The description of the Imaging Magnetograph eXperiment (IMaX) is presented in this contribution. This is a magnetograph which will fly by the end of 2006 on a...
IMF and Velocity-Dispersion Effects on Optical Spectroscopic Absorption Features
We explore the behaviour of the most popular spectroscopic absorption features in the optical region as a function of the initial mass function (IMF), while...
Dwarf galaxies tend to have a large spread in metal abundances and overall lower metallicites than large Spiral or Elliptical ones. Here we propose that if all...
The stellar initial mass function (IMF) is a fundamental ingredient in stellar population synthesis models and for decades it was considered to be universal...
Impact at the astronomical Observatory of Roque de los Muchachos from the Cumbre Vieja 2021 volcanic eruption at La Palma.
Between September 19 and December 13, 2021 a strombolian volcanic eruption took place on the island of La Palma. The main edifice was appeared at an altitude of...
Impact of environment on molecular gas reservoirs probed in distant cluster and field galaxies
It is clear that galaxies in local clusters are different from those in the field. Environment must play an important role in shaping the ensemble of galaxies...
Impact of Exoplanet Science in the Early Twenty-First Century
The impact of exoplanet science at the beginning of the twenty-first century is studied from two different approaches: the impact in astronomical science both...
Impact of Low-Frequency p Modes on the Inversions of the Internal Rotation of the Sun
We used the m-averaged spectrum technique ("collapsogram") to extract the low-frequency solar p-mode parameters of low- and intermediate-angular degrees (l ≤ 35...
Impact of proposed observing modes on the Spanish 10-m Telescope
The Instituto de Astrofisica is finalizing the design for a 10 m class optical/infrared telescope at the Observatory Roques de los Muchachos, La Palma. It is...
