We present an analysis of Hubble Space Telescope/WFPC2 images of nine nearby galaxies in Sculptor. We derive their distances from the luminosity of the tip of the red giant branch stars with a typical accuracy of ∼12%. Their distances are 4.21 Mpc (Sc 22), 4.92 Mpc (DDO 226), 3.94 Mpc (NGC 253), 3.40 Mpc (KDG 2), 3.34 Mpc (DDO 6), 3.42 Mpc (ESO 540-030), 4.43 Mpc (ESO 245-05), 4.27 Mpc (UGCA 442), and 3.91 Mpc (NGC 7793). The galaxies are concentrated in several spatially separated loose groups…

Distances to nearby galaxies around IC 342
We present an analysis of Hubble Space Telescope/WFPC2 images of six nearby galaxies in the projected vicinity of IC 342: Cas dSph, KK 35, UGCA 86, Cam A, NGC 1560, and Cam B. We derive distances to
The Recent Evolution of the Dwarf Starburst Galaxy NGC 625 from Hubble Space Telescope Imaging
New Hubble Space Telescope WFPC2 imaging of the dwarf starburst galaxy NGC 625 is presented. These data, which are 80% complete to V and I magnitudes of 26.0 and 25.3, respectively, allow us to study
Distance to NGC 253 based on the planetary nebula luminosity function
We identify a sample of 14 planetary nebulae in the nearby starburst disc galaxy NGC 253, using broad- and narrow-band imaging. A simple model of the stellar and dust layers in the galaxy shows that
We conducted a Chandra ACIS observation of the nearby Sculptor Group Sd galaxy NGC?7793 as part of a multiwavelength study of supernova remnants (SNRs) in nearby galaxies. At the assumed distance to
The Araucaria Project: The Distance to the Sculptor Group Galaxy NGC 55 from a Newly Discovered Abundant Cepheid Population
We have detected, for the first time, Cepheid variables in the Sculptor Group SB(s)m galaxy NGC 55. From wide-field images obtained in the optical V and I bands during 77 nights in 2002-2003, we have
Gas and dark matter in the Sculptor group: NGC 300
We used the Australia Telescope Compact Array to map a large field of approximately 2° x 2° around the Sculptor group galaxy NGC 300 in the 21-cm line emission of neutral hydrogen. We achieved a 5σ H
The acs nearby galaxy survey treasury. XI. the remarkably undisturbed NGC 2403 disk
We present detailed analysis of color-magnitude diagrams of NGC 2403, obtained from a deep (m 28) Hubble Space Telescope (HST) Wide Field Planetary Camera 2 observation of the outer disk of NGC 2403,
Distance determination to NGC 55 from the planetary nebula luminosity function
We analysed (O III), H , and continuum images of the Sculptor group spiral galaxy NGC 55 obtained with the WFI instrument at the 2.2-m telescope of ESO. We identified 21 new planetary nebula
Optical spectra of supernova remnant candidates in the Sculptor Group galaxy NGC 300
We present moderate-resolution (<5 Å) long-slit optical spectra of 51 nebular objects in the nearby Sculptor Group galaxy NGC 300 obtained with the 2.3 meter Advanced Technology Telescope at Siding
A survey for OB associations in the Sculptor Group spiral galaxy NGC 7793
We report on the results from application of an objective algorithm (PLC) to find OB associations, to B and V images of the Sculptor spiral galaxy NGC 7793, which were obtained with the ESO VLT and


Galaxy flow in the Canes Venatici I cloud
We present an analysis of Hubble Space Telescope/WFPC2 images of eighteen galaxies in the Canes Venatici I cloud. We derive their distances from the luminosity of the tip of the red giant branch
Surface Brightness Fluctuation Distances to Dwarf Elliptical Galaxies in the Sculptor Group
As part of an ongoing search for dwarf elliptical galaxies (dE's) in the vicinity of the Local Group (Jerjen et al.), we acquired deep B- and R-band images for five dE candidates identified on
Detection of the red giant branch stars in m82 using the hubble space telescope
We present color-magnitude diagrams and luminosity functions of stars in two halo regions of the irregular galaxy in M82, based on F555W and F814W photometry taken with the Hubble Space Telescope
Tip of the red giant branch distance for the Sculptor group dwarf ESO 540-032 ?
We present the rst VICCD photometry for the Sculptor group galaxy ESO 540-032 obtained at the Very Large Telescope UT1+FORS1. The (I; V I) colour-magnitude diagram indicates that this intermediate-
Hubble Space Telescope Photometry of the Dwarf Spheroidal Galaxy ESO 410-G005*
We present Hubble Space Telescope WFPC2 imaging of the nearby low surface brightness dwarf spheroidal galaxy ESO 410-G005, which has been resolved into stars for the first time. The resulting

We present results of two 21-cm Hi surveys performed with the Australia Telescope Compact Array in the nearby Centaurus A and Sculptor galaxy groups. These surveys are sensitive to compact Hi clouds
New H I-detected Galaxies in the Zone of Avoidance
We present the first results of a blind H I survey for galaxies in the southern zone of avoidance with a multibeam receiver on the Parkes telescope. This survey is expected to eventually catalog
The very local Hubble flow
We present Hubble Space Telescope/WFPC2 images of eighteen galaxies situated in the vicinity of the Local Group (LG) as part of an ongoing snapshot survey of nearby galaxies. Their distances derived
HI observations of nearby galaxies - I. The first list of the Karachentsev catalog
We present H i observations of the galaxies in the second list of the Karachentsev catalog of pre- viously unknown nearby dwarf galaxies (Karachentseva et al. 1999). This survey covers an area of
