Early type galaxies

The mass fluctuation spectrum gives rise to collapsed objects from galaxies to groups to rich clusters. The systems dominated by old stars - early type galaxies, elliptical-dominated groups, and rich clusters - all have gaseous halos... [Pg.23]

The phenomenon of cooling flows , described for luminous clusters, also applies to other systems with gaseous atmospheres. In particular, galaxy groups, the poorer cousins of rich clusters, (e.g., Helsdon et al. 2001) and individual early type galaxies with their luminous, X-ray coronae (Forman, Jones Tucker 1985) also frequently have short gas cooling times at their centers (Thomas et al. 1986). [Pg.37]

Comparing Figures 3 and 4, early-type galaxies and the bulges of spiral galaxies are dominated by starlight emission. The disks of late-type galaxies, on the other hand, are dominated by warm dust emission. [Pg.52]

Figure 7. Warm dust emission in early-type galaxies. Six galaxies are shown, each with separate images in stellar emission (3.6 /um) and warm dust emission (8.0 pm non-stellar ). The top three galaxies are classified as ellipticals and show no sign of warm dust emission at 8.0 pm. The bottom three galaxies are classified as lenticulars and show resolved warm dust. NGC 4203 appears face-on with several spiral arms emanating out from its nucleus, NGC 5363 appears somewhat inclined and shows two arms, and NGC 1023 shows a smooth distribution of dust. Figure 7.

Three of six early-type galaxies observed exhibit dust emission that is organized into spiral arm or inner disk-like structures,... [Pg.58]

Most SMBHs have been identified in early type galaxies [16] (exceptions include the mentioned maser galaxies, the Galaxy and the two nearby Sbs M31... [Pg.166]

As expected the K<18 sample seems to be mostly comprised of early type galaxies. This is shown by both their fairly red R-K colors and their deep D(4000) (Figure 2). Additionally, most of the galaxies do not have strong emission lines, OII[3727] has an equivalent width of less than lOA in about 90% of the galaxies in contrast to the blue selected samples (Broadhurst et... [Pg.34]
