Clarification of the Nature of the Galaxy CFC97 Cen 05

open access: yes, 2004
The galaxy CFC97 Cen 05 has in the past been considered an HI-rich dwarf galaxy in the nearby Centaurus A group. We have used Australia Telescope Compact Array observations to show that the HI associated with CFC97 Cen 05 by Cote et al.

Quantum WDM fermions and gravitation determine the observed galaxy structures

open access: yes, 2013
Quantum mechanics is necessary to compute galaxy structures at kpc scales and below. This is so because near the galaxy center, at scales below 10 - 100 pc, warm dark matter (WDM) quantum effects are important: observations show that the interparticle ...

A spectroscopic study of the merging dwarf galaxy PGC 007782

open access: yesBibechana
We did a detailed spectroscopic study of PGC 007782, an interacting emission type dwarf galaxy. This study utilized the optical spectrum of emission lines to explore the system of interacting dwarf galaxies.

The chemical evolution of the Galactic Bulge seen through micro-lensing events

open access: yesEPJ Web of Conferences, 2012
Galactic bulges are central to understanding galaxy formation and evolution. Here we report on recent studies using micro-lensing events to obtain spectra of high resolution and moderately high signal-to-noise ratios of dwarf stars in the Galactic bulge.

Has the Palomar 14 Globular Cluster Been Captured by the Milky Way?

open access: yesThe Astrophysical Journal
We examine a new scenario to model the outer halo globular cluster (GC) Palomar 14 (Pal 14) over its lifetime by performing a comprehensive set of direct N -body calculations.

An Analytical Galactic Chemical Evolution Model with Gas Inflow and a Terminal Wind

open access: yesThe Astrophysical Journal
We present a new analytical galactic chemical evolution (GCE) model with gas inflow, internally caused outflow, and extra gas loss after a period of time. The latter mimics the ram pressure stripping of a dwarf satellite galaxy near the pericenter of its
