Abundance ratios in dwarf elliptical galaxies
Ş. Şen, R. F. Peletier, A. Boselli +14
We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magn…
UGC 4703 interacting pair near to an isolated spiral galaxy NGC 2718: A Milky Way Magellanic Cloud analogue
Sanjaya Paudel, C. Sengupta
We present an analysis of physical and morphological properties of an interacting pair of dwarf galaxies UGC 4703 located at the vicinity of an isolated Milky-Way (MW) type spiral…
Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
Linda Urich, Thorsten Lisker, Joachim Janz +11
Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar population properties. To…
HI, star formation and tidal dwarf candidate in the Arp 305 system
C. Sengupta, T. C. Scott, S. Paudel +3
We present results from our Giant Metrewave Radio Telescope (GMRT) HI observations of the Arp 305 system. The system consists of two interacting spiral galaxies NGC 4016 and NGC 40…
