Today was the final day of work!!! My presentation was much better than during the practice. I thought I did very well, but my brother said it was confusing. Then I stayed to watch the other presentations, they were all very good. Then all the astro interns were invited to a free lunch at Tully's. Great Day. I will miss the other interns.

practice presentations

Today, I fixed some parts of my presentation and did some more work just for getting it done. Then we did practice presentatoins, and I was second. I did well until the 10 minute-mark and then I got really nervous. Overall, it was about 15 minutes. It was pretty bad. But then I fixed it with Dr. Robinson and shortened it. I will practice at home, and make some notes so I will be prepared for Tomorrow.

Presentation deadline

today, I realized a mistake in the spreadsheet that I used. The broadline luminosity that I used for most of the scatter plots was copied from another spreadsheet, but I didn't notice that some of the objects were different, so they weren't the right values. So, I calculated the actual broadline luminosity and made new scatter plots. This turned out to give much better results with nice trends. Then I met with Dr. R to look over the plots and the ones I will use for the presentation. I made the final revisions on my powerpoint and handed it to Joe at 3:30. I had to look up what a MBH and ISIS stood for in case someone asked me that during the presentation.

PS: MBH is massive black hole, and ISIS is Intermediate dispersion Spectrograph and Imaging System.

Thursday and Friday will seem like light days (hopefully).

I hate IDL

today I worked on my presentation more. I got really stuck when I tried to plot a graph, and the fit to the graph on the same set of axis. for some reason IDL sucks and only plotted the spectrum graph. This got me frustrated for about 2 hours until Dr. Robinson sent me the graphs from IGOR PRO. By the end of the day I finished my powerpoint presentation with 18 slides. Then I went to meet with Dr. R to look over my slides. In the end, I was able to make some new scatter plots, but none which seem to have a good trend. Maybe tomorrow, I will be able to find some trends so that I can include that in my presentation.

Today I worked on my presentation and how I should present my data in the slides. I met with Dr. Robinson, who told me to organize the slides so that people would be able to understand. I sent him my presentation so far (9 slides) and he showed me how to organize them. We then had another meeting about what to calculate and make scatter plots of. Basically, we are looking for any possible trends. I will try to finish my presentation tomorrow, and send it to Dr. Robinson for some feedback. Then, if I have time I will work on the scatterplots he wanted me to make. I also tried to make an Fe X line after an oxygen subtraction for my presentation, but it was a pain on IDL, so I did it on excel.
Tomorrow seems like a busy day.

Undergrad research symposium

Today was the undergrad research symposium. Before I went to any of the presentations, I worked some more on my intern presentation. I made some changes to my presentation, and added a picture of a galaxy and an energy state diagram. I will need to e-mail Dr. Robinson about diagrams of some absroption lines, and for data.

The presentations I went to were Chris Mullarkey's, Becky Moore's, and Adam Podell. Chris Mullarkey was my undergrad who I was working with, and I understood all the different things he was talking about. Also, there was my name on the presentation, which I thought was cool.
Becky's presentation was about the coronnal mass ejections from the sun to the earth. This was cool to learn about. It was interesting to see.
Then, I finally saw this presentation on the effects of varying growth conditions on indium-arsenide quantum dots. This presentation was much more professional and advanced than I expected. This presentation was of interest to me, and he talked about growing InAs on a GaAs substrate, and because of different lattice constants, there was tension build-up, so the InAs formed dots on the GaAs, which allowed less tension in the crystal. The presentation was advanced, but really interesting.

well, in two days is the Undergrad symposium, which I think I am not going to present at, and next Friday is the intern presentations. Today, I was stuck trying to put data from excel onto a scatter plot that could be interpreted. So, I first had to make sure equivalent width values for the iron VII and iron X were not negative, which I finally got to work after using the H-alpha continuum height instead of the iron continuum height. Once, I got them all to be positive, I was only able to make one graph of iron VII EW v. BL luminosity. After we got back from our trip to the Eastman House, which was pretty cool to look at and tour, I finished making graphs of the
Fe VII/X EW v. BL luminosity, and Fe VII/X luminosity v. BL luminosity. The graphs do look somewhat good, although I'm not sure if we will be able to see any significant trends.
