    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...

    IMF variations in dwarf galaxies
    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...
  • Publication
    IMF variations in the Fornax cluster
    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...
  • Publication
    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...

    Impact of the Milky Way Galactic bar on stellar streams: the case of Hyades
    Tidal streams of disrupted clusters are powerful probes of the gravitational potential of the Galaxy, and are routinely detected in the stellar halo of the...
