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 ...

The Outer Edges of Dwarf Irregular Galaxies: Stars and Gas
, 2002 We have in recent years come to view dwarf galaxy evolution in the broader context of the cosmic evolution of large-scale structure. Dwarf galaxies, as the putative building blocks of hierarchical galaxy formation, and also as the most numerous galaxies ...

Identifying Old Tidal Dwarf Irregulars [PDF]
, 2000 We examine the observational consequences of the two possible origins for irregular galaxies: formation from collapse of a primordial cloud of gas early in the age of the Universe, and formation from tidal tails in an interaction that could have occured ...

Evidence for Mass-dependent Evolution of Transitional Dwarf Galaxies in the Virgo Cluster
The Astrophysical JournalThe presence of transitional dwarf galaxies in cluster environments supports the hypothesis that infalling star-forming galaxies are transformed into quiescent early-type dwarf galaxies (ETdGs) through environmental effects.

FIGGS: Faint Irregular Galaxies GMRT Survey
, 2007 The Faint Irregular Galaxies GMRT Survey (FIGGS) is a large program aimed at providing a comprehensive and statistically robust characterisation of the neutral ISM properties of faint (M_B > -14.5), nearby, gas rich, dwarf irregular galaxies using the ...

The fundamental plane of dwarf irregular galaxies [PDF]
Astronomy & Astrophysics, 2008 Aims. Near-IR photometry of dwarf irregular galaxies (dIs) has been acquired to expand the sample of objects suitable for investigating the fundamental plane (FP) discovered previously by us. Data for blue compact dwarfs (BCDs), dwarf ellipticals (dEs), and dwarf spheroidal galaxies (dSphs) are amalgamated to evaluate how closely these classes of ...

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 Plants can be exposed to ionising radiation not only in Space but also on Earth, due to specific technological applications or after nuclear disasters. The response of plants to ionising radiation depends on radiation quality/quantity and/or plant characteristics. In this paper, we analyse some growth traits, leaf anatomy, and ecophysiological features
