*Scientific rationale: *
It is widely accepted that variability provides important information on the nature of the emission mechanisms and the geometry of the central source in Active Galactic Nuclei. This is an exciting time in the field of AGN variability, due to the wealth of new results produced in the last few years. This conference intends to focus on *radio-quiet* sources, discussing our current understanding of the central source variability across the IR, optical, and UV regimes up to hard X-rays, and the clues that variability provides about the physics and structure of the AGN phenomena. The contributions are intended to address the problem of AGN variability both from the observational and theoretical point of view, on short and long time scales, presenting results and expectations from wide-field/deep surveys, pointed observations, ground-based and space observatories.

The *topics* will include:

• X-ray flux and spectral variability
• UV emission/absorption variability, correlations and SED variability
• Variability on the optical band: reverberation, the continuum and the full sky surveys
• AGN variability analysis methods
• Variability constrains on theoretical models: from the MRI to the X-ray corona.

80 years ago, in spring 1933, Karl Jansky published his discovery of cosmic radio emission. This paved the way not only for a new discipline, radio astronomy, but also for an exploration of the universe that now encompasses almost the entire electromagnetic window.

Nowadays, radio astronomy is about to enter into yet another "golden era" with a number of new or upgraded radio facilities coming online and major new initiatives, like the SKA, are starting up. This conference will try to highlight the original and exciting science currently being produced by radio astronomical facilities, such as the Effelsberg telescope, the GBT, LOFAR, ALMA, the Karl Jansky VLA, eMERLIN, EVN, VLBA, as well as the pathfinder experiments of the Square Kilometre Array (SKA), and others.

The advanced science delivered by the radio astronomical community will improve our current knowledge of the universe, highlight new trends, and address key questions in modern astrophysics that may lead us to even more ambitious science goals to be targeted by future radio facilities like the SKA.

Science areas that will be discussed are among others: Cosmology, galaxy evolution, AGN and compact objects, star formation, interstellar medium, The Milky Way and Galactic science, radio transients, fundamental and astroparticle physics, extreme physics and associated theory. In particular:

• From the dark ages to cosmic large scale structure (EoR, dark energy, HI web)
• Galaxies and galaxy evolution (HI, radio continuum, magnetic fields)
• Stars and star formation (masers, radio stars, planetary radio emission, disks)
• Interstellar and Intergalactic Medium (physical processes in the ISM and IGM)
• Compact Objects (AGN, X-ray binaries, neutron stars, radio transients)
• Tests of fundamental physics (pulsars, fundamental constants)

The last Modern Radio Universe took place 2007 in Manchester commemorating 50 years of the Lovell telescope and looking forward towards the SKA. This issue of the conference commemorates the groundbreaking work of Karl Jansky 80 years ago and comes 40 years after the Effelsberg 100m telescope started operations.

The conference will consist of invited talks (approx. 20 min) and 15 min contributed talks (potentially a few 30 min review talks) plus posters. In short, combining past and future of radio astronomy, the main focus of the science presentations, will be to make an inventory of outstanding science results that are presently being obtained by the newly upgraded or constructed facilities.
