We propose to work with members of James Bullock's group, including appropriate grad students and postdocs, on the first year paper on searches for dark matter annihilation in dwarfs with Fermi. They will provide us with the current best determinations of the dark matter density profiles in the dwarfs being considered (including new, unpublished stellar velocity data). These will allow us to interpret the Fermi data in terms of limits on the dark matter particle properties (mass versus annihilation cross section). They will also help in writing the appropriate sections of the paper.

Proposal submitted by: Tesla Jeltema, Johann Cohen-Tanugi, Eric Nuss

This is to keep archive of some checks of the distributions of some low- and high-level variables in bkg sets with overlays.

For the first comparisons I selected 2 bkg datasets, one without overlays (bkg-v15r39) and one with (v17r16). I selected some runs, to have little more that 200k events after the skim. The skim cut is simple, i.e.

ObfGamStatus>0 && TkrNumTracks>0 && CalEnergyRaw>5 && CalCsIRLn>4

First, let's plot some key variables after this first skim. From here on red means no overlays, black means overlays.

Take care, there's no selection here on CTBBestEnergyProb yet! We'll see later that this is not an issue.

In general in the overlayed set I find that more events with low energy pass the trigger and the filter. Low energy, low CalEnergyRaw and few tracks.
What happens to CTB vars due to these overlayed events? Ex: CTBCORE:

  • Top left: CTBCORE. Overlayed events have lots of events at low CTBCORE. This should be due to the events with low energy
  • Top right: McEnergy vs CTBCORE for overlays: note e.g. the corner at CTBCORE=0 and McLogEnergy=1
  • Bottom left: same for no-overlays: the events in the corner are missing, these are the events that show up in the CTBCORE distributions
  • Bottom right: CTBCORE distrib. for events with McLogEnergy>2.3 to cut low energy events

A more direct check: what is the difference for v17r16 events when overlays do not hit either cal or tkr? Compare newx plot on the right with bottom left in plot above.

Just to be sure: same plots with "CTBBestEnergyProb>0": no big change here.

 

Next, a look at the Psf CTB analysis to see what happens in detail to these events

This month, the diffuse group has been active preparing its contributions to ICRC. Several papers of LAT interest were reported at the conference by members of the diffuse group or other persons, namely:

  • on the LAT capability to measure local GeV to TeV electrons (Moiseev et al., arXiv:0706.0882)
    *an update of the diffuse models developed for LAT analyses (Porter et al., arXiv:0706.0221) including new gas rings and ISRF, anisotropic inverse Compton scattering, and the new cross-section for pi0 production from Tune Kamae's work.
  • the inclusion of nuclei interactions in the gas gamma-ray emissivity (Huang et al., arXiv:0706.0506) which results in spectral hardening at GeV energies. The cross-section is available at http://cherenkov.physics.iastate.edu/gamma-prod. The hardening is insufficient to explain the GeV excess. However, the possible instrumental origin of the EGRET GeV excess, as discussed by some EGRET team members, has appeared on arXiv:0705.4311 (Stecker, Hunter, and Kniffen). The emissivity hardening due to nuclei is important for the future interpretation of SNR GeV to TeV emission and for the diffuse models.
  • on the gamma-ray spectrum resulting from hadronic interactions in the interstellar gas surrounding SNRs (Moskalenko et al., arXiv:0705.3854)

What you have never dared ask about cosmic ray propagation has an answer in the annual review by Strong, Moskalenko, and Ptuskin that has appeared on http://arjournals.annualreviews.org/doi/abs/10.1146/annurev.nucl.57.090506.123011

At the ICRC, the HESS collaboration has reported a dozen new sources from their extended inner Galaxy. The fact that nearly all Galactic HESS sources appear to be extended (few arcminutes beyond the HESS 6' resolution) although they are not consistent with an extension of the diffuse GeV emission, is important for the future LAT diffuse modelling and source extraction.

