Astrostatistics is developing fast as astronomy is confronted to huge volumes of data. This constitutes undoubtly a new era through a move from object- to data-driven astrophysics. We can distinguish two types of challenges: the first one is related to the exploration of the data space and the second one is the physical interpretation of the results of this exploration. Astrostatistics cannot be reduced to the technical issues brought by methods and algorithms required to analyse the data. Despite these tools are not part of the cursus of astronomers, things are changing rapidly through schools, training sessions, collaborations with experts (statisticians) as well as developments of specific tools adapted to astronomical data. The use of new techniques pervades the astronomical literature. To convince more and more astronomers to switch to this new approach to do science, it is important to demonstrate the relevance of astrostatistics results.

The interplay between ubiquitous dust, ice and gas in space knits an interesting tale from collapsing interstellar clouds to the formation of new stars, planets, moons and comets. Along this path, the formation of complex organic molecules necessary to construct the building blocks of life brings us a step closer to the understanding of the evolution of life. The advancement in the understanding of these vast intricacies of space lies in the development of varied laboratory techniques and astrophysical modelling in close connection with space exploration and astronomical observations. We are living a very exciting time at the interplay between current and future missions/facilities. Return of extra-terrestrial samples is one of the drivers of these missions (e.g. Hayabusa 2, OSIRIS-Rex) together with a more and more detailed exploration of the Solar System planets, moons and other bodies (e.g. Martian rovers ExoMars and Mars 2020, BepiColumbo for Mercury, the future JUICE and Europa Clipper missions for Jupiter and its moon Europa). From the astronomical side, new perspectives arise from progress in high angular resolution observations from the optical/infrared (VLT and the coming JWST and ELT) to the sub-mm/mm range (ALMA, NOEMA) to the mid-radio frequencies (SKA) together with a better coverage of the electromagnetic spectrum (e.g. ATHENA for X-rays) and the discovery of new exo-worlds (e.g. PLATO, ARIEL). The ECLA 2020 conference will provide the opportunity for interdisciplinary exchanges between scientists active in different research fields, which range from astronomy to geology and from chemistry to instrumentation. These interactions will foster collaborations that will result in better scientific exploitation of missions/facilities in planetology and astronomy in relation with the major questions on our origins.

The LSST project is moving forward in the construction phase, and activities in the LSST Science Collaborations (Solar System; Stars, the Milky Way and Local Volume; Transients and Variable Stars; Galaxies; AGN; Strong Lensing; Dark Energy and Informatics and Statistics) are vibrant and involve a significant European participation.

The ICSLS (InternationaI Conference on Spectral Line Shapes) bi-annual conference series started in Paris, France in 1973, and it is held alternating European and North-American locations. The last three editions were held in Tullahoma, Tennessee, USA (2014), Torun, Poland (2016) and Dublin, Ireland (2018). The 25th ICSLS conference is organized by the Department of Mathematics and Physics, University of Campania Luigi Vanvitelli. It will be held inside the wonderful Monumental Complex of Belvedere di San Leucio, in Caserta (Italy). Also known as Ferdinandopoli, its construction is due to king Ferdinand IV of Bourbon, who wished to create a small village around the silk factory, in the eighteenth century. The ICSLS 2020 conference covers a broad range of topics related to spectral line shape studies, including: line shapes of atomic and molecular transitions in neutral gaseous mixtures, fundamental metrology, single and multi-photoionisation processes, high and low temperature plasmas, clusters and helium droplets, nanophotonic processes, spectroscopy of stellar atmospheres and interstellar media, spectroscopy of planetary atmospheres and exoplanets, cold atoms and molecules, collision-induced spectra, processes in laser fields, innovative techniques of line shape applications for diagnostic purposes and fundamental studies with narrow optical resonances, along with applications in e.g., industrial, environmental, medical and all other potential domains of interest. The conference will include a mix of invited lectures, contributed talks and poster presentations.

In the last decade, increasingly strong efforts have been devoted to understand the role of active galactic nuclei (AGN) during the cosmic evolution of galaxies, groups and clusters of galaxies. Chandra, XMM-Newton, and Hitomi have unveiled spectacular interactions of the central supermassive black hole (SMBH) with the host atmosphere in the form of resolved X-ray cavities, shocks, metal uplifts, and turbulence. At the same time, the hot halos of galaxies, groups, and clusters recurrently condense in localized regions forming multiphase filaments and clouds that rain onto the central SMBH and that are detected via optical/IR/radio telescopes (e.g., HST, Magellan, VLT, IRAM, SOFIA). In the nuclear region, spectroscopical studies of AGN have discovered an amazing diversity of feeding and feedback phenomena, including ultrafast outflows, warm absorbers, massive ionized, neutral and molecular outflows. With the advent of next-generation telescopes (e.g., ALMA, MUSE, JWST, XARM, Athena, LOFAR/SKA), we are starting to learn that multiphase outflows are an ubiquitous phenomenon in cosmic structures of different masses and ages. Linking the macro to micro scales — and vice versa — of feeding and feedback processes is thus vital to advance our knowledge on the (co)evolution of black holes, galaxies, and clusters of galaxies. The aim of the workshop is to bring together active researchers in the above tightly related — but often disjointed — fields in order to discuss the latest results, confront state-of-the-art simulations/models and observations, as well as promote new collaborations and set the path to future observational and numerical campaigns.

The discovery of multiple stellar populations in globular clusters (GCs) represents one of the most important results of the research in the field of stellar astrophysics. The last two decades witnessed a growing number of studies which, by reversing our vision of simple stellar systems compatible with an isochrone, unveiled the complex nature of the GCs . High-precision photometry color-magnitude diagrams revealed that GCs are composed of two or more discrete stellar groups with specific chemical compositions: one with abundances typical of halo field stars, the other(s) with enhanced light-elements as nitrogen and sodium. A sub-group of clusters also exhibits variations in heavy-elements and iron. Several scenarios of formation and evolution of multiple stellar populations have been proposed so far but none of them fulfills at once all the numerous observational constraints. Important questions, therefore, are still open: How did GCs form in the early Universe? What is their role in the assembly of the Galaxy? Did they significantly contribute to the reionization of the Universe? The aim of this conference is to connect observation and theory to review the state-of-the-art on multiple populations in GCs and discuss the developments of GC studies in the next future.

"The 9th Microquasar Workshop: Celebrating over 50 years of discovery" will be held in Cagliari (Sardinia), Italy, on 21-25 September 2020. It is the ninth in a series of conferences mainly devoted to microquasars but also covering relativistic jet sources in a broader context. It will also be an occasion to celebrate the 50 years since the discovery of variable radio emission from X-ray binaries. The workshop aims to present and discuss the latest results related to X-ray binaries, in particular accretion/ejection physics (multi-wavelength observations and theory/simulations), the properties, mechanisms and interplays of the accretion disk, disk winds, jets, accretion/ejection at all scales, and comparison with the various accretions (BH, NS, CV). The formation, evolution and merging of compact objects in binaries will also be addressed. In the context of recent missions devoted to transient sources, new facilities will be discussed (such as NICER, HXMT, MeerKAT, ASKAP, etc), in addition to new tools and diagnostics based on X-ray timing.
