We quantify the energy radiated through all the collisional lines in a photoionized nebula in the presence of temperature fluctuations in the form of hot spots...
Enhancements over the electronic control for OSIRIS-Gtc Fabry-Perot tunable filters.
OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) is the optical Day One instrument for the 10.4m Spanish telescope GTC (Gran...
Enhancing WFIRST Science with the Addition of a Redder Filter
We outline a number of science advantages for adding a K or Ks filter (lambda_c 2.15 microns) and propose to extend the wavelength coverage for WFIRST into the...
Enigmatic Low-Velocity Jet-Like Features in Planetary Nebulae
We are developing a project aimed at studying the physical properties, origin and evolution of low-ionization structures in planetary nebulae. Within this...
Environmental dependence of the IMF-sensitive features in intermediate-mass quiescent galaxies
In this work, we investigate the impact of large-scale environment on the IMF in quiescent galaxies. For this purpose, we compare the trend of IMF-sensitive...
Environmental effects in the structural parameters of Coma galaxies
We have studied the quantitative morphology of the galaxies of the Coma cluster brighter than mr=17. The surface brightness profiles of all galaxies were...
Environmental effects on galaxy evolution in a z=5.2 proto-cluster
Galaxy clusters are the most massive gravitationally bound structures in the Universe and they play a key role in our understanding of structure formation and...
