PF+Logbook+Week+of+November+26

November 26, 2007 Today I opened a few of the "good" files in graphical analysis and attempted to identify the emission lines. I figured out the ratio for the two biggest emisson lines. Then, I calculated the redshift by dividing the observed wavelength of the emission line by the rest wavelength of that same element and then subtracting 1. I did this for 2 elements: CIII] and MgII. I then averaged the 2 values for z to figure out the redshift of the two.

November 27, 2007 Today I continued going through the "good" files. I went through the file bq0004p0051. I figured out the ratio and identified the elements as [OIII] and Ha. I then divided the observed wavelength by the rest wavelength that I found in a table in "Nature's Most Powerful Monsters" and subtracted 1 to find the redshift. I then recorded it onto the little note pad on the bottom of the page.

November 28, 2007 Today, I worked on two more "good" files: bq0043m0925 and bq0038p0010.01. I figured out that they both had emission lines for Hb and [OIII]. and then I figured out the redshift for both after referring to the table in NMPM.

November 29, 2007 Today, Dr. Loughran gave KH and I a talk about the goals of our project and what we should each be working on learning to do (or in KH's case, refreshing himself on the subject). The objectives he gave us included: 1) learning to ID emission lines using ratios 2) learning to calculate z (redshift) 3) learning to type spectra (identifying which type of AGN a graph shows) And then in my case, I should be able to type, redshift, and analyze the chemical components of 10 AGN spectra from the "good" folder.
