TalkGalaxy structures and merging from 0.2 < z < 6
We examine the latest results concerning the evolution in the structures of galaxies from the local universe up to z ~ 6. We present results from the COSMOS...

TalkGravitational Lensing as Cosmological Tools
Gravitational lensing is a powerful astrophysical tool which allow us to studythe dark sector of the universe. Some of these applications include from thestudy...

TalkHow to use a cosmological N-body simulation as a theoretical model
A key problem that we are facing in cosmology nowadays is that we cannot make accurate predictions with our current theoretical models. We have all of the...

TalkHow well does galaxy clustering constrain cosmology?
On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

TalkImfit: A fast, flexible new program for fitting galaxy images
I will discuss a new, open-source astronomical image-fitting program, specialized for galaxies, which is fast, flexible, and highly extensible. A key...

TalkInflation and the CMB
In this talk I will review the subject of cosmological inflation, a period of early accelerated expansion. I will discuss Friedmann-Robertson-Walker cosmology...

TalkIs Dark Matter the most valid explanation for the mass which is apparently missing in the Universe?
Two main families of models explain that, at least in appearance, something like 90% of the mass of the Universe is still undetected. One (supported by an...

TalkLarge scale structures and galaxy evolution in the COSMOS Survey
The COSMOS survey is the largest high redshift galaxy evolution survey ever done -- imaging 2 square degrees with all major space-based and ground based...
