In the ALMA 2030 development roadmap a crucial role is assigned to the evolution of the ALMA Science Archive to improve the user experience and maximize the scientific exploitation of ALMA data. To date, the Archive accounts for 10 cycles of data summing up to 1.4 PB of raw data and images representative of the data content that cover all the possible science categories from solar observations to cosmology. Most of the data are still unpublished: the ALMA Science Archive is a gold mine for archival users! The expected telescope upgrade will costitute a huge challenge in the archival data management. In view of the next decade telescope development, several upgrades have already been applied to improve the Archive features and offer easy access and experience to the miners. In this talk I will present some of the already available features and examples of their application to science cases. In particular, I will focus on the results of the Additional Representative Images for Legacy (ARI-L) project that has been a European Development project for ALMA Upgrade leaded by the Italian node of the EU ARC. It increased the legacy value of the ALMA Science Archive by bringing the reduction level of ALMA data from Cycles 2-4 close to that of data from more recent Cycles processed for imaging with the ALMA Pipeline. The project produced, assessed the quality of, and delivered to the ALMA Science Archive more than 300000 images for more than 88.5% of the observational datasets from Cycles 2 to 4 processable with the ALMA Pipeline that were missing pipeline-generated images. ARI-L products are certified for quality and can be downloaded from the ALMA Science Archive as ``external products''. The ARI-L project documentation and website are publicly available through the ALMA science portal (https://almascience.org/alma-data/aril).

17:50 - 18:15
I will summarise recent and ongoing research highlights from the ALPINE survey, an ALMA large program that observed dust continuum and [CII] emission in a statistical sample of normal star-forming galaxies at z=4–6, highlighting their significance to our understanding of early galaxy evolution. Combined with ancillary data at UV through near-IR wavelengths, ALPINE provides the currently largest multi-wavelength sample of post-reionization galaxies and has advanced our understanding of (i) the interstellar medium properties and star formation activity, (ii) the gas content, (iii) outflows and metal enrichment of the circumgalactic medium and (v) the kinematics and merger rates, in galaxies at z>4. ALPINE builds the basis for more detailed measurements with the current and next generations of big telescopes, and I will show an overview of a number of legacy programs that are already being carried out with ALMA and JWST.

18:15 Maris Assimo - Paleo-spectroscopy: retrieve and complement past data for radioastronomy searches
Maris Assimo - Paleo-spectroscopy: retrieve and complement past data for radioastronomy searches
18:15 - 18:35
A plethora of microwave and millimetre wave molecular spectroscopy data are available to the radioastronomy community. However, some of it was collected several decades ago and its modelling is sometimes obsolete. Moreover, instrumental advances allow complementing the data with new measurements that extend the investigated frequency ranges and improve the quality of the spectral predictions. Therefore, retrieving and complementing past information is necessary to look for not yet detected molecules in space. Some recent cases related to molecules containing atoms of the third period will be discussed, focusing on the challenges derived by the presence of internal motions (i.e. methyl internal rotation) and preliminary searches on Alma Archive.

Andrea Possenti - Neutron stars pulsating in the mm-band: Italian perspectives (Invited)
11:30 - 11:55
The pulsed radio emission from the neutron stars has usually a steep spectrum, thus making difficult their investigation in the mm band. However, the availability of new instrumentation is opening new perspectives in the field, hopefully allowing us to address some long standing and still unanswered questions in the field of the emission processes from a neutron star magnetosphere. In particular, the presentation will focus on the expectations arising from the installation of a suite of high frequency receivers at the Sardinia Radio Telescope.

The most massive galaxies were the first to shut off their star formation, turning into quiescent systems when the universe was still young. This quenching process is still poorly understood, and to make progress it is crucial to study the role played by cold gas. I will present two different ways in which this can be done. Using millimetric observations with NOEMA, we detected CO line emission from three massive quiescent galaxies at z~1, and measured low gas masses. This suggests that quenching consists in the removal of cold gas rather than in the suppression of star formation efficiency. I will also present new results based on James Webb Space Telescope observations, in which we detect neutral atomic gas in a high-redshift quiescent galaxy using rest-frame optical absorption lines. I will illustrate the implications of this detection for models of galaxy quenching.

MmVLBI has revolutionised our view of black holes and have provided some of the most striking, high resolution images obtained by mmVLBI, like the first images of a supermassive black hole obtained by the Event Horizon Telescope collaboration (EHTC). But beyond these two best studied targets, M87 and SgrA*, the EHTC has been exploring a variety of nearby AGN allowing to study different local environments and jet properties. In this talk I will present an overview of the AGN that are targeted with mmVLBI at 1.3mm and 3mm, highlighting some of the recent results that have been obtained. MmVLBI is a powerful tool not only for observations of the accreting material at tens of muas resolution, but will be critical - especially as more baselines become available around the globe - to study jet launching mechanisms and how these connect to the more extended jet material which is studied with cmVLBI at mas resolution.

14:00 - 14:20
A key issue in galaxy formation and evolution is to deepen our understanding of the complex (astro)physical processes that govern the properties of galaxies on different spatial and time scales. One powerful method for achieving this task is to model the spectral energy distribution (SED) observed from galaxies at different stages of their evolution along cosmic history. To this purpose, we have developed GalaPy, a new library for modelling and fitting galactic SEDs from the X-ray to the radio band, as well as the evolution of their components and dust attenuation/reradiation. On the physical side, GalaPy incorporates both empirical and physically-motivated star formation histories, state-of-the-art single stellar population synthesis libraries, a two-component dust model for extinction, an age-dependent energy conservation algorithm to compute dust reradiation, and additional sources of stellar continuum such as synchrotron, nebular/free-free and X-ray emission from low and high mass binary stars. On the computational side, GalaPy implements a hybrid approach that combines the high performance of C++ with the user-friendly flexibility of Python, and exploits an object-oriented design via new-generation programming techniques. GalaPy is the fastest SED generation tool of its kind, with a peak performance of almost 1000 SEDs per second. It exploits fully Bayesian parameter space sampling, which allows for the inference of parameter posteriors and thus facilitates the study of the correlations between the free parameters and the other physical quantities that can be derived from modelling. The API and functions of GalaPy are under continuous development, with planned extensions in the near future. In this talk, I will introduce the project and showcase the photometric SED fitting tools that are already available to users, with particular focus on the performance on local and high-z dusty star-forming galaxies featuring prominent emission in the mm band.
