OTELO is a survey of emission-line objects that will be carried out using tunable filters with OSIRIS at the GTC. The survey will have a deep impact on...
Quantifying Star Formation Activity in the Inner 1 kpc of Local MIR Bright QSOs
We examine star formation activity in a distant (z 0.1) and flux-limited sample of quasars (QSOs). Midinfrared (MIR) spectral diagnostics at high spatial...
Radio emission during the formation of stellar clusters in M 33
Aims: We investigate thermal and nonthermal radio emission associated with the early formation and evolution phases of young stellar clusters (YSCs) selected by...
Radio Spectra and Star Formation Histories in HII Galaxies
A sample of actively star forming H II galaxies has been observed in the radio continuum and several optical bands. These galaxies are currently undergoing very...
Recent SFR calibrations and the constant SFR approximation
Aims: Star formation rate (SFR) inferences are based on the so-called constant SFR approximation, where synthesis models are required to provide a calibration...
Recent Star Formation in the Wolf-Rayet BCDG MRK 1094
We present preliminary results on high resolution Hα imaging of the Wolf-Rayet blue compact dwarf galaxy (BCDG) Mrk 1094. This galaxy presents a bar-shape...
Relative ages of Galactic globular clusters. Clues to the Milky Way formation time scales
Based on observations with the Advanced Camera for Surveys (ACS), I will present accurate relative ages for a sample of 64 Galactic globular clusters. This...
Relative lithium abundances in pre-main-sequence spectroscopic binaries
We present a study of the lithium abundance of five pre-main sequence (PMS) double-lined binaries. These binaries are composed of weak-lined T Tauri stars...
Resolving the kinematical structure within the nuclear starburst of NGC 253
We present high spectral and spatial resolution spectroscopy of the nuclear starburst region of the galaxy NGC 253. Two slit positions, matching the major and...
