Stellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...

متن کاملStellar Populations in Active Galaxies
The role of stars and starbursts in AGN has been a recurring issue for nearly as long as AGN have been recognized as hosts of interesting phenomena. The heated “starburst versus monster” controversy of the 80’s and 90’s was gradually replaced by “starburst plus monster” studies, as observational work in the past decade has firmly established that accretion onto a super-massive black-hole and st...
متن کاملThe stellar populations of spiral galaxies
We have used a large sample of low-inclination spiral galaxies with radially-resolved optical and near-infrared photometry to investigate trends in star formation history with radius as a function of galaxy structural parameters. A maximum likelihood method was used to match all the available photometry of our sample to the colours predicted by stellar population synthesis models. The use of si...
متن کاملThe first galaxies: structure and stellar populations
The Hubble Deep Fields continue to be a valuable resource for studying the distant universe, particularly at z > 2 where their comoving volume becomes large enough to encompass several hundred L∗ galaxies or their progenitors. Here I present recent results from a near–infrared imaging survey of the HDF–North with NICMOS, which provides structural and photometric information in the optical rest ...
