Morphology across cosmic time: assessing the evolution and interplay of disk and bulge-dominated galaxies in the CANDELS survey
Vitor M. Sampaio, Igor Kolesnikov, Reinaldo R. de Carvalho +2
We investigate the redshift evolution of disk and bulge-dominated galaxies using a mass-complete sample of 14,000 galaxies from the CANDELS survey, selected with $H_{\rm mag}…
Probing the major driver of stellar population properties over sub-galaxy scales with SDSS MaNGA IFU spectroscopy
Ignacio Ferreras, Marina Trevisan, Ofer Lahav +2
Thanks to Integral Field Unit survey data it is possible to explore in detail the link between the formation of the stellar content in galaxies and the drivers of evolution. Tradit…
Knowing when to stop
Ofer Lahav, Joseph Silk
When do we stop an ongoing science project to make room for something new? Decision-making is a complex process, ranging from budgetary considerations and tension between ongoing p…
Galaxy formation
Joseph Silk, Arianna Di Cintio, Irina Dvorkin
Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters,…
Exploring the Star Formation History of Elliptical Galaxies: Beyond Simple Stellar Populations with a New Estimator of Line Strengths
Ben Rogers, Ignacio Ferreras, Reynier F. Peletier +1
(Abridged) We study the stellar populations of 14 elliptical galaxies in the Virgo cluster. We propose an alternative approach to the standard side-band method to measure equivalen…
The formation history of the Galactic bulge
I. Ferreras, R. F. G. Wyse, J. Silk
The distributions of the stellar metallicities of K giant stars in several fields of the Galactic bulge, taken from the literature are compared with a simple model of star formatio…
On breaking the age-metallicity degeneracy in early-type galaxies: Outflows versus Star Formation Efficiency
I. Ferreras, J. Silk
A simple model of chemical enrichment in cluster early-type galaxies is presented where the main parameters driving the formation of the stellar component are reduced to four: infa…
Quasars and Galaxy Formation
Joseph Silk, Martin J. Rees
The formation of massive black holes may precede the epoch that characterises the peak of galaxy formation, as characterized by the star formation history in luminous galaxies. Hen…
