New Cosmic Messengers: Gravitational-Wave Astronomy

Since the groundbreaking detection of gravitational waves in 2015 and the multi-messenger observation of a binary neutron star merger in 2017, gravitational-wave (GW) astronomy has progressed rapidly, yielding a wealth of scientific insights in astrophysics, cosmology, and fundamental physics. The international GW network, LIGO-Virgo-KAGRA, has already detected over two hundred sources, and efforts are underway to upgrade existing detectors and extend their astrophysical capabilities. In collaboration with Paris (STEP’UP) and Pisa Universities, these special lectures will focus on key topics in gravitational wave physics, designed to provide a solid foundation in the field.

Mornings will be dedicated to lectures while several afternoons will cover the discussion of foundational papers in the field. 

Topics covered include:

  1.  the configuration of interferometric detectors
  2. quantum squeezing techniques
  3. the challenges posed by low-frequency detection gravitational-waves for third-generation detectors (Einstein Telescope and Cosmic Explorer)
  4. multi-messenger astrophysics
  5. cosmology with gravitational waves.

When : March 16 to March 20 2026 – exact schedule below

Where : The courses will be conducted on Zoom.

These lectures upon completion will bring 3 points for your doctoral training program. Lectures are given in English.
