Description
Chicago, the third largest city in the United States, is frequently in the national media's spotlight for negative news such as violence or failed gun laws. The city is hardly ever talked about in a positive light. This study aims to inform and educate outsiders of what the city is like through the perspective lens of Chicago residents. To grasp a general understanding of Chicago, this creative project was completed through a narrative and interview-driven podcast series and split up into different topic categories. These categories were Chicago food, Chicago neighborhoods, Chicago's Southside, and Chicago sports. These topic areas are some of the things Chicago is most known for and give an adequate representation of what the city is like. Researching and putting this creative project into a podcast form proved how podcasts can be an alternative to in-depth and long-form journalism projects. The Chicago food episode called "Harold's v. Uncle Remus" explains the delicious food culture and showed two of the popular black restaurant chains that cater to the city. These two chicken spots are always a hot topic in heated debates of what place has the best chicken. The neighborhoods episode called "Won't You Be My Neighbor" highlights some of Chicago's interesting neighborhoods that tourists may not have on their attractions lists. This episode talks about the Pill Hill, Printers Row, and Little Italy neighborhoods, which all have unique histories. "Southside With You" explores the infamous region of Chicago, tells its history, and gives a theory as to why it continues to be the area it is known for in the media. Lastly, the sports episode "Sports: A History Lesson" is a full interview with a Chicago resident who has been a Chicago sports fan since the mid-60s and who has experienced the effects of racial divisions in sports. The episodes give only a peak of what the large city is like, but they demonstrate that Chicago is not this scary place, but a place with a complicatedly fascinating history.

Description
Radio astronomy is a subfield in astronomy that deals with objects emitting frequencies around 10 MHz to 100 GHz. The Low Frequency Array (LOFAR) is a array of radio antennas in Europe that can reach very low frequencies, roughly between 10-240 MHz. Our project was to image and clean a field from LOFAR. The data was a 10 degree square in the sky centered at a right ascension of 10:19:34.608 and a declination +49.36.52.482. It was observed for 600 seconds at 141 MHz. To clean the field, we had to flag and remove any stations that were not responding. Using a program called FACTOR, we cleaned the image and reduced the residuals. Next we checked the validity of our sources. We checked positional offsets for our sources using the TGSS survey at 150 MHz, and corrected the declination of our LOFAR sources by a factor of 0.0002 degrees. We also fixed the LOFAR fluxes by a factor of 1.15. After this systematic check, we calculated the spectral index of our sources using the FIRST survey at 1435 MHz. We plotted this spectral index against LOFAR flux as well as redshift of the sources, and compared these to literature.

Description
I examine the effects of metallicity on solar mass stellar evolution, trying to replicate a previous result in Windhorst et.al., 2018, in which a zer metallicity solar mass star did not reach the AGB, and thus may turn into a helium white dwarf. In trying to replicate this result, I used the M.E.S.A. stellar evolution code and was unable to reproduce this result. While M.E.S.A has undergone several updates since the previous result was obtained, more current evidence suggests that this may have been a one-time occurrence, as no helium white dwarfs were produced for low-metallicity models. Nonetheless, interesting results were obtained, including a lowest metallicity value for which CNO burning does not significantly contribute during the main sequence, 1 −10 Z , which produces noticeable effects on post main sequence evolution. All models are run with no rotation, one solar mass, and a series of MESA parameters kept constant, with the only exception being metallicity. Any metallicity value listed as Nd −10 is an absolute mass fraction, and Z is relative to solar metallicity, 2d*10 −2 .
