Image reconstruction with analytical point spread functions
Context. The image degradation produced by atmospheric turbulence and optical aberrations is usually alleviated using post-facto image reconstruction techniques...
Image sharpening of time-tagged counts from a photon counting detector - Application of a modified Wiener filter
A method for applying a modified Wiener filter to time-tagged single photon data is proposed which can preprocess the data for use by a wide range of image...
IMAGINE: a comprehensive view of the interstellar medium, Galactic magnetic fields and cosmic rays
In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. The purpose of the consortium is to coordinate and...
Imaging and Spectrophotometry of Markarian 1094: Implications for the Recent Star Formation
Narrowband Hα imaging and intermediate- and high-resolution optical spectrophotometry have been obtained for the blue compact dwarf Wolf-Rayet galaxy Mrk 1094...
Imaging the Elusive H-poor Gas in the High adf Planetary Nebula NGC 6778
We present the first direct image of the high-metallicity gas component in a planetary nebula (NGC 6778), taken with the OSIRIS Blue Tunable Filter centered on...
Imaging the Environment of a z = 6.3 Submillimeter Galaxy with SCUBA-2
We describe a search for submillimeter emission in the vicinity of one of the most distant, luminous galaxies known, HerMES FLS3, at z = 6.34, exploiting it as...
IMF and [Na/Fe] abundance ratios from optical and NIR spectral features in early-type galaxies
We present a joint analysis of the four most prominent sodium-sensitive features (Na D, Na I λ8190Å, Na I λ1.14 μm, and Na I λ2.21 μm), in the optical and near...
IMF radial gradients in most massive early-type galaxies
Using new long-slit spectroscopy obtained with X-Shooter at ESO-VLT, we study, for the first time, radial gradients of optical and near-infrared initial mass...
