In this review, we presented results from parallel and other deep HST
surveys. In Section 2,
we summarized HST's morphological evidence for the evolution of
different galaxy types
for 19 B
27.5 mag: early types
(E/S0's and Sabc's) evolved the least since z
1, and late types (Sd/Irr's+Mergers) most rapidly. With better restframe
ANN's, these
results can be extended in the HDF and in future deep NICMOS and ACS images for
B
29 or H
25 mag. This will cover
the bulk of galaxies in the range z ~ 1-3. In
Section 2 we summarized the WFPC2 F410M
medium band searches for faint compact
Ly
emitting objects at z
2.4. The unexpected success of finding these objects provides
an important confirmation of CDM theories, leads us to the question
whether or not all
high z star-forming systems are obscured by dust, and provides
clues as to where the
long sought Ly
emitting
primeval galaxies may be hiding - in many small pieces. The
existence of any larger scale structure at z
2-3 clearly begs further
investigation. In
Section 3, the radio galaxy 53W002 provided
important clues as to how a luminous early-type
galaxy seen today may have formed. For this object at least, this may
have started with
jet-induced star-formation (with an aligned cone associated with its
AGN), soon followed
by the formation of an r1/4-like bulge and within a
few Gyr by a massive disk, which may
get destroyed later by subsequent mergers with the surrounding
sub-galactic objects.
