“…Together with earlier published TRGB distances to four other galaxies (Karachentsev et al , 2002 and the distance to NGC 300 from Cepheids (Freedman et al 1992), this gives us a basis for a more detailed study of the structure of the Sculptor complex.…”

Abstract. 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 from the magnitude of the tip of the red giant branch are 1.92 ± 0.10 Mpc (ESO 294-010), 3.06 ± 0.37 (NGC 404), 3.15 ± 0.32 (UGCA 105), 1.36 ± 0.07 (Sex B), 1.33 ± 0.08 (NGC 3109), 2.64 ± 0.21 (UGC 6817), 2.86 ± 0.14 (KDG 90), 2.27 ± 0.19 (IC 3104), 2.54 ± 0.17 (UGC 7577), 2.56 ± 0.15 (UGC 8508), 3.01 ± 0.29 (UGC 8651), 2.61±0.16 (KKH 86), 2.79±0.26 (UGC 9240), 1.11±0.07 (SagDIG), 0.94±0.04 (DDO 210), 2.07±0.18 (IC 5152), 2.23 ± 0.15 (UGCA 438), and 2.45 ± 0.13 (KKH 98). Based on the velocity-distance data for 36 nearest galaxies around the LG, we find the radius of the zero-velocity surface of the LG to be R0 = (0.94±0.10) Mpc, which yields a total mass MLG = (1.3 ± 0.3) × 10 12 M . The galaxy distribution around the LG reveals a Local Minivoid which does not contain any galaxy brighter than MV = −11 mag within a volume of ∼100 Mpc 3 . The local Hubble flow seems to be very cold, having a one-dimensional mean random motion of ∼30 km s −1 . The best-fit value of the local Hubble parameter is 73 ± 15 km s −1 Mpc −1 . The luminosity function for the nearby field galaxies is far less steep than one for members of the nearest groups.

“…Unfortunately the distance to NGC 300 is rather uncertain at the present time; distance moduli obtained by different authors differ quite significantly. Based on an analysis of a variety of distance indicators, van den Bergh (1992) found a distance modulus of 26.0 mag, while Freedman et al (1992) obtained a value of 26.66 mag, using BV RI CCD observations of Cepheids in this galaxy. If we adopt the latter value, our brightness cutoff corresponds to an absolute magnitude of M v = −4.7 mag.…”

Abstract. We present results of a search for OB associations in NGC 300. Using an automatic and objective method (PLC technique) 117 objects were found. Statistical tests indicate that our sample is contaminated by less than 10 detections due to random concentrations of blue stars. Spatial distributions of detected associations and H II regions are strongly correlated. The size distribution reveals a significant peak at about 60 µrad which corresponds to 125 parsecs if a distance modulus of 26.66 mag is assumed. Besides the objects with sizes corresponding to typical associations we also found several much larger objects. A second level application of our detection method revealed that most of these are composed of smaller subgroups, with sizes of about 100 pc.
