The location of the 10 LGS fields in M31.
The galaxies of the Local Group serve as our laboratories for understanding star formation and stellar evolution in differing environments: the galaxies currently active in star-formation in the Local Group cover a factor of 10 in metallicity and span a range of Hubble types from dwarf spheroidal to Irr to Sb and Sc. The Survey of Local Group Galaxies Currently Forming Stars (LGS) obtains UBVRI, Hα, [SII], and [OIII] KPNO and CTIO 4-m mosaic images of nearby galaxies selected on the basis of current star formation. In the Local Group, this sample includes M31, M33, NGC 6822, IC 10, WLM, Pegasus, and Phoenix. Sextans A and Sextans B, located just beyond the Local Group are also included.
LGS at a Glance
|Years of Observation||2000-2002|
|Sample:||M31, M33, NGC 6822, IC 10, WLM, Pegasus, Phoenix, Sextans A, and Sextans B imaged with the KPNO and CTIO 4-m mosaic CCD cameras.|
|Bands||U, B, V, R, I, Hα, [SII], and [OIII]|
|Number of images||NGC 6822, IC 10, WLM, Pegasus, Phoenix, Sextans A, and Sextans B (Single field galaxies, 5 exposures/filter + 1 stacked image/filter => 7 galaxies x 8 filters x 6 images = 336 images) + M33 (3 fields => 144 images) + M31 (10 fields => 480 images).|
