sYSOm generates emission maps of young stellar objects (YSOs) based on a model composed of a central star, modeled as a blackbody, and a dusty circumstellar disk. The disk is assumed to be geometrically flat with radial-dependent temperature and surface density prescribed by power laws.
The local intensity of the disk, seen at a given inclination, is then given by a blackbody emission at the local temperature weighted by an factor that depends on the local surface density and a chosen (…)

Maintenance / service outage
You can find some information in advance for planned maintenance or have a list of past outage. We are sorry for the inconvenience of any failure. Please contact the jmmc-user-support for any issue.
6th of may 2025 A third outage occured in the morning on most JMMC services hosted at Grenoble due to network instability. Sysadmin still are working to solve it.
24-25th and 28-29th of april 2025 Some JMMC services hosted on the OSUG’s cloud infrastructure get lot network cuts. Some (…)

At the last SPIE meeting during the conference "Optical and Infrared Interferometry and Imaging VIII" prizes have been awarded to people deeply and succesfully involved on the development and the exploitation of interferometric instruments. Because the conference was held online two years ago during the pandemic, the ceremony included the 2020 awards.
The recipients were:
Guy Perrin, Fizeau Prize 2020 and Frank Eisenhauer, Michelson Investigator Prize 2020, both for, among other things, (…)

Please do not hesitate to report any feedback, precious as you know for the improvement of this tool that allows a user-friendly use of some imaging algorithms for interferometry.
OImaging has been presented at different international meetings, the latest one in Montreal for the SPIE conference this week (see the previous news). The first presentation, at Exeter in April, resulted in a video clickable on OImaging webpage.
