The galaxy life-cycle. From activity to quiescence, and back, across cosmic times

Venice, Italy, 24-28 October 2016
Scientific rationale
The mechanisms driving the shutdown of the star formation activity in galaxies, the so called ’quenching’,
remains one of the least understood puzzles in galaxy formation to date. It is well established that the efficiency
of a galaxy in forming stars is based on a delicate balance between cold gas inflow and outflow. Several
quenching mechanisms have been proposed, which act to either prevent  the accretion of new cold material
onto the galaxy or remove the gas reservoir from it. Which quenching process or which combination of processes
is driving the observed shutdown, is still an open question.
The aim of the conference is to challenge the current theoretical framework with the results of the most recent
observations and to let theoreticians and observers discuss extensively in order to answer the following key
  • Is there a compelling observational evidence of gas inflow onto galaxies?
  • How are inflow and outflow interplaying to set the galaxy gas content and star formation activity?
  • What is the current view on the galaxy gas content from neutral and molecular gas surveys? Is there a clear relation to the environment?
  • What is the role of cold/hot accretion in sustaining/suppressing the SF activity during the structure formation process?
  • Which evidence for quenching are providing the main galaxy scaling relations, such as star forming galaxy Main Sequence, mass-metallicity relation, morphology-density relation? What can we infer about the evolution of the galaxy star formation activity?
  • What are the main quenching mechanisms. and which mechanism is most efficient at which halo or stellar mass scale?
  • What is the major physical link between morphology, environment, mass and star formation activity?
  • How disk instability and compactness are driving the morphological evolution of galaxies and their level of star formation activity across cosmic time?

 The venue of the conference is the enchanted Franchetti Palace on the Grand Canal of Venice. The great fifteenth-century palazzo overlooking the Grand Canal was purchased by the Istituto Veneto di Scienze, Lettere e Arti as a venue for cultural activities such as conferences and art exhibitions. The building is located just off the Academy bridge and develop towards Campo Santo Stefano, in the center of the vast area where many of the leading Venetian cultural, such as the La Fenice Theather, Grassi Palace and Punta della Dogana, the Peggy Guggenheim Collection, the Academy Gallery, Fortuny Palace, Ca ‘Rezzonico and the Conservatorio Benedetto Marcello.