Work is going on in the diffuse group on gas distribution for GALPROP and on the anisotropic IC emission due to the bright O and B stars distribution within 500 pc. The need for specific 'diffuse' tools is being evaluated.We had the addition of 5 new members to the group during June/July (Jean-Luc Starck, Omar Tibolla, Tom Dame, Markus Ackermann, and Guðlaugur Jóhannesson).

Mission News - April 2007

Mission News
Steve Ritz, Bob Naeye, and Julie McEnery

Recent activities have been highlighted by the rework and retest of spacecraft electronics and the completion of solar array development testing. A successful Pre-Environmental Review was held on April 11-12. The integrated spacecraft will soon undergo more than four months of environmental testing, starting with Electromagnetic Interference (EMI) testing, at General Dynamics Advanced Information Systems, in Gilbert, AZ.

Pictures of the observatory may be found here: http://glast.gsfc.nasa.gov/public/resources/images/

Due to complications of schedule with other planned launches from Cape Canaveral and other program considerations, the GLAST launch will occur no earlier than December 14. The mission team is considering the options and implications for a launch delay of up to a few months.

There was a Users Group telecon on 20 April. The next face-to-face meeting will be at Goddard on June 4-5.

The next Guest Investigator Workshop will be held in Los Angeles in May (http://gamma1.astro.ucla.edu/glast_2007/). Similar workshops were held near Washington, DC in January (http://glast.gsfc.nasa.gov/science/resources/workshop07/) and in Chicago in April (https://www.hep.anl.gov/glast_workshop/index.html). Additional workshops are being planned, including one in Cambridge, MA.

A workshop on VLBI in the GLAST Era was held on April 23-24 at Goddard.

The announcement for the first NASA-funded GLAST Guest Investigator (GI) Cycle has been amended. As you know, this program provides an opportunity for people at U.S. institutions to obtain financial support for GLAST studies. The GI program includes funding opportunities for (1) analysis of publicly released data, (2) correlated GLAST-related multi-wavelength observations, (3) GLAST-related theory, and (4) GLAST-related analysis methodology. The opportunity is open to LAT team members, but please note that the proposals can not be based at all on the access to the proprietary year-one LAT data. Proposals are now due September 7, with optional NOIs due on July 13. See http://glast.gsfc.nasa.gov/ssc/ for more details.

The MOU between GLAST and NRAO is complete and in signature cycle. The agreement provides up to 10% observing time on NRAO facilities (Greenbank, VLA, VLBA) to be awarded as part of the GLAST GI program. This is a great development for GLAST and NRAO science! Once the agreement is signed, we'll post it on the GSSC site and send out an announcement with details. There is also a press release being drafted. We're also exploring the possibility of a similar agreement with NOAO.

There will be a review of the GBM Instrument Operations Center on May 10 in Huntsville. Representatives from the LAT ISOC will attend.

Reminder: to sign up for the GLAST News, send an email to: majordomo@athena.gsfc.nasa.gov (leave the subject line blank). In the body of the message, please write the following: subscribe glastnews your-email-address

GLAST Public Affairs

GLAST public affairs telecons have restarted and now occur on a biweekly basis. Rob Gutro (GSFC) moderates these telecons, which focus on coordination of press-related activities. Participants include representatives from across the mission.

Rob Gutro is working on a Public Affairs Plan, which will describe public affairs and outreach efforts, written materials, press events, communications to NASA employees, creating and updating a website, and more.

Robert Naeye (SP Systems/GSFC) wrote a press release about the Pre-Environmental Review and environmental testing. It was issued on April 11. More press releases will be issued in the months ahead to inform the media about the mission and its schedule of milestone events.

Among various other activities to promote the mission, Rob Gutro and Robert Naeye are compiling a GLAST Science Writers Guide. The Guide is intended to be a handy source of basic GLAST information for journalists, and it is being based on successful Guides from other missions. A set of "Mission Messages" will be included in the Guide.

Work is continuing on animations of the spacecraft and other animations supporting anticipated science results.

At Julie Mcenery's suggestion the service challenge pages have been moved to the Data and Service Challenge space to reflect the expanded scope of the service challenge.
