Message from the International Astronomical Union #IAU:

IAU Hands-On Workshops - Call for Proposals for Workshops in 2026

The IAU calls for applications to organize workshops under the IAU Hands-On Workshops (I-HOW) initiative. These workshops aim at training early-career scientists from developing countries in accessing, reducing, and analysing the vast amount of data available in astronomical archives across the world, and using them for their research projects. Proposals to organise one of these workshops shall be submitted using the application form provided on the website by email to one of the members of the I-HOW Steering Committee.

The deadline for applications is December 31, 2025.

More information on the characteristics of the initiative, the procedure and selection criteria for workshops, and a link to the application form are available at: https://www.iau.org/Iau/Iau/Science/Trainings---Workshops/I-HOW-Hands-On-Workshops.aspx

Random #Debian Astro package of the week is skyview. SkyView is a "virtual" observatory dynamically generating images of the sky in different wavelength regimes from a static image database. SkyView is intended as a quick look facility to see the heavens.

This package includes the executable.

Random #Debian Astro package of the week is jython-stilts. The STIL Tool Set is a set of command-line tools based on STIL, the Starlink Tables Infrastructure Library. It deals with the processing of tabular data; the package has been designed for, but is not restricted to, astronomical tables such as object catalogues. Some of the tools are generic and can work with multiple formats (including FITS, VOTable, CDF, CSV, SQL and

#AstroPython #VirtualObservatory #AstronomySoftware #ScienceSoftware

Random #Debian Astro package of the week is python3-pymoc. PyMOC provides a Python compatible library for handling MOCs.

Frequently astronomical survey catalogues or images are sparse and cover only a small part of the sky. In a Multi-Order Coverage map the extent of data in a particular dataset is cached as a pre-calculated mask image. The hierarchical nature enables fast boolean operations in image space,

Random #Debian Astro package of the week is topcat. TOPCAT is an interactive graphical viewer and editor for tabular data. Its aim is to provide most of the facilities that astronomers need for analysis and manipulation of source catalogues and other tables, though it can be used for non-astronomical data as well. It understands a number of different astronomically important formats (including FITS and VOTable) and

Random #Debian Astro package of the week is libjsamp-java. The Simple Application Messaging Protocol (SAMP) is a messaging protocol that enables astronomy software to interoperate and communicate as part of the Virtual Observatory (VO). JSAMP provides a hub implementation for SAMP, suitable for standalone or embedded use.

JSAMP also offers a set of classes which can be used to implement SAMP

Random #Debian Astro package of the week is python3-pyvo. The pyvo module currently provides these main capabilities: Find archives that provide particular data of a particular type and/or relates to a particular topic search an archive for datasets of a particular type. Do simple searches on catalogs or databases get information about an object via its name.

This is the Python 3 version of the package.

Random #Debian Astro package of the week is aladin. Aladin is an interactive software sky atlas allowing the user to visualise digitised astronomical images, to superimpose entries from astronomical catalogues or databases, and to interactively access related data and information from the Simbad database, the VizieR service and other archives for all known sources in the field.

Random #Debian Astro package of the week is python3-gavo. The Data Center Helper Suite (DaCHS) is a collection of Python modules (with some exceptions) to help you in setting up and running a VO-compliant data center. Moreover, some parts of this code are useful for client-side applications.

In addition to starting a SAMP Hub, the 'jsamp' tool allows for monitoring, snooping, testing, and stress running hub instances, or setting up a bridge proxy between two or SAMP hub instances.

* Manipulate: the generated object can be manipulated so than modifying the
original query.
* Translate: an interface and some implementations lets translating SQL
into other languages like SQL.

I’m also interested in #fediverse #interoperability across instances not running #mastodon… after all, my thesis was on the interoperability afforded by the #VirtualObservatory #IVOA protocols across #archives and software tools. https://fedi.simonwillison.net/@simon/109299934441703765

@vicgrinberg I used to be very active in the #VirtualObservatory and #IVOA before I switched gears into Systems Engineering… my thesis was about that! http://hdl.handle.net/10481/2323

@vicgrinberg say hi! to Pedro Osuna, Deborah Baines, Christophe Arviset, and everyone having to do with archives and #VirtualObservatory… they are quite friendly!
