The origin of the IR emission of low-luminosity AGN
To test recent suggestions that the infrared emission of low-luminosity AGN arises in a truncated thin accretion disk, we compare recent, high-resolution IR...
The origin of the light distribution in spiral galaxies
We analyse a high-resolution, fully cosmological, hydrodynamical disc galaxy simulation, to study the source of the double-exponential light profiles seen in...
The origin of the LMC stellar bar: clues from the SFH of the bar and inner disc
We discuss the origin of the Large Magellanic Cloud (LMC) stellar bar by comparing the star formation histories (SFHs) obtained from deep colour-magnitude...
The origin of the mid-infrared nuclear polarization of active galactic nuclei
We combine new (NGC 1275, NGC 4151, and NGC 5506) and previously published (Cygnus A, Mrk 231, and NGC 1068) sub-arcsecond resolution mid-infrared (MIR; 8-13 μm...
As part of a systematic effort to characterize the properties and progenitors of the most luminous planetary nebulae (PNe), we obtained a sample among the...
The Origin of the Relation between Metallicity and Size in Star-forming Galaxies
For the same stellar mass, physically smaller star-forming galaxies are also metal richer. What causes the relation remains unclear. The central star-forming...
The Origins of Planetary Nebulae in the Inner and Outer Disks of M 31
The planetary nebulae (PNe) of M 31 are receiving considerable attention as probes of its structure and chemical evolution in a galactic environment that is...
The origins of post-starburst galaxies at z < 0.05
Post-starburst galaxies can be identified via the presence of prominent Hydrogen Balmer absorption lines in their spectra. We present a comprehensive study of...
The OTELO Project is an extragalactic survey under way using the tunable filters of the instrument OSIRIS at the GTC. OTELO is already providing the deepest...
