By isolating the red clump giant population in the color-magnitude diagrams and inverting their star counts, we can obtain directly the density distribution of...

We have undertaken a study of the nature of red galaxies at low and intermediate redshifts in the GOYA photometric survey. A new photometric index based on...

The Penn State - Torun Planet Search (PTPS) performed with the Hobby-Eberly Telescope is devoted to search and characterization of extrasolar planetary systems...

The mid-infrared camera and spectrograph CanariCam is one of the first light instruments to be operative at GTC. To exploit the CanariCam guaranteed observing...

Our analysis is based mainly on redshift data for 145 galaxies mostly acquired at the Telescopio Nazionale Galileo and on new photometric data acquired at the...

We present measurements for all objects for which we were able to derive secure redshifts. This includes galaxies belonging to the six aforementioned clusters...

EMIR, the near-infrared camera and multi-object spectrograph operating in the spectral region from 0.9 to 2.5 μm, has been commissioned at the Nasmyth focus of...

A photometric method to detect planets orbiting around shortperiodic binary stars is presented. It is based on the detection of eclipse-signatures in the...
