DDO 43 : A Prototypical Dwarf Irregular Galaxy ?

We present sensitive and high resolution 21 cm observations of the dwarf irregular (dIm) galaxy DDO 43, in conjunction with optical broad and narrow band images in U, B, V, and Hα. The observations are used to examine the relationship between its H i morphology and kinematics to past and present star formation. Optically, it is a small (R25 = 990 pc), faint (MB of −14.0) Im with a slightly boxy...

The Star Formation History of the Pegasus Dwarf Irregular Galaxy

The star formation history (SFH) of the Pegasus dIr, a likely Local Group member at 0.95 Mpc from the Milky Way, is investigated. We characterize the SFH by two basic functions: the star formation rate, ψ(t), and the chemical enrichment law, Z(t). It has been derived by comparing the color-magnitude diagram of the resolved stars in Pegasus, with a total of 189 model diagrams produced with diffe...

Stellar Populations of the Sagittarius Dwarf Irregular Galaxy

We present deep BV RI CCD photometry of the stars in the dwarf irregular galaxy SagDIG. The color-magnitude diagrams of the measured stars in SagDIG show a blue plume which consists mostly of young stellar populations, and a well-defined red giant branch (RGB). The foreground reddening of SagDIG is estimated to be E(B − V ) = 0.06. The tip of the RGB is found to be at ITRGB = 21.55 ± 0.10 mag. ...

Kinematics of the dwarf irregular galaxy GR 8

We present deep, high velocity resolution (∼ 1.6 km s) Giant Meterwave Radio Telescope HI 21cm synthesis images for the faint (MB ∼ −12.1) dwarf irregular galaxy GR8. We find that the velocity field of the galaxy shows a clear systematic large scale pattern, with a maximum amplitude ∼ 10 km s. Neither pure rotation, nor pure radial motion alone can fit the observed velocity field; however a com...
