      The QCD equation of state from Heavy ion collisions and neutron star mergers: Physics Department - Aula Amaldi (Marconi Building)

      In this talk I will give a short overview on the current status and challenges in the exploration of dense QCD matter. While in relativistic heavy ion collisions, experiment and theory have been struggling for three decades to get a quantitative understanding of the QCD phase diagram. Only recently, new experimental programs allowed for significant progress. At the same time, the observation of gravitational waves from binary neutron star mergers has opened new venues in the study of dense QCD matter. Based on state-of-the-art models from both communities I intend to show the areas of overlap and opportunities for HIC and BNSM (with a short detour to core-collapse supernovae). In addition I plan to discuss open challenges and give some comments on what we can expect to learn from BNSM and what we should not expect to learn.

      We discuss recent calculations investigating the detailed
      impact of various "non-nucleonic" degrees of freedom in neutron star
      mergers. Pions are neglected in equation of state tables for merger
      simualtions but might actually occur in neutron star matter. We quantify
      their potential impact on the obseravbles of neutron star mergers. We
      describe a weak but potentially measurable signature of hyperons in
      neutron star mergers. Finally, we discuss the effects of deconfined
      quark matter.

      Piazzale Aldo Moro, 5 · 06 49911 Rome (Italy)

      I will discuss two aspects of the quantum fluctuations of vacuum spacetime that can be probed in gravitational wave (GW) observatories. The first is the quantum fluctuations near the horizon that lead to (stimulated) Hawking emission (a.k.a. echoes) AND multipolar deformation of Kerr geometry. The second is an irreducible noise in the GW detectors due to the quantum fluctuations of spacetime geometry. These are both (potential) manifestations of a UV/IR coupling that is inevitable in any non-perturbative theory of quantum gravity.

      Pulsar timing arrays are sensitive to low-frequency gravitational waves with periods of months to decades. They do so by precisely timing a collection of millisecond pulsars, whose extremely stable rotation makes them ideal for measuring perturbations in spacetime. Gravitational waves induce correlations in the pulse arrival times that follows a characteristic pattern known as the Hellings-Downs curve. Recently, pulsar timing array experiments around the world published the first evidence of nanohertz gravitational waves in the form of a gravitational wave background. In this talk, I will discuss how pulsar timing arrays detect gravitational waves, how we construct pulsar timing arrays, and describe recent results from the NANOGrav collaboration and the International Pulsar Timing Array (IPTA) collaboration.

      The success of the LCDM standard model of cosmology has now been established across a wide range of scales. Yet, despite this incredible success the precise nature of its ingredients has so far remained elusive.
      To this end, in the past decades a vast experimental effort has been undertaken to measure observables in the local and distant universe to unprecedented precision. These promising measurements have only deepened the mysteries of cosmology, however, as they revealed a growing tension between the current expansion rate of the Universe (specified by the Hubble constant) measured through the local distance ladder and that inferred from the cosmic microwave background. Now that the formal significance of this discrepancy has reached a level of five sigma significance, it is crucial to thoroughly re-examine the astrophysical observations at the heart of this Hubble tension. Similarly important is the role of looking at the future experimental efforts that are certain to bring striking new evidence that will help us to solve this cosmic puzzle.

        New probe for non-Gaussianities with primordial black hole induced gravitational waves

        We propose a new probe of primordial non-Gaussianities through
        the observational window of gravitational waves (GW) being induced by
        ultra-light ($M_{\text{PBH}}< 10^{9}\rm{g}$) primordial black holes
        (PBHs). An existence of primordial non-Gaussianity can leave imprints on
        the clustering properties of PBHs and the spectral shape of the induced
        GW signal. Focusing on local-type non-Gaussianities, we find a
        distinctive double-peaked GW energy spectrum which, depending on the PBH
        mass $M$ and the initial PBH abundance at formation time, i.e.
        $\Omega_\mathrm{PBH,f}$, can lie within the frequency bands of
        forthcoming GW detectors, including LISA, ET, SKA and BBO, hence
        rendering this signal promisingly detectable by GW experiments and
        promoting it as a novel portal probing non-Gaussianities. Moreover, by
        accounting on BBN bounds on the non-Gaussian GW amplitude we set
        model-independent constraints on the effective $\tau_\mathrm{NL}$,
        denoted as $\bar{\tau}_\mathrm{NL}(k)$, on scales
        $k>10^5\mathrm{Mpc}^{-1}$, which read as $\bar{\tau}_\mathrm{NL}(k) \mathcal{P}_{\cal R}(k) < 2\times 10^{-20} \Omega^{-17/9}_\mathrm{PBH,f} \left( \frac{M_{\rm PBH}}{10^4\mathrm{g}} \right)^{-17/9}$, where
        $\mathcal{P}_{\cal R}(k)$ is the primordial curvature power spectrum.

      • Input from HIC still active area of research – „known“ constraints may change in the future due to new experimental results
      • Need continuous exchange between communities
      • Input from nuclear structure and atomic physics
      • Similarly how can more interaction be encouraged?
      • General questions:
      • How can we get to a honest and realistic estimate of the systematic errors from: • EoS constraints from HIC
      • Nuclear structure calculations
      • BNSM simulations themselves
      • Is there any “new” type of input from NP or AP which can help improving the GW predictions?
