Radial kinematics of brightest cluster galaxies by Loubser, S, Sansom, A, Sanchez-Blazquez, P, Soechting, I, Bromage, G

“…This is the first of a series of papers devoted to the investigation of a large sample of brightest cluster galaxies (BCGs), their kinematic and stellar population properties, and the relationships between those and the properties of the cluster. …”

Rejuvenation of spiral bulges by Thomas, D, Davies, R

“…We seek to understand whether the stellar populations of galactic bulges show evidence of secular evolution triggered by the presence of the disc. …”

Nuclear Properties of Nearby Spiral Galaxies from Hubble Space Telescope NICMOS imaging and STIS Spectroscopy by Hughes, M, Axon, D, Atkinson, J, Alonso-Herrero, A, Scarlata, C, Marconi, A, Batcheldor, D, Binney, J, Capetti, A, Carollo, C, Dressel, L, Gerssen, J, Macchetto, D, Maciejewski, W, Merrifield, M, Ruiz, M, Sparks, W, Stiavelli, M, Tsvetanov, Z

“…Using R-H and J-H colors and equivalent widths of H-alpha emission (from the STIS spectra) we investigate the nature of the stellar population with evolutionary models. Under the assumption of hot stars ionizing the gas, as opposed to a weak AGN, we find that there are young stellar populations (~10-20 Myr) however these data do not allow us to determine what percentage of the total nuclear stellar population they form. …”

Nuclear properties of nearby spiral galaxies from Hubble Space Telescope NICMOS imaging and STIS spectroscopy by Hughes, M, Axon, D, Atkinson, J, Alonso-Herrero, A, Scarlata, C, Marconi, A, Batcheldor, D, Binney, J, Capetti, A, Carollo, C, Dressel, L, Gerssen, J, Macchetto, D, Maciejewski, W, Merrifield, M, Ruiz, M, Sparks, W, Stiavelli, M, Tsvetanov, Z

“…Using R - H and J - H colors and equivalent widths of Hα emission (from the STIS spectra), we investigate the nature of the stellar population with evolutionary models. Under the assumption of hot stars ionizing the gas, as opposed to a weak active galactic nucleus (AGN), we find that there are young stellar populations (∼ 10-20 Myr); however, these data do not allow us to determine what percentage of the total nuclear stellar population they form. …”
