The summer of my sophomore year as an undergraduate, I was part of a four-member research group that worked under Professor Eilat Glikman’s guidance on evaluating and utilizing new selection criteria for dust-reddened quasars. The complete study presents a comprehensive analysis of 147 active galactic nuclei (AGN) identified in the SDSS Stripe 82 region using WISE infrared selection criteria. The AGN are categorized into three types: 57 unobscured Type-1, 69 obscured Type-2, and 21 reddened Type-1 AGN, based on their spectral properties. By examining their X-ray, optical, and infrared luminosities, the study explores correlations between different luminosity indicators and assesses the level of obscuration in these AGN. The findings highlight variations in AGN luminosity functions and suggest different evolutionary paths for obscured and unobscured AGN. This research provides valuable insights into the nature of quasars and their role in the cosmic history of black hole growth and galaxy evolution.

Undergraduate Honors Thesis: Probing into quasar/galaxy co-evolution using the OSIRIS data

Milena Crnogorčević, Advisor: Prof. Eilat Glikman

As part of my undergraduate senior thesis, I conducted research in post-merger galaxy dynamics. I analyzed data from the OSIRIS integral field spectrograph (Keck) combined with Laser Guide-Star Adaptive Optics (LGS) to better understand the evolution of moderately dust-reddened quasars as well as their hosting galaxies.

Summer REU: Edge Expansion for Scalar Casimir Energies

Milena Crnogorčević, Advisor: Prof. Noah Graham

Under the guidance of Professor Noah Graham, I carried out research concerning the edge expansion for scalar Casimir energies. Presented with electromagnetic results for a configuration consisting of an oblate spheroid facing a perfectly conducting plane, I proposed a less computationally expensive analysis of the Casimir force using a scalar field theory. This approach required modifications and improvements of the existing code written in C that computes spheroidal functions. I presented this project at the Middlebury Summer Symposium in 2016, see the poster below.
