Autor: González-Morán, A. L., Haro, P. Arrabal, Muñóz-Tuñón, C., Rodríguez-Espinosa, J. M., Sánchez-Almeida, J., Calhau, J., Gaztañaga, E., Castander, F. J., Renard, P., Cabayol, L., Fernandez, E., Padilla, C., Garcia-Bellido, J., Miquel, R., De Vicente, J., Sanchez, E., Sevilla-Noarbe, I., Navarro-Gironés, D.

We present an application of unsupervised Machine Learning Clustering to the PAU Survey of galaxy spectral energy distribution (SED) within the COSMOS field. The clustering algorithm is implemented and optimized to get the relevant groups in the data

Discovery of faint double-peak Halpha emission in the halo of low redshift galaxies

Autor: Almeida, J. Sanchez, Calhau, J., Munoz-Tunon, C., Gonzalez-Moran, A. L., Rodriguez-Espinosa, J. M.

Aiming at the detection of cosmological gas being accreted onto galaxies of the local Universe, we examined the Halpha emission in the halo of 164 galaxies in the field of view of the Multi-Unit Spectroscopic Explorer Wide survey (\musew ) with obser
