J/AJ/139/1857       Sample of major galaxy pairs at z=0.08-0.38  (Woods+, 2010)

Triggered star formation in galaxy pairs at z = 0.08-0.38. Woods D.F., Geller M.J., Kurtz M.J., Westra E., Fabricant D.G., Dell'Antonio I. <Astron. J., 139, 1857-1870 (2010)> =2010AJ....139.1857W
ADC_Keywords: Galaxy catalogs ; Photometry ; Spectroscopy Keywords: galaxies: active - galaxies: interactions - galaxies: stellar content Abstract: We measure the strength, frequency, and timescale of tidally triggered star formation at redshift z=0.08-0.38 in a spectroscopically complete sample of galaxy pairs drawn from the magnitude-limited redshift survey of 9825 Smithsonian Hectospec Lensing Survey galaxies with R<20.3. To examine the evidence for tidal triggering, we identify a volume-limited sample of major (|ΔMR|<1.75, corresponding to mass ratio >1/5) pair galaxies with MR←20.8 in the redshift range z=0.08-0.31. Description: The SHELS magnitude-limited redshift survey includes 9825 galaxies with total R-band magnitude R<20.3. The galaxies are selected from the Deep Lens Survey F2 field R-band images. We obtained spectroscopy using Hectospec at the MMT. File Summary:

Note (1): Typical error for cz in emission line galaxies is 34km/s and 65km/s for absorption line galaxies (Section 2.3). Note (2): Typical error is 0.05mag (Section 2.2). Note (3): k+e corrected. Typical error is ∼0.1mag, varies with redshift and galaxy type (Section 2.2). Note (4): Typical error is 4.5% (Section 2.3). Note (5): Typical error is 30% (Section 2.3.1).
