Our mechanism is general and would have operated in all star-forming galaxies at redshifts z>~ 10. Once removed, the cusp cannot be reintroduced during the subsequent mergers involved in the build-up of larger galaxies. As a consequence, in the present universe both small and large galaxies...
The shear catalog is produced by the Fourier_Quad method, and well tested on the real data itself with the field-distortion effect. Our main approach is called quasi-2D as we do use the photo-zz information of each individual galaxy, but without dividing the galaxies into redshift bins. ...

Observations show a prevalence of high redshift galaxies with large stellar masses and predominantly passive stellar populations. A variety of processes have been suggested that could reduce the star formation in such galaxies to observed levels, includi
In the late 1960s and early 1970s there was a brief re-vival of the Lemaître models as a means of explaining why the preponder-ance of quasistellar objects (QSOs) had redshifts near z= 2, a value that will fall out of the models if these objects were emitting during the ...
