B , V , I – photometry of 20 dwarf irregular galaxies within 10
نویسندگان
چکیده
CCD – photometry is presented for 20 dIrr galaxies situated in the nearby complexes CenA/M83, and CVnI as well as in the general field of the Local Volume. We present integrated magnitudes of the galaxies in B, V, Ibands and also surface brightness profiles to a median isophote μB ∼ 28 mag sq. arcsec . The popular Sersic parameterization of surface brightness profiles generally does a poor job of simultaneously fitting the inner cores and outer exponential surface brightness fall-offs observed in many of our targets. The observed sample is a part of a general project to image about 500 nearby (D < 10 Mpc) dwarf galaxies in multiple bands.

We present deep BVRI band images and H i line observations of the nearby, low surface brightness galaxy ESO215–G?009 which were obtained with the ANU 2.3-m Telescope and the Australia Telescope Compact Array, respectively. ESO215–G?009 was selected from the HIPASS Bright Galaxy Catalog because it has the second highest H i mass-to-light ratio of the galaxies with measured B band apparent magnit...
متن کاملPulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I
We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

R-band surface photometry is presented for 171 late-type dwarf and irregular galaxies. For a subsample of 46 galaxies B-band photometry is presented as well. We present surface brightness profiles as well as isophotal and photometric parameters including magnitudes, diameters and central surface brightnesses. Absolute photometry is accurate to 0.1 mag or better for 77% of the sample. For over 8...
متن کاملStellar Populations of Dwarf Elliptical Galaxies: Ubvri Photometry of Dwarf Elliptical Galaxies in the Virgo Cluster
We present UBVRI surface photometry for 16 dwarf elliptical galaxies in the Virgo Cluster with previously measured kinematic properties. The global optical colors are red, with median values for the sample of 0.24 ± 0.03 in (U–B), 0.77 ± 0.02 in (B– V), and 1.02 ± 0.03 in (V–I). We recover the well known color-magnitude relation for cluster galaxies, but find no significant difference in domina...
متن کاملStellar 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. ...
