The nature of ISOCAM galaxies in the Hubble Deep Field South
SPRINGER PROC PHYS 88 (2001) 255-260
Abstract:
The various deep ISOCAM surveys revealed a new class of infrared luminous galaxies which are characterized by a high rate of evolution and are found at redshifts of zsimilar to1. Here we report results of our near-infrared VLT-ISAAC spectroscopic survey aimed at characterising the nature of these sources. We find that the rest-frame R-band spectra resemble those of powerful dust enshrouded starbursts. More recent detailed studies revealed that some of these systems are in fact extremely massive galaxies.The orthogonal bulge-disc decoupling in NGC 4698
ASTROPHYS SPACE SCI 276:2-4 (2001) 467-473
Abstract:
The R-band isophotal map of the Sa galaxy NGC 4698 shows that the inner region of the bulge is elongated perpendicularly to the major axis of the disc. At the same time a central stellar velocity gradient is found along the minor axis of the disc. The same properties have also been recognized in the Sa galaxy NGC 4672. This remarkable geometric and kinematic decoupling is a direct indication that a second event occurred in the history of these galaxies suggesting that acquisition phenomena could play a primary role in the formation of early-type spirals.The peculiar motions of early-type galaxies in two distant regions - VI.
