Cosmology with Gaussian process: inferring late-time expansion, implications for H0 and q0. (RINVIATO A DATA DA DEFINIRE)
- Sandeep Haridasu (Universtita di Tor Vergata)
11:30 - 12:30
Room: aula 412 GP has been a popular “model-independent” method, utilised to reconstruct the low-redshift cosmic expansion history, henceforth the dynamics of the late-time evolution. In this talk, I will present an extension of the standard Gaussian Process formalism, the Multi-Task GP with the ability to perform joint learning of several “low-redshift” cosmological data and on the robustness of several assumptions involved. Utilising the ``low-redshift'' expansion-rate we obtain constraints on H0 = 68.52 +- 0.94 (stat) +- 2.51 (sys) km/s Mpc^-1 and a corresponding rd = 145.61 +- 2.82 (stat) +- 4.3 (sys) Mpc. Subsequently, one can further constrain $q_0 = -0.52 \pm 0.06$ and the transition redshift zT = 0.64^{+0.12}_{-0.09}. Using the Om(z) diagnostic, we find that the concordance model is very consistent within the redshift range z<=2 and mildly discrepant for z>2. While GP provides flexibility, it can also lead to biases and incorrect inferences which become more apparent, for higher order derivatives.

15:00 Performances of Lobster Eye Optics and Their calculation. - Vladimir Tichy (Leicester University)
Performances of Lobster Eye Optics and Their calculation.
- Vladimir Tichy (Leicester University)
15:00 - 16:00
Room: Aula 300 -- Blocco C The grazing incidence lobster eye X-ray optics is introduced. The main advantage of this concept is large field of view. Two methods of calculation of its performances are presented. First, it is a numerical method based on simplified ray-tracing. The other method is an analytical method of direct calculation of effective collecting length. Results of tests of lobster eye prototypes are shown.

A view of the ProtoDUNE Single-Phase experiment at the CERN Neutrino Platform
- Enrico Gamberini (CERN Fellow)
15:00 - 16:00
Room: Aula 300 Blocco C After some years of planning and two intense years of engineering, fabrication, assembly, installation, and as much commissioning as feasible, the prototype for the single-phase liquid argon detector for the DUNE experiment, ProtoDUNE SP, has been completed, and has been exposed to beam from a new SPS beam line during Fall 2018. I will give some examples of the technical challenges addressed by this, the largest liquid argon time projection chamber ever constructed, the solutions adopted, and some initial data on some aspects of the performance of the apparatus.

Atomic scale metrology
- Enrico Massa (Istituto Nazionale di Metrologia)
16:30 - 17:30
Room: Aula 300 The activity is focused on the measurement of the (220) lattice plane spacing of silicon by means of combined optical and X-ray interferometry - COXI, which is one of the most advanced tools for atomic-scale displacement metrology. The aim is to determine the spacing of the (220) lattice planes in silicon to within 1 ppb relative uncertainty.

GW170817: lessons from the first observation of a binary neutron star merger
- Michal Bejger, (Nicolaus Copernicus Astronomical Center (CAMK), Warsaw.)
14:30 - 15:30
Room: 416 Blocco C The historically first detection of gravitational waves from a binary neutron star merger turned out to be a treasure trove for the dense matter physics, relativistic astrophysics, testing the theories of gravity and to emerging multi-messenger astronomy. I will summarize the multi-messenger results related to the GW170817 event, discuss implications of this observation and the future outlook.

14:30 From multi-messenger observations to the neutron stars equation of state - Margherita Fasano (Universita` di Roma)
From multi-messenger observations to the neutron stars equation of state
- Margherita Fasano (Universita` di Roma)
14:30 - 15:30
Using a Bayesian approach, we combine measurements of neutron star macroscopic observables obtained by astrophysical and gravitational observations, to derive joint constraints on the equation of state (EoS) of matter at supranuclear density. In our analysis we use two sets of data: (i) the masses and tidal deformabilities measured in the binary neutron star event GW170817, detected by LIGO and Virgo; (ii) the masses and stellar radii measured from observations of nuclear bursts in accreting low-mass X-ray binaries. Using two different parametrizations of the equation of state, we compute the posterior probability distributions of the EoS parameters, using which we infer the posterior distribution for the radius and the mass of the two neutron stars of GW170817. The constraints we set on the radii are tighter than previous bounds.

Fluorescenza X per medaglioni metallici rinascimentali
- Ferruccio Petrucci (FE)
15:00 - 16:00
I medaglioni rinascimentali raffiguranti gli imperatori romani Nerone e Vespasiano, che adornano il Palazzo Properi Sacrati, in Corso Ercole d’Este, a Ferrara, sono stati duplicati e venduti tanto tempo fa. Una coppia di medaglioni è stata rinvenuta presso un collezionista, che ha chiesto autorizzazione all’esportazione al fine di venderli all’asta. La tecnica XRF è stata usata per identificare i medaglioni autentici e le copie e le sorprese non sono mancate.

Spettroscopia per Immagini per la conservazione dell’Arte Contemporanea
- Ferruccio Petrucci (FE)
14:30 - 15:30
Il problema della conservazione di opere d’arte è particolarmente sentito per i manufatti di Arte Contemporanea, che, realizzati con i materiali più diversi, sembrano refrattari alle consolidate prassi di conservazione e persino di diagnostica. La Spettroscopia per Immagini, nata negli anni 90 con la grande diffusione degli apparecchi di imaging elettronico, si candida come diagnostica di elezione per questo e altri casi: vedremo perchè.
