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...

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.

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.

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.

Electron-electron (e-e) collisions can impact transport in a variety of surprising and sometimes counterintuitive ways. Despite strong interest, experiments on the subject proved challenging because of the simultaneous presence of different scattering mechanisms that suppress or obscure consequences of e–e scattering. Only recently, sufficiently clean electron systems with transport dominated...

I will review the rapid recent progress made in modelling neutron stars in binary system and the associated gravitational-wave emission. In particular, I will discuss how our understanding on the maximum mass and radii of neutron stars has improved with the detection of GW170817. In addition, I will illustrate how the properties of magnetised accretion flows onto black holes represent the...

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.

The machine is in fact optimized for the study of the mass range of the charmonium-charm states, where several expected and unexpected bound states have been discovered in the last decade, the so-called XYZ states. BESIII was one of the main actors...

150 years ago Dmitrii Ivanovich Mendeleev (1834-1907), then a young chemistry professor in St. Petersburg, formulated his version of the system of elements. The choice of date is somewhat arbitrary, as there were five other attempts at periodic tables postulated earlier in the 1860s, some of which resemble our present version slightly more than Mendeleev’s in certain respects. Also, the main...

Our aim is to understand some conventional and non-conventional mesons by using an effective QFT models. Starting from a single $q\bar{q}$ seed state in the Lagrangian some states appear as a dynamically generated companion poles. We show that $K_0^* (700)$ is a companion pole of the heavier $K_0^* (1430)$ resonance, $X(3872)$ emerges as a virtual companion pole of $\chi_{c1} (2P)$, and the...
