The Observatorio Astrof\u00edsico de Javalambre (OAJ)<\/a> is a Spanish ICTS that hosts the JST250 and JAST80 telescopes, with very large fields of view and panoramic instrumentation, JPCam and T80Cam, in which the surveys J-PAS and J-PLUS are carried out.<\/p>\n

J-PAS<\/a> is a narrow-band and very wide field cosmological survey, will observe more than 8000deg2<\/sup> of the northern sky and will measure photometric redshifts with a precision of ~0.003(1+z) for a large number of luminous red galaxies, star forming galaxies, and QSOs.This will be possible thanks to the combination of a large FoV camera and the unique photometric system, consisting of 54 narrow band (NB) filters and 2 broader filters covering the full optical range. This is equivalent to low-resolution spectroscopy (R~60), for each pixel across an area similar to that covered by SDSS. Furthermore, the spatial sampling of the camera and the large field of view allows us to get spatially-resolved spectral energy distributions in the optical range for nearby galaxies (z < 0.1) and integrated photometry for galaxies up to z ~ 1. J-PAS will thus provide an excellent database for galaxy evolution studies, from the local to the more distant Universe.<\/p>\n

J-PLUS<\/a> is observing 8000deg2<\/sup> of the northern sky with 12 filters that include the SDSS filters plus intermediate and narrow band filters placed at the location of the most relevant emission lines (e.g Ha, [OII] 3727), and the absorption features at z = 0 (CaHK, Hd, Gband, Mgb, CaT). Furthermore, this system allows us to trace well the D4000 break which is a good indicator of the ages of the stellar population. The telescope has a camera of 1.4 x 1.4 deg2 and can offer a 3D view of the local Universe with a spatial scale of 0.55 arcsec\/pixel. So far, J-PLUS has observed more than 4000 deg2<\/sup>. The first ~3000 deg2<\/sup> are publicly available at the J-PLUS website, amounting to more than 47 million galaxies and stars with full photometric information.<\/p>\n

The spatially-resolved stellar population properties (e.g. star formation rate) and distribution of the ionized gas from J-PAS and J-PLUS (or equivalent observations with their photometric systems) can be combined with spatially-resolved neutral gas in galaxies to further investigate the origin of the Hubble sequence and the role of AGN, star formation and environment in galaxy evolution.<\/p>\n

The SKA Observatory<\/a> interferometers will be the most sensitive radio telescopes on Earth. The unprecedented sensitivity of these instruments will help to address a wide variety of fundamental questions covering astrophysics, fundamental physics and astrobiology. Their sensitivities, angular resolutions, and fields of view supersede, by at least one order of magnitude, the performances of all current radio astronomical facilities. Meanwhile, an entire family of precursor and pathfinder facilities are already in place and carrying out scientific studies related to future SKAO activities.<\/p>\n

Despite being located in the southern hemisphere, SKAO’s telescopes will be able to cover a significant portion of the J-PAS footprint. For the portion of the sky covered by both facilities, cross-identified sources will benefit from a rich set of data covering a wide range in wavelength\/energy. Combining data from J-PAS and the SKAO surveys, galaxies that will be fully characterised with the photometric data of J-PAS (accurate redshift, spectral energy distributions and properties of their large-scale environment) will also get their neutral gas content and dynamics measured by SKAO’s interferometers.<\/p>\n

Scientific objectives of the meeting<\/strong><\/p>\n

The scientific objectives of the meeting will be first to present an overview of SKAO’s telescopes capabilities, as well as of the current precursor and pathfinder facilities, with an emphasis on the Spanish involvement. With these tools in hand, the attendance will elaborate on the multiple possible synergies between J-PAS and SKAO<\/strong>. The meeting will be open to the entire community<\/strong> interested in the use of these facilities which will be available over the next decade – in the presence of the main actors on J-PAS and SKAO sides. This will be a unique opportunity for the community to develop concrete scientific cases, eventually leading to a proposal for a legacy project between OAJ and SKAO over the equatorial zone<\/strong>. These discussions will be held under the precepts of Open Science, at the centre of both organizations.<\/p>\n

We therefore welcome contributions from the entire community, from all fields, of current examples or concrete ideas of synergies between SKA and OAJ infrastructures, more particularly, between J-PAS\/J-PLUS and SKA pathfinders, in preparation for SKA and future OAJ surveys.<\/strong><\/p>\n

Registration Fee:<\/strong> This meeting is supported by the RIA through a grant of the Ministerio de Ciencia e Innovaci\u00f3n. The registration fee is waived.<\/p>\n

Venue:<\/strong> The meeting will take place in Teruel, with the possibility to attend it virtually. The preferred attending (in person\/virtual) can be selected in the registration form.<\/p>\n

The second day of the meeting (November 29) will take place in the meeting room of the GAL\u00c1CTICA Centre for Astronomy, Education and Outreach located in Arcos de las Salinas, Teruel (transport will be organized). We will have a private visit of the center and of the Observatorio Astrof\u00edsico de Javalambre (OAJ) site during the afternoon.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
