... I will touch upon the following points: ­ fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; ­ prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; ­ apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; ­ old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...

It contains the first Catalogue of variable stars in external galaxies as well as a Catalogue of extragalactic supernovae. ... Note that NGC 1466 is a globular cluster (not a galaxy) between the LMC and the SMC; we presented it separately, because it is not clear to which galaxy to attribute its variable stars. Note on VarNo: variable star No within the galaxy. ...

... Sky surveys and deep fields of ground-based and space telescopes History · William Herschel (1738-1822) was the first to formulate the problem of global sky surveys to study the structure and evolution of the world outside the solar system. ... The VVDS (VIMOS-VLT Deep Survey) is a photometric and spectroscopic survey of 100,000 galaxies within several deep fields covering 16 sq. deg. with the VIsible Multi-Object Spectrograph (VIMOS) on the ESO VLT telescope. ...
