Particles Behaving Badly - NPR
"That situation is playing out now, as outlined in a recent review paper in Nature. The conundrum in question is the decay of a particle called a B-meson, and how many electrons, muons, and tau particles pop out after a collision. Physicists in a handful of experiments around the world have all observed a preponderance of tau particles—not what current theories would predict."

Summer Summary
We had another great summer at JHU. Thanks to all who participated! Please take some time to look at the page listing all the talks and activities for the week, as well as the posters created by the summer students explaining their research projects.
If you do something interesting with your students related to your QuarkNet learning, or your cosmic ray detector, please let us know; we'd love to hear about the great science you're doing in your classroom.
Don't forget that there are several QuarkNet / JHU activities happening throughout the school year, beginning with International Cosmic Day (November), continuing with the LHC / CMS MasterClass and International Muon Week (late winter / early spring) and finally the JHU Physics Fair (April). And I can't leave out the Central MD Physics Olympics, hosted by our very own Tim Durkin at Liberty HS (late February). Hope to see you there!

Please click the titles to see a poster summarizing each student's research.
Posters can be downloaded (PDF format).
=====================================
Jack Carlton - Modeling Quantum Waves and Probability
Over the course of six weeks, I researched established wave function models. These models have already made large impacts on technology today. I used a couple of simulations in order to “look into” the quantum world. As a result, I am now able to comprehend the nature of particles and their waveforms.
------------------------------------------------------------------
Tatiana Davidson Bajandas - Modeling the Milky Way Rotation Curve with No Dark Matter
I constructed a model of the rotation of the galaxy using a simple bulge model. This model yields the curve expected without the gravitational effects of dark matter. Two mathematical models were used, one for the rotation of an object inside the bulge of the galaxy and one of an object outside of it. Distinctly lower rotational speeds for objects with large radii are observed, an attribute which conflicts with collected data, strongly supporting the existence of dark matter in the outer reaches of our Milky Way Galaxy.
------------------------------------------------------------------
Kyle Dickerson - Radio Astronomy with Pulsars
Pulsars are the rotating beams of electromagnetic radiation emitted from a neutron star. I have researched the proposal, discovery, function, and importance of pulsars using primary source documents. I have collected data from multiple pulsars and non pulsars by using the Greenbank-20 radio telescope through the Pulsar Search Collaboratory. Pulsars may be used to collect data concerning astrophysical phenomena.
------------------------------------------------------------------
Simon Liu - Modeling the Milky Way Rotation Curve
The purpose of this project was to construct a rotation velocity curve of the Milky Way Galaxy. Using Johns Hopkins University's Small Radio Telescope, I collected data on the radio frequencies of different parts of the galaxy and successfully recreated a rotation curve with a domain up to 8 kiloparsecs (kpc). By doing this, I hoped to find empirical evidence for unobservable matter in the galaxy. Because of the large deviation of the constructed rotation curve and the expected Newtonian rotation curve, I can conclude that there is indeed a large amount of matter that is undetectable by modern instruments.
------------------------------------------------------------------
Jason Zhao - Reconstructing Cosmic Ray Events With Muon Data
Isabelle Zhou - Characterizing Radio Galaxy Evolution Using the K-Z Relation
Using data from different sources and previous cosmological studies, I analyzed the relationships between redshift (z) and luminosity (K) in radio galaxies. After comparing my results to those of previous papers, I reaffirmed the conclusions scientists had previously predicted about the evolution of radio galaxies and made my own predictions as well.
Cosmic Ray Detector Files
For anyone who wants / needs the files for the cosmic ray detector, here they are in one handy zip file (zip is in .rar format). Included are the following:
1) EQUIP (user interface for the detector) as zip file - no installation required; just unzip and go.
2) rxtxserial.dll - a small file needed for people running 64 bit Java on their computer - replace the old file in the EQUIP folder with this one.
2) SiLabs software driver for the DAQ USB connection - installation required; you may need administrator privileges for this. Both Windows 7/8/10 and Windows XP versions are included.
3) Plateauing Instructions - both the PPT instructions and the Excel spreadsheet for entering data are included.
Link to create an elab account and/or QuarkNet account
Teachers may want to request an elab account (for use with the CRMDs as well as the CMS elab and LIGO elabs) or a QuarkNet account. We use the latter to post and share documents within the group and for all of QuarkNet.
