J/MNRAS/405/1089   Photometric scaling for L/S0 galaxies   (Laurikainen+ 2010)

Photometric scaling relations of lenticular and spiral galaxies. Laurikainen E., Salo H., Buta R., Knapen J.H., Comeron S. <Mon. Not. R. Astron. Soc., 405, 1089-1118 (2010)> =2010MNRAS.405.1089L
ADC_Keywords: Galaxies, photometry ; Morphology Keywords: galaxies: elliptical and lenticular, cD - galaxies: evolution - galaxies: structure Abstract: Photometric scaling relations are studied for S0 galaxies and compared with those obtained for spirals. New two-dimensional multi-component decompositions are presented for 122 early-type disc galaxies, using deep Ks-band images. Combining them with our previous decompositions, the final sample consists of 175 galaxies (Near-Infrared Survey of S0s, NIRS0S: 117 S0s + 22 S0/a and 36 Sa galaxies). As a comparison sample we use the Ohio State University Bright Spiral Galaxy Survey (OSUBSGS) of nearly 200 spirals, for which similar multi-component decompositions have previously been made by us.
