass galaxy [PDF]

, 2016
Low-mass "dwarf" galaxies represent the most significant challenges to the cold dark matter (CDM) model of cosmological structure formation. Because these faint galaxies are (best) observed within the Local Group (LG) of the Milky Way (MW) and Andromeda (

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.

Deciphering the role of epistemic injustice in school‐based citizen science: Sources, implications, and possible ways for mitigation

Journal of Research in Science Teaching, Volume 62, Issue 5, Page 1350-1387, May 2025.
Abstract Participation in citizen science, a research approach in which nonscientists take part in performing research, is a growing practice in schools. A main premise in school‐based citizen science is that through their participation, students and teachers make meaningful contributions to the advancement of science.
