Schwarzschild orbit-based dynamical models are widely used to uncover the internal dynamics of early-type galaxies and globular clusters. Here we present for...
Origin of E+A galaxies - I. Physical properties of E+A galaxies formed from galaxy merging and interaction
We investigate the structural, kinematical and spectrophotometric properties of `E+A' galaxies - those with strong Balmer absorption lines but no significant...
Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II)...
Origin of the X-ray background and AGN unification: new perspectives
We critically review the basic assumptions of the standard model for the synthesis of the X-ray background (XRB) in the light of new data from ultradeep surveys...
OSIRIS Tunable Filter Imaging of the Large Scale Shock in Stephan's Quintet
We present preliminary OSIRIS Hα, [NII] and [SII] images and line-ratios on the large-scale shock (about 40 kpc long) discovered in the most popular compact...
OSIRIS (Optical System for Imaging and low/intermediate-Resolution Integrated Spectroscopy) will be one of the Day One instruments for the Spanish 10.4m...
OTELO survey: deep BVRI broad-band photometry of the Groth strip. I. Number counts and two-point correlation functions
Context: The Groth field is one of the sky regions that will be targeted by the OTELO (OSIRIS Tunable Filter Emission Line Object) survey in the optical 820 nm...
OTELO Survey: Deep BVRI Broadband Photometry of the Groth Strip. II. Optical Properties of X-Ray Emitters
The Groth field is one of the sky regions that will be targeted by the OSIRIS Tunable Filter Emission Line Object survey in the optical 820 nm and 920 nm...
OTELO (OSIRIS Tunable Emission Line Object Survey) is the GTC Key Project that will allow an optimal exploitation of the Spanish Day One GTC instrument OSIRIS...
