Title:: Data Discovery Using the Virtual Observatory Registry
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: There are many ways to access registry data. A fairly powerful one is the Web Interface to the Relational Registry (WIRR for short) at http://dc.g-vo.org/WIRR To actually speak to the VO services discovered, clients speaking the service's protocols are still required. In this tutorial, Topcat plays that role. Starting from a simple use case, we work up to investigating the Tully-Fisher relation in different bands using independently discovered resources.

Title:: Discovery of Brown Dwarfs mining the 2MASS and SDSS databases
Date:: 27 Dec 2024 08:31:05
Publisher:: The GAVO DC team
Description:: Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. We propose here to mine the 2MASS-PSC and SDSS-DR9 databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red, an approach that perfectly fits into the Virtual Observatory.

Title:: Explore the Pleiades with TOPCAT and Aladin
Date:: 27 Dec 2024 08:31:12
Publisher:: The GAVO DC team
Description:: As stars in open star clusters are formed from the same matter at the same time and have only a small velocity dispersion, it is relatively easy to identify them from the background stars. In this tutorial, we will identify the members of the Pleiades kinematically and get an idea of our success by examining a color-magnitude diagram using TOPCAT, Aladin, and a few VO services.

Title:: Exploring Gaia data with TOPCAT and STILTS
Date:: 27 Dec 2024 08:31:00
Publisher:: The GAVO DC team
Description:: This tutorial uses data from Gaia DR2 to lead you through some of the capabilities of TOPCAT and STILTS. Use cases covered include a studies of the globular cluster M4 in proper motion space and the open cluster Hyades in the full phase space, matches between Gaia and HST data, and the creation of Hertzsprung-Russell diagrams.

Title:: GAVO Data Center Obscore Form
Short Name:: obscore web
Date:: 27 Dec 2024 08:31:13
Publisher:: The GAVO DC team
Description:: This is a form-based service allowing users to run simple queries against GAVO Data Center's ivoa.obscore table, with some nods to users looking of data near the optical waveband. For serious use, the `obscore table`_ should be queried through TAP. Note that queries without spatial constraints may take time out. You probably ought to switch to async TAP if you really want to run such queries. .. _obscore table: /tableinfo/ivoa.obscore?tapinfo=true

Title:: Identifying Brown Dwarf candidates in 2MASS and SDSS
Date:: 27 Dec 2024 08:31:02
Publisher:: The GAVO DC team
Description:: This tutorial is a comprehensive scientific usecase in which brown dwarf candidates in 2MASS and SDSS are identyfied. The surveys are queried using ADQL, and unncertainties in the data are solved with TOPCAT and Aladin.

Title:: Introduction to Simulation Databases - Density Fields and Dark Matter Halos
Date:: 27 Dec 2024 08:31:06
Publisher:: The GAVO DC team
Description:: This tutorial was created for a physics teacher workshop (~ high school level). It shows how to extract density fields and information on dark matter halos from the CosmoSim database using SQL queries. It is optimized for brevity.

Title:: Introduction to Simulation Databases Using CosmoSim
Date:: 27 Dec 2024 08:31:03
Publisher:: The GAVO DC team
Description:: This tutorial shows how to do first SQL-queries on cosmological databases, including retrieving mass functions, extracting merger trees or particles of a specific dark matter halo.

Publisher:: Centro de Estudios de Física del Cosmos de Aragón (CEFCA)
Description:: J-NEP PDR202107 Catalogue (July, 2024) is based on scientific images in 60 filters. J-NEP is a 60-band photometric optical survey based on images collected by the JST250 telescope and the Pathfinder instrument at the Observatorio Astrofísico de Javalambre (OAJ, Teruel, Spain) . Please include the following in any published material that makes use of this data: "Based on observations made with the JST250 telescope and PathFinder camera for J-NEP project at the Observatorio Astrofísico de Javalambre, in Teruel, owned, managed and operated by the Centro de Estudios de Física del Cosmos de Aragón."
