我们测量了 MASSIVE 巡天中 90 个早期型星系 (ETG) 半径的函数，这是一项体积有限的积分场光谱 (IFS) 星系巡天，目标是所有北方天空 ETG，其绝对 K 波段星等为 MK 5 Mpc 尺度) 和恒星数量，正如卫星在较稠密的环境中较早淬火时所预期的那样。
We measure the stellar populations as a function of the radius for 90 early-type galaxies (ETGs) in the MASSIVE survey, a volume-limited integral-field spectroscopic (IFS) galaxy survey targeting all northern-sky ETGs with an absolute K-band magnitude of MK 5 Mpc scales) and the stellar populations, as expected if satellites are quenched earlier in denser environments.
