Course content

Overview lectures: The standard cosmological model: The goal of these lectures is to summarise the current standard cosmological model, LambdaCDM?, and to present the main experimental proofs establishing its validity. I will go quickly through the main aspects of the Friedmann-Lemaitre model, of the thermal history of the universe after inflation, and of the theory of cosmological perturbations. There won't be time to enter into the detailed formalism, but I will try to stress the points that I find most useful for understanding the underlying physics. Next, I will summarise how the main observables (CMB and large scale structure spectra) depend on the parameters of the model. I will then review the observational probes of LambdaCDM?, and discuss to which extent this model is robust. The discussion will include recent Planck results and a review on what we know about the role of neutrinos in the universe.

Galaxy Clusters: I will describe how we observe, and characterize the properties, of the clusters of galaxies, the largest gravitationally-bound structures in the Universe. I will discuss how these observations are used to constrain both the parameters of the cosmological background in which galaxy clusters form and evolve, and the physics that rules the baryonic and dark matter components.

Galaxy Formation and Evolution: The aim of the lectures will be that of providing an introduction to the ideas and concepts that underpin modern models of galaxy formation and evolution, in a Universe in which cosmic structures originate from small initial perturbations and build up hierarchically. I will start with an overview of the basic observational results that our theory should reproduce. I will then focus on the physical processes at play. Finally, I will give a brief review of the numerical techniques that are currently used to study galaxy formation in a cosmological context, and will highlight their most recent successes and open problems.

Large Scale Structure of the Universe and New Physics: The Large Scale Structure (LSS) provides an unique laboratory to test our understanding of gravity, the properties of neutrinos, the nature of Dark Matter and Dark Energy, and the state of the primordial Universe. All these subjects involve physics beyond the Standard Model, and therefore one can see the LSS as potentially the best laboratory for New Physics for the years to come. In these lectures I will discuss how this program can be put into practice, focusing mainly on its theoretical aspects. After introducing the LSS observables and statistical description, I will review the dynamics of structure formation, from the initial conditions to the late evolution, and the theoretical tools to describe it. Then, I will discuss the impact on the LSS of various modifications of the standard LambdaCDM? scenario: massive neutrinos, warm dark matter, dynamical dark energy models, modifications of General Relativity. Finally, I will discuss the potential of present and future LSS observations to "discover" New Physics, and the work to be done to improve it.

Aim of the schoolclick to show

The school will cover topics relevant to the research subjects of the TRR33 network. The aim is to bring together observation and theory: "Theory for Observers & Observations for Theorists".

The school is part of a series, and was previously organized in 2007, 2008, 2009, 2010, 2011, 2012 and 2013.

Registration & fees

The registration deadline is on November 3rd, 2014.

To register, please fill in the form below. Please note that we will accept a limited number of participants (40).

There is a registration fee of ¤60 per person, to be paid by bank transfer to the school's account upon confirmation of acceptance. We will send the appropriate details at that stage.

If you need a visa to attend the school and require an official invitation letter, we recommend you to contact us as soon as you have confirmation of acceptance and definitely before October 1st, 2014.


TRR-33 members:

  • The TRR-33 will cover all travel expenses including the hotel and the registration fee, through the normal TRR33 travel funding of your group: ask your PI for permission
  • TRR-33 will NOT cover the food & beverage expenses (outside the hotel) because of DFG regulations. The only possibility for reimbursement of these expenses is through your local institute (university) funds. Ask your PI!

Non-TRR-33 participants:

  • Unfortunately, we will not be able to provide financial support to students this year. Please arrange for your own funding through your institution.

Location & accommodation

The school will take place in Passo del Tonale, Italy.


PLEASE NOTE that participants will be grouped in double rooms. No single rooms are available. You DO NOT have to book by yourself as we have already arranged for the rooms. Participants will then pay the hotel directly there (only those who require a VISA are asked to pay in advanced).

  • Prices:
    Double: ¤47 per person per day (half board)
      ¤39 per person per day (B&B)
    single room supplement: ¤8 per day
    full board supplement: ¤8 per day

  • Wi-Fi access will be available in the hotel lobby and lounge/bar although it can be somewhat unreliable. One card with five hours of internet access will be included in the participation fee. Further cards will be available for purchase at the hotel for ¤5 each.

Travel information

Suggested solutions

We will provide a bus from Trento train station to Tonale at about 7pm on Sunday, Dec 7st. Please arrive by 18:30 if you intend to use the bus and wait inside Trento main station (look for the TRR33 Winterschool sign). If your train/flight is delayed please contact the organizers.

You can reach Trento by train from Verona (about 1h), Venezia Marco Polo (about 2.30 h), or Innsbruck (about 3h). After the school on Friday, Dec 12th, there will be a bus transfer Tonale-Trento, departing from the hotel at 1pm.

NOTE: the cost of the bus transfer is NOT included in the registration fee. The actual cost will depend on how many people request the bus transfer, but should come to approximately ¤20. This will be payable together with the participation fee upon your being accepted.

If you miss the bus or you arrive on a different day, you can reach Tonale from Trento in this way:

  • Close to Trento FSS Station, there is the Trentino Trasporti Station (very close, just beside): take a little train from Trento to Malč (you can buy the ticket at the station).
  • From Malč take a bus to Tonale (the bus stop is outside Malč station, the ticket can be bought at the station). Malč is 30 km from Tonale.

Please check the time schedule of the train and bus between Trento and Malč:

* Train timetables

Note that a taxi Trento - Tonale directly is quite expensive (~¤150).

In order to find the most convenient connections to Venezia Marco Polo, Verona or Innsbruck you can visit the websites:,
