The Peripheries of Nearby Galaxies: Dim but not Dull
Evidence is mounting for the presence of complex low surface brightness structures in the outer regions of galaxies. While the most spectacular examples are...
The role of massive black hole recoil in galaxy evolution
The coalescence of a massive black hole (MBH) binary leads to the gravitational-wave recoil of the system and its ejection from the galaxy core. We have carried...
The role of metals from molecular clouds to galactic discs
From the time the first stars formed to the present-day, metals have witnessed the assembly of structure in the Universe in great detail. Although metals only...
The Square Kilometre Array: At the Frontiers of Astronomy, Physics, and Astrobiology
The Square Kilometre Array is intended to be the centimeter- and meter-wavelength telescope for the 21st Century. Originally proposed as the "hydrogen telescope...
The star formation history of different types of dwarf galaxies
We are going to present a new code to derive the SFH of a complex stellar population system, like a galaxy. This code has been used to obtain the SFH of six...
The Star Formation History of Eridanus II: On the Role of Supernova Feedback in the Quenching of Ultrafaint Dwarf Galaxies
Eridanus II (Eri II) is an ultrafaint dwarf (UFD) galaxy (M V = -7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude...
The triggering mechanisms of powerful radio galaxies: mergers and interactions.
Despite speculation that both starburst and nuclear activity in galaxies may be intimately linked via the common triggering mechanism of mergers and...
The SAURON survey has revised our view of early type galaxies discovering that central disks and multiple kinematic components are common; 75% of the sample...
Transitions from Clumpy to Smooth Galaxies over Cosmic Time
Galaxies at redshifts z~2-5 are dominated by clumpy morphologies instead of the more familiar elliptical and spiral types seen in the local Universe. The clumpy...
