The last decade has seen an amazing transformation in our ideas about the central bulges of disk galaxies. We are probably only half-way through this change. In this talk I give an overview of three areas of my specific interest; all are presented as ingredients for further refining our concept of bulge. First, I discuss whether the inner few

We investigate the nuclear and global structure of early-type galaxies, and the apparent disparity between the Nuker and Sersic models for radial light profiles. We show that the so-called "power-law" galaxies in fact have Sersic r1/n profiles over their entire observed radial range. Consequently, only three (Sersic-profile) parameters are required

We report the discovery of a radio-quiet type 2 quasar (SDSS J165315.06+234943.0 nicknamed the `Beetle' at z = 0.103) with unambiguous evidence for active galactic nucleus (AGN) radio-induced feedback acting across a total extension of ˜46 kpc and up to ˜26 kpc from the AGN. To the best of our knowledge, this is the first radio-quiet system where

We present a multi-wavelength study of the gas dynamics and star formation in the grand-design spiral galaxy NGC 5248, illustrating how coupled dynamical mechanisms can generate spiral structures from tens of kpc to hundreds of pc, drive disk evolution, and fuel star formation on progressively smaller scales. Although to date NGC 5248 has been

We use long-slit spectra taken with the William Herschel Telescope on La Palma and high-resolution Hubble Space Telescope imaging to study the gas kinematic in the halo of the ultraluminous infrared/radio galaxy PKS1345+12 ( z=0.122). Our long-slit spectra show line splitting at the locations of massive star clusters ( 106
