In Hubble’s classification scheme, dwarf irregular galaxies (dIs) are low luminosity systems (MB≳ -16) which are at the end of the galaxy morphological sequence and which lack both a dominating nucleus and rotational symmetry [1]. We concentrate here on a class of dIs which are so extreme in these properties that they appear almost stellar in appearance, with no obvious underlying galaxy, at least on the Palomar Sky Survey prints (PSS), the blue compact dwarf galaxies (BCDs). Our motivation is twofold: (1) it is easier to discuss the physical characteristics of dIs by focussing on their extreme manifestations; and (2) the properties of dIs have been well reviewed elsewhere [2]. The present review of BCDs is intended to be complementary and will attempt to contrast the properties of BCDs with those of dIs.

popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
