In ATel #1599; Krimm et al. report a gradual brightening and softening of SWIFT J1753.5-0127's X-ray emission, using the SWIFT satellite on June 30, 2008. We performed contemporaneous BVRI imaging of the system with the IAC80 telescope at the Observatorio del Teide, Tenerife around T2300, 29 June and 02 July, 2008. We find average magnitudes: B=17

Context: Local reductions of the stellar velocity dispersion in the central regions of galaxies are known as sigma-drops (σ-drops). Knowing the origin of these features can lead to better understanding of inner galactic dynamics. Aims: We present a sample of 20 σ-drop galaxies matched with a control sample of galaxies without σ-drop in order to

We evaluate the nature of bulges in the Hubble sequence, based on an analysis of 216 disk galaxies of all morphological types (S0-Sd). For this purpose we collect our various analysis made separately for early and late-type galaxies, published in a series of papers. Using the criteria by Kormendy & Kennicutt we find strong evidence of pseudobulges
