Research Journal (Summer 2020)

Monday, June 1

  • Various orientation meetings, discussed plans for the summer. Primary goal is to finish the SLSNe analyses and get more familiar with the theory.

  • Attended Ari's fermipy tutorial

  • started reading the X-ray SN2015bn paper

Tuesday, June 2

  • Tried to work on fermi analysis of SN2015bn, ran into error at the actual likelihood step "Attempt to set the value outside of existing bounds. Value nan is not between 1e-05 and 1000"

  • (was successful at preparing the preliminary files with all of the time cuts to remove contamination from the sun)

  • spent the rest of the day troubleshooting

    • I determined that I had updated Fermitools recently, so I tried undoing the update, but it didnít make a difference.

    • Tried using different model files, including one which had worked in an earlier analysis, but continued to get the same error

Wednesday, June 3

  • Continued to work on troubleshooting fermi analysis

  • Met with Deivid to discuss background theory of SLSNe and the magnetar model, as well as to work on troubleshooting the error

  • We came up with some ideas to work on, including looking through the xml file to make sure there are no obvious issues, trying to run the analysis for other time bins, and changing the model. Also discussed strategies for how to choose to fix/free sources in the model in general.

  • Group meeting

Thursday, June 4 - Friday, June 5
  • Continued working on troubleshooting fermi analysis, spoke more about it with Deivid via slack
  • I've determined that the issue is not specific to the particular model file I was using, or to 2015bn as a source (I tried different models, and did a test analysis with a different source, which also failed)
  • The next step will be trying to completely reinstall fermitools and see if that helps
Monday, June 8
  • Continued troubleshooting: tried reinstalling fermitools and anaconda, didn't help with the error. Trying to look online to see if anyone has had similar issues with fermitools, so far no luck.
  • Colin sent out a doodle poll for times for journal club
  • Group meeting - discussion of Wednesday's strike for social justice and the summer colloquium series (sign up on link)
  • Some fermi suggestions from group meeting: try running analysis with SN2015bn out of the model, make sure using the most up to date diffuse models, try using different optimizers.
  • Qi made a setup of fermitools on tehanu last year, if it is still up and I can't get my setup working maybe I can try using my files in that setup
  • Next Wednesday undergrads will give a short presentation on background material after reading papers
