The HEASARC Users Group and the LAMBDA Advisory Group

The HEASARC Users Group (HUG) has as its prime directive to "evaluate and monitor the performance of the HEASARC."

Other terms of reference and organization are as follows:

  • Solicit input on the operation of the HEASARC from the astronomical community.
  • Recommend guidelines for community access to the HEASARC.
  • Provide help and information to the HEASARC on a wide range of disciplines relevant to its activities.
  • Encourage interaction and coordination with other mission facilities and data archives, both within and outside NASA.
  • Review an annual report on the HEASARC activities and progress.

The HUG provides feedback to the HEASARC Director, as well as to NASA Headquarters.

The current members of the HUG are

      * Greg Madejski, Chair, (SLAC)
      * Matteo Bachetti (INAF)
      * Tesla Jeltema (UC Santa Cruz)
      * Jan-Uwe Ness (ESA)
      * Paul Ray (NRL)
      * Colleen Wilson-Hodge (NASA/MSFC)

The HEASARC Users Group provided valuable feedback on the HEASARC's progress and future plans in April 2022 (prior to the HEASARC's PPBE presentation to NASA HQ) and on the HEASARC Programmatic Review Proposal content in January 2020, prior to proposal submission. Informal feedback on specific technical topics (e.g. the HEASoftpy Python wrappers, and the heasarc@sciserver science platform activity, etc) has also been solicited and recently provided by HUG members. Formal written reports on earlier meetings in February 2018 and November 2016 can be found here and here.

Within the HEASARC, LAMBDA has its own separate Advisory Group focusing on issues of primary relevance to the cosmic microwave backround (CMB) community.

The current (outgoing) members of the LAMBDA Advisory Group (LAG) are

      * Renee Hlozek, Chair (Dunlap Institute, U. Toronto))
      * Ted Bunn (U. Richmond)
      * David Chuss (Villanova U.)
      * Tom Crawford (KICP, U. Chicago)
      * Gary Hinshaw (U British Columbia)
      * Jeffrey McMahon (U. Michigan)

A new LAG is currently being formed and interested members of the community should contact Dr. Tom Essinger-Hileman (thomas.m.essinger-hileman 'at'

The most recent meeting of the LAMBDA Advisory Group was on Friday, March 23rd, 2018. The report from this meeting is available here. Before that, the previous LAG meeting was on Monday, November 28th, 2016, and the report from the 2016 meeting is posted here.
