An Afternoon of Plotting…

Filed under: Astronomy, School — Tags: , , , , — George Privon @ 15:35

… models.

I’ve been working quite a bit lately on my thesis. Fleshing out chapters and adding figures. One part of this is discussing the models of starbursts and active galactic nuclei that I’m using to study Cygnus A. So, I’ve made a couple plots showing the effect changing the parameters has on the models.

This plot shows the energy re-radiated by a clumpy torus in an active galaxy. The various panels show how the emission changes with the variety of parameters. More information on the model is available at https://newton.pa.uky.edu/~clumpyweb/. I’ll also have a bit of a writeup in my thesis eventually…

Memorial Day Ride

Filed under: Cycling, Virginia — Tags: , , — George Privon @ 16:30

One of the great things about Charlottesville is the outdoors activities which are easily accessible. This includes mountain biking, and suitable trails are scattered around town. My favorite place is Walnut Creek Park, which is just south of town off Old Lynchburg Rd. Fortunately, it is only ~10 miles away from my house…

So, this morning I headed out around 7:45 to hit the trails. After the 10 mile “warm-up” ride to get to Walnut Creek, I started by bombing down one of my favorite trails which features some nice technical turns as well as a stream crossing. Nearly two hours and 14 miles later, I emerged from the woods, almost totally wiped out. There are some great trails down there, most built by the Charlottesville Area Mountain Bike Club I believe. Lots of good climbs and rocky patches keep things interesting.

Almost 4 hours after I left, I returned home, only dragging a bit though. 35 miles under my belt and a great start to the week.

The Crack Post

Filed under: Climbing, West Virginia — Tags: , , , — George Privon @ 20:46

I had my first introduction to 5.9 handcracks yesterday at the New River Gorge. It was fantastic. I fell a lot. But eventually scratched my way up after hangdoging. I managed to escape with only a few scabs on my hands and wrists from the hand jams, but it was great.

I met up with Mike and friends at the New River Gorge for a day of climbing (he’s still there climbing). We spent most of Saturday at Junkyard, climbing a mix of moderate routes (on toprope for the most part). There were a couple classic routes, ranging from 5.6 to 5.10b. And, the best part.. there were very few people, even though it was Memorial Day weekend!

After spending most of the day at Junkyard, we headed over towards “Endless Wall” for some sport climbing. It was a bit more crowded, but we managed to find some short sport climbs to do. We started getting hungry around 430 and opted to beat the rush and head to Pies and Pints for pizza, before it got busy.

Through the Roof

Mike and I split the “Cuban Pork Pie” which included pulled pork, pineapple, carmelized onions, feta cheese and jalapenos. It was delicious. And, we had a pitcher of the local brew to wash it down. So, no complaints.

Not finished yet, upon returning to our campsite, we hiked a bit further down the road to run some laps on a 5.10b just down the hill. We wrapped things up as the sun set behind the rim of the gorge.

I had a great day getting back on rock. I’m hoping for more this summer… I’ve uploaded a bunch of pictures from the day to my flickr page:

Here’s a cool shot I got while at last week’s “Fridays After Five” in Charlottesville. I saw some kids running around playing and happened to snap the shot just as they both tumbled to the ground.

Productive Few Days

Filed under: Astronomy — Tags: , , , , — George Privon @ 17:33

Well, it’s been a good past few days on the research front. I had my first meeting with my advisor in over a month and got a telescope proposal worked out for the ARC 3.5m in Sunspot, MN to get some data on high redshift quasars. I suspect we’ll hear back on the proposal in a week or two.

In addition, I’ve been working on my reduction of some [[wikpedia:Hubble Space Telescope]] data for our study of the jet-gas interaction in a seyfert galaxy. I just finished reducing the data for the final filter. Next, I’ll begin processing the images to isolate the contribution from just the emission lines (so I’ll be removing the continuum light from the stars in the galaxy). This will allow us to study the properties of the AGN by comparing the morphology and energy output in various emission lines.

Finally, I’ve obtained some data from TripleSpec of another Seyefert galaxy for a separate project. I’ve started playing around with the tool to extract the data, and have made some progress with that. Hopefully in the near future, I’ll have a nice spectra I can show off of the galaxy. I’ll try and post a nice example if one comes up.

My Saturday Office

Filed under: Astronomy, Photography, Virginia — Tags: , — George Privon @ 08:16

I spent yesterday morning at the Charlottesville City Market and the Downtown mall, shooting some black and white film with one of my 35mm cameras. I developed the roll when I got home and they turned out quite nicely. I plan to scan them in soon and will then edit/upload them. There was a wide variety of people out and about in both places.

After finishing scanning the pictures, I continued working on my thesis on Cygnus A. I’m in the writing phase, and it looks to be a fairly involved process. I spent several hours on it last night, adding material to the chapter on the Spitzer Space Telescope. Fortunately the job was made easier by being in my “Saturday Office” (my front porch) with a glass of lemonade and beautiful sunny weather.

Moon & Clouds

The window on the top floor of my house looks towards the rec house for my subdivision. There’s some security lights which backlight a few trees. It always looks cool, and I’ve been meaning to take a picture of it for a long time. Well, last night the Moon and some light clouds were overhead as well, so I finally took the shot!

San Francisco Weekend Trip

Filed under: California, Photography, Travel — Tags: , , — George Privon @ 11:45

I just returned from a weekend in SF visiting Lydia before she heads off to Alaska. We had a fun few days wandering around SF, hiking and flying kites. As usual, I took a bunch of pictures. The digital ones taken are already edited and online at the link below. I also took some shots with my Mamiya 645, and I’m still waiting to get those developed and scanned in.

Thunder Mountain Line

Thunder Mountain Line

Originally uploaded by GeorgePrivon

Several years ago, my family went for a ride on the Thunder Mountain Line in Horseshoe Bend, Idaho. It’s a scenic train ride between Horseshoe Bend and Cascade. We did the “Wild West Train Ride” as a Mother’s Day present. I shot about a roll of B&W film on the ride and have just now started scanning it in..

One of my summer projects is to scan in the large amount of developed film and slides I have.. so there will be more appearing on my flickr page in the coming months.
