The necessity of dark matter in MOND within galactic scales
Ignacio Ferreras, Mairi Sakellariadou, Muhammad Furqaan Yusaf
To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sampl…
GOODS, UDF, and the evolution of early-type galaxies
I. Ferreras, T. Lisker, A. Pasquali +3
The HST/ACS images of GOODS-South have been used to select a sample of early-type galaxies, based on morphology and on the Kormendy relation. The classification scheme does not use…
Hot Cores : Probes of High-Redshift Galaxies
C. J. Lintott, S. Viti, D. A. Williams +2
The very high rates of second generation star formation detected and inferred in high redshift objects should be accompanied by intense millimetre-wave emission from hot core molec…
On the globular cluster formation history of NGC 5128
S. Kaviraj, I. Ferreras, S. -J. Yoon +1
We deduce the globular cluster formation history of the nearby elliptical NGC 5128 by using a phenomenological chemical enrichment model to reproduce its observed metallicity distr…
The role of outflows and star formation efficiency in the evolution of early-type cluster galaxies
I. Ferreras, J. Silk
A phenomenological model for chemical enrichment in early-type galaxies is presented, in which the process of star formation is reduced to a set of four parameters: star formation…
Imaging around PC1643+4631A at the Lyman limit
I. Ferreras, N. Benitez, E. Martinez-Gonzalez
We present a list of candidates for high redshift late-type galaxies in the field around the z=3.79 quasar PC1643+4631A. Deep U,V and R imaging has been used to search for objects…
