Miles Garcia Research Journal (Summer '21)

6/7:

  • Met with Reshmi, Massimo, and Brian to discuss research goals for the summer
  • Began installation and setup of VEGAS from Daniela's tutorial
  • Created Twiki account
  • From Group meeting: Continued to finalize research goals. Access to VERITAS GRB spreadsheet.
6/8:
  • Continued to try and set up VEGAS.
  • Met with Daniela about VEGAS setup issues, refered these issues to Deivid over Slack also.
  • Began looking at GCN's and VERITAS GRB Spreadsheet
6/9:
  • Got access to VERITAS data from UCLA for VEGAS setup.
  • Continued setting up VEGAS (Stages 1-5 look good now)
  • Continued to cross-reference VERITAS-observed GRB's with GCN's
  • Looked through 2020 VERITAS/VHE Observations & pSCT Presentation slides (Summer 2020 Colloquium Series)
6/10:
  • Ran VEGAS Stage 6 with Crab Data, worked properly this time (multiple runs included)
  • Continued to cross-reference VERITAS-observed GRB's with GCN's (went through all 2021 GRBs not on the spreadsheet)
  • Attended Reshmi's talk for Barnard Lecture Series
  • Looked through plots generated by VEGAS stage 6 for Crab Data
6/11: 6/12:
  • Finished REU Intro Presentation
  • Finished slides for Monday group meeting
6/14:
  • Started looking at Peter Cogan's thesis to look at VEGAS Analysis stuff
  • REU Lunch-- presented my project information, background on GRBs
  • Group Meeting-- presented info on VERITAS GRB Observations, next steps (choosing what GRBs to analyze), and readings I did on GRBs. Came up with some steps for deciding what other GRBs to do analysis on.
6/15:
  • Looked at spreadsheet of VERITAS GRB Observations to get an idea of what information is missing (and can be filled in)-- specifically for Swift GRBs
  • REU Lecture on Dark Matter
  • Met with Reshmi about accessing VERITAS data (elogs, loggen), steps to get started with choosing GRBs
  • Read parts of article Colin sent about short GRBs from BNS
  • Started looking at Tevcat & VERITAS data
6/16:
  • Gathered information from Tevcat and GCN's on the 4 VHE GRBs listed on Tevcat. Plotted the GRBs on a map of the galactic plane.
  • Began running VEGAS analysis of the most recent GRB detection from last Friday (GRB210610B). Runlist, time cuts and extra options provided by Deivid in order to have an accurate cross-check. Using VEGAS v2.5.7 because Deivid reported potential issues in v2.5.8.
  • Read Taylor Aune's slides on GRBs from 2010 talk.
6/17:
  • Updated Tevcat GRB spreadsheet with information about time after initial observation in which VHE rays were still observed (how long after a GRB is observed can we still see VHE?)
  • Worked with astropy to create the same mapping of GRBs as the automatic plot from Tevcat
  • Still waiting on VEGAS (or maybe it has failed?)
6/18:
  • Updated Tevcat GRB spreadsheet with information about time after initial observation in which VHE rays were still observed (how long after a GRB is observed can we still see VHE?)
  • Worked with astropy to create the same mapping of GRBs as the automatic plot from Tevcat
  • Still waiting on VEGAS (or maybe it has failed?)
6/21:
  • Added GRB210610B (and additional information about it) to the list of GRBs observed by VERITAS
  • Attended both sessions of the VERITAS Summer Collaboration Meeting
  • Meeting with Reshmi about plans for this week
  • Started looking at general ideas for motivation-- why study GRBs? Good starting point-- slides for REU Introduction Presentation
6/22:
  • Attended Morning Session for VERITAS Summer Collaboration Meeting
  • Went to Barnard Summer Colloquium Series & REU Lecture Series
  • Continued working on motivation for GRB analysis-- went back through Reshmi's slides from the first Barnard Lecture Series meeting to add to motivations
6/23:
  • Attended both sessions of the VERITAS Summer Collaboration Meeting
  • Continued adding points for motivation stuff
6/24:
  • Attended morning session of VERITAS Summer Collaboration Meeting
  • Went to Barnard Summer Colloquium Series
  • Meeting with Reshmi & Undergraduates-- basics of VHE Gamma Ray Astronomy, VERITAS, CTA
  • Met with Deivid about plans for future, GRB analysis, etc
6/25:
  • Started working on slides for group meeting Monday-- Tevcat info, Motivation stuff
  • Looked into python stuff for reading in csv files (potentially for editing GRB Observation spreadsheet with some gammapy utility)
6/28:
  • Finished slides for group meeting
  • Looked into gammapy EBL absorption models
  • Group meeting: Discussed plan for GRBs to analyze. Do weighting function for Tevcat GRBs, then get zenith information to find Energy threshold on Deivid's list of GRBs --> compute updated weight for those with accurate energy threshold.
6/29:
  • Started looking for Energy Thresholds for the Tevcat GRBs-- some are difficult to find
  • Got zenith angles for VERITAS GRBs, used VERITAS performance papers to calculate energy threshold based on zenith angles.
  • Got gammapy working thru nevis cluster
