Ultra-deep Imaging: Structure of Disks and Haloes
Johan H. Knapen, Ignacio Trujillo
Deep imaging is a fundamental tool in the study of the outermost structures of galaxies. We review recent developments in ultra-deep imaging of galaxy disks and haloes, highlightin…
Relic galaxies: where are they?
Luis Peralta de Arriba, Vicent Quilis, Ignacio Trujillo +2
The finding that massive galaxies grow with cosmic time fired the starting gun for the search of objects which could have survived up to the present day without suffering substanti…
Ultra diffuse galaxies outside clusters: clues to their formation and evolution
Javier Román, Ignacio Trujillo
We identify six ultra diffuse galaxies (UDGs) outside clusters in three nearby isolated groups (z<0.026) using very deep imaging in three different SDSS filters (g, r and i bands)…
Testing the wavelength dependence of cosmological redshift down to
I. Ferreras, I. Trujillo
At the core of the standard cosmological model lies the assumption that the redshift of distant galaxies is independent of photon wavelength. This invariance of cosmological redshi…
The effect of environment on the structure of disc galaxies
Florian Pranger, Ignacio Trujillo, Lee S. Kelvin +1
We study the influence of environment on the structure of disc galaxies, using \texttt{IMFIT} to measure the g- and r-band structural parameters of the surface-brightness profiles…
Massive relic galaxies prefer dense environments
Luis Peralta de Arriba, Vicent Quilis, Ignacio Trujillo +2
We study the preferred environments of massive relic galaxies ( galaxies with little or no growth from star formation or merger…
