Administrative Week

Filed under: School — Tags: — George Privon @ 17:53

This last week has been slow in the research department. I got some things done both for classes and TA work though. Most of it consisted of tracking down people to check on things (where’d that CCD camera we ordered go? etc). I’m happy to say that most of it got resolved relatively easily.

This weekend is also the visiting weekend for prospective students. Seven of the accepted students are here to tour the department, find out what we’re working on, and meet the graduate students. I’ve been to a couple meals with them and taken them to/from some of the visits (NRAO Technology Center, Fan Mountain Observatory, etc). It has been fun getting to meet them all. I’m looking forward to hopefully seeing them in the Fall! Things are wrapping up tonight with a party, which is always a good time.

On the personal front, as soon as this post is done I will be editing my pictures from observing in Green Bank, then hopefully the pictures from New Orleans. Links will be posted when those are done…

“Nawlins”

I spent this past weekend in New Orleans with my NASA friends who were attending the National Science Teacher Association (NSTA) Conference. I attended a bit of the conference and did some sightseeing as well.

On Saturday, after a local styled omlette for breakfast, Aleya and I wandered around the waterfront near the financial district. Right off the bat we saw part of a breakdance performance on the street. Quite impressive!

After that we continued down the waterfront before heading into the conference center to attend a seminar and walk around the exhibit hall. While the seminar on professional development left something to be desired, there was lots of cool stuff at the exhibit hall. We dissected an owl pellet, constructed a model cell, and did an electro-chemistry demo. Aleya topped it all off with a raffle win (her 2nd of 3 for the conference), walking away with a dinosaur tracking kit, model kidney, and a beaker of shiny rocks. I won the dubious honor of helping carry the loot :p

Naturally we had seafood for dinner before watching a couple hours of Feynman videos. They were quite interesting.. He has a unique take on things and an excellent ability to provide explanations for things in relatively simple terms. Aleya capped off her wining streak at this event by winning a Feynman movie and book as a door prize.

Sunday morning was Aleya’s session on “Kinetic Astronomy” at the NSTA conference. It went quite well and seemed well attended. After wrapping up the conference events for the weekend, we took the streetcar out to Audubon Park. It was a gorgeous day and there were lots of people out walking, biking, and just laying in the sun. We walked most of the way back to the downtown area, passing through the park and the Garden District. Only stopping to eat some strawberries, a snowball (sno cone) and a hot dog (well, and so Aleya could accidentally sit on an ant colony! Oops!).

Upon our return, we met up with Laszlo and Emilie at the Cafe Du Monde for some coffee and beignets. The rest of the afternoon was spent wandering around town. We stopped in for a drink on Bourbon Street before heading to a restaurant for a late dinner, with a stop by Preservation Hall.

Shortly after dinner, we were joined by an old friend of mine from Idaho who is living in New Orleans. He’s both a musician and a yoga teacher, so we got a bit of local info. Sadly our time was limited due to an early flight out on Monday morning, but we managed to walk down Frenchman Street and poke our heads in a bar to hear some “trad” jazz, which was quite cool.

All in all, a short trip, but packed with as much fun as could be managed. I’d certainly like to visit again, see more of the city, and listen to more music!

“We’re jazzed you’re here”

Filed under: Louisiana — Tags: , — George Privon @ 00:38

Landed in New Orleans a few hours ago and was greeted with the above slogan. As typical for me, the flights were delayed, although perhaps I can just blame that on flying through Atlanta?

After getting back from observing around 8am, I slept until around noon. The afternoon was spent packing and taking care of little errands before flying. I’m in New Orleans for the weekend with some friends. They are at the National Science Teacher Association 2009 Conference. I’ll be joining them for a couple of the seminars, and hopefully some sightseeing later on.

Having never been to New Orleans, I am looking forward to doing a bit of exploring! Naturally, I’ve brought my camera and should have some good pictures to show for it.

10 Hours into the Observing Run

The observing run has been going quite smoothly so far. I haven’t had any trouble with the telescope or any other equipment. RFI seems to have been minimal as well. I’ve split the 10 hours I’ve used so far between two galaxies; 3 hours on one, and 7 on the other. I’m planning to spend the rest of the night on the latter galaxy, giving it about 9 hours total. This, plus some calibrations should wrap up the night nicely.

Quick looks at the data are promising. Our observing program was intended to look at two Seyfert galaxies which have upper limits on the neutral hydrogen (HI) mass. Using the improved sensitivity of the Green Bank Telescope, we were hoping to detect emission from the HI and possibly use the information to fir another piece of the puzzle for the two galaxies. As I said, things are looking promising, I think we might have detected the HI in both galaxies along with some other potentially interesting features. A proper reduction will be necessary to make be certain however.

Observing here in Green Bank has been a great experience. I’ve enjoyed meeting the staff here and enjoyed using the telescope. I hope I can come back, although the option to observe remotely exists.

At any rate, my observations are automated for the next 2 hours, so I think I’m going to catch a quick nap…

Orion and the GBT




Orion and the GBT

Originally uploaded by GeorgePrivon

I took this somewhat unique picture on Tuesday night while in Green Bank, WV observing on the Green Bank Telescope (GBT). The telescope is nicely lit up for the shot, which is unusual. In this case, there were some issues with the HVAC system and the lights were turned on so it could be repaired. Naturally, this put a temporary end to our observations, but we made the best of it and took some pictures. This is probably the best of the ones I took. I have a few more which I’ll upload later.

The net result of the night was ~5.5 hours of the 11.5 hour run lost to equipment issues. We managed to make good use of the 6 hours we did have, but we still need more data.

Fortunately, due to a combination of weather and our lost time, we were given more time tonight to finish our observations! As I write this, I am back in the GBT control room in Green Bank. My observing scripts are ready to go and I’ll begin observing in a little over an hour. As before, I’ll be providing updates on twitter as I go.

With an hour left to go, the GBT is currently being used as part of a global network of radio telescopes to look at Cygnus A, a radio source which is near and dear to my heart (I’m finishing my MS thesis on it). Hopefully they get some good results!
