AGN Spectral Energy Distributions of GLAST Telescope Network Program Objects

The Gamma-Ray Large Area Space Telescope (GLAST) has a proposed observing list that includes AGNs and Polars bright enough to be observed optically by amateurs and students. This observing list is maintained by the "GLAST Telescope Network" (GTN) and includes a number of objects that have yet to be observed by the Spitzer Space Telescope. Our project will observe one of these objects with the Spitzer MIPS and the IRAC instruments to determine their Spectral Energy Distribution (SED), which will be compared to a computer model of disk emission in order to determine what component of the SED is due to the disk and what component is due to synchrotron radiation induced by the jets. In addition we will observe our program objects prior to, simultaneously with, and after Spitzer observes them. This gives a direct connection from Spitzer research to student activities in the classroom.

Status: MIPS and IRAC Observed and Archived

The project was approved by the Spitzer Science Center director. He selected one of our four potential AGNs as our primary target (GTN #7, 4C 29.45) and we edited the proposal to reflect this change. After this decision, Mark Lacy reworked the AORs to refine the time needed to gather the data.

This message from Mark summarizes the change in the AOR: ..... juggled the MIPS exposure times to make sure we get a detection at 160mu (the least sensitive wavelength). I've kept the total length of the AOR almost the same (in fact it's 10s shorter), but the MIPS AOR changed

old: 24mu 3s x 3 cycles
       70mu 3s x 5 cycles
     160mu 3s x 5 cycles

new: 24mu 3s x 1 cycles
      70mu 3s x 1 cycles
      160mu 10s x 3 cycles

IRAC was fine as is.

The proposal has been sent to the scheduling team but as of this writing they have not contacted us. The optimum observing window is in May, therefore we expect to hear from them sometime in April.
