PublicaciónObservational evidence for triaxiality, and for relatively recent star formation in the bulge of NGC 4736
CCD maps are presented of the inner 1.4 kpc of NGC 4736 in the B, V, R, I and Z bands, along with an ellipticity analysis of these, in which the ellipticities...

PublicaciónPhotometric observations of the warped disks of NGC 4013, NGC 4565 and NGC 6504
Three spiral galaxies with warped disks have been observed; NGC 4013, NGC 4565, and NGC 6504. There is a clear wavelength dependence in the warp's curve, the...
