Looking at X-ray sources
Objects sometimes have more than 1 x-ray source.
Now look to see which sources are closest to the centers of the globular clusters.

To: [email protected]: [email protected]: X-ray source information
Dear Dr. Morris,
Here are the 10 x-ray sources that we would like more information on:
NGC 6541 Source 1NGC 6717 Sources 1-2Lynga 7 Sources 1-4NGC 6749 Source 1Ton 2 Source 1NGC 6723 Source 1
We need the additional information ASAP because we only have 20 minutes of class left.
Thank you!Mrs. Tykoski’s 7th Period Class
![Page 28: X-Ray Vision](https://reader036.vdocuments.mx/reader036/viewer/2022062410/56815ea5550346895dcd32f2/html5/thumbnails/28.jpg)
Hi there! The next thing you want to look for is the number of photons (energy packets) in the 3 groups. X-ray astronomers divide these photons into 3 groups: high energy photons, medium energy photons, and low energy photons. The best x-ray sources will have similar numbers of photons in all 3 of these bands.
I’m attaching this information for 9 of the 10 sources you requested. We had a telescope malfunction when looking at NGC 6723. You need to narrow down your list to 3 X-ray sources for me to send on to Chandra. I will need your recommendation by today.
Cheers,Dr. David Morris

Criteria #2
Look for sources that have similar numbers in the low, medium, and high energy bands in the X-ray

Dear Dr. Morris,
Here are the 3 x-ray sources that we recommend for Chandra:
Lygna 7 Source 4Lygna 7 Soruce 3NGC 6717 Source 1
We hope we made good picks!
![Page 59: X-Ray Vision](https://reader036.vdocuments.mx/reader036/viewer/2022062410/56815ea5550346895dcd32f2/html5/thumbnails/59.jpg)
Wow! I’m really impressed with how much data reduction you did in such a short period of time! Thank you for helping me out with this. I’ll send the recommendations to Chandra!
