The Formation of Galactic Bulges
Reynier Peletier, Marc Balcells, Jesus Falcon-Barroso +1
We summarise some recent results about nearby galactic bulges that are relevant to their formation. We highlight a number of significant advances in our understanding of the surfac…
Satellite Infall and the Growth of Bulges of Spiral Galaxies
M. C. Eliche-Moral, M. Balcells, J. A. L. Aguerri +1
For bulges of spiral galaxies, the concentration, or Sersic index, increases with bulge luminosity and bulge-to-disk ratio B/D (Andredakis, Peletier, & Balcells 1995, MNRAS, 275, 8…
Spheroid and disk signatures in galaxy bulges
Marc Balcells
Recent progress on the structure and dynamics of bulges is reviewed. Those aspects that link galaxy bulges either to oblate spheroids akin to elliptical galaxies or to rapidly-rota…
Nuclear Components in the Bulges of Disk Galaxies
M. Balcells, L. Dominguez-Palmero, A. Graham +1
By combining surface brightness profiles from images taken in the HST/NICMOS F160W and ground-based (GB) bands, we have obtained NIR profiles for a well studied sample of incli…
The Central kpc of Galaxy Bulges
M. Balcells
We study the innermost regions of bulges with surface brightness data derived from combined HST/NICMOS and ground-based NIR profiles. Bulge profiles to 1-2 kpc may be fit with Sers…
