Searching for emission-line galaxies: The UCM survey
We are carrying out a long-term project with the main purposes of finding and analyzing low metallicity galaxies. A very small number of very low metallicity...
Searching for emission-line objects in external galaxies
We are carrying on several surveys in nearby galaxies aiming to find, catalogue and study old and young emission-line objects as H II regions, Planetary Nebulae...
Searching for filaments and large-scale structure around DAFT/FADA clusters
Context. Clusters of galaxies are located at the intersection of cosmic filaments and are still accreting galaxies and groups along these preferential...
Distant clusters of galaxies provide a powerful method to study the formation and evolution of galaxies, and large scale structure of the Universe. However, the...
Searching for molecular gas inflows and outflows in the nuclear regions of five Seyfert galaxies
Active galactic nucleus (AGN) driven outflows are believed to play an important role in regulating the growth of galaxies, mostly via negative feedback. However...
Searching for star-forming galaxies in the Fornax and Hydra clusters
Context. The formation and evolution of dwarf galaxies is relatively difficult to understand because of their faint emission in all regimes that require large...
Searching for the orbital period of the ultraluminous X-ray source NGC 1313 X-2
We analysed the longest phase-connected photometric data set available for NGC 1313 X-2, looking for the ˜6-day modulation reported by Liu et al.. The folded B...
Searching for Tidal Remnants in the Milky Way: Photometric Survey of Globular Clusters
The picture of building the Milky Way halo from the merger of protogalactic fragments is considered the local manifestation of the hierarchical galaxy formation...
Secondary halo bias through cosmic time. I. Scaling relations and the connection with the cosmic web
Context. The spatial distribution of dark matter halos carries cosmological and astrophysical information. Cosmological information can be considered to be...
