My astrophysics research


I study Active Galactic Nuclei (AGN), X-ray binaries, nebular lines in star forming  galaxies, and  compact groups of galaxies- not necessarily in this order!

Questions I and my collaborators are exploring include:
  • What do key features in X-ray spectra of AGN and X-ray binaries tell us about their physics? 
Collaborators 🤔🎭🌟 Tahir Yaqoob, Stephanie LaMassa, Katja Pottschmidt, Andy Ptak, Jane Turner, Jörn Wilms, Mihoko Yukita
🌀🌀 Highlights ⭐⭐
🚩 We predict analytically and computationally the large equivalent widths for FeKα lines at kpc scales from central AGN in Tzanavaris, Yaqoob & LaMassa, 2023PhRvD.108l3037T
🚩 See our comprehensive MYTORUS modeling of NGC 4388 in Yaqoob, Tzanavaris & LaMassa, 2023MNRAS.522..394Y
🚩 See Tzanavaris et al 2021ApJ...922...85T for "Compton-thin" AGN - but not globally Compton-thin!
🚩 See what we deduce for the X-ray reprocessor in Galactic X-ray binaries in Tzanavaris & Yaqoob,  2018ApJ...855...25T 


  • What powers the prominent nebular emission lines in so-called He II and Wolf Rayet galaxies
Collaborators 🤔🤷Antara Basu-Zych, Kristen Garofali, Ben Johnson

🌀🌀 Latest results ⭐⭐
🚩 See how our Simple X-ray Populations can power these lines in Garofali et al., 2024ApJ...960...13G


  • What is the origin of X-ray luminosity excess in late-type galaxies in compact groups of galaxies?  
Collaborators 🤝🤔Sarah Gallagher, Ann Hornschemeier, Kelsey Johnson, Jane Charlton, Mihoko Yukita
🌀🌀 Unexplained ⭐⭐
🚩 Read about our discovery of the X-ray luminosity excess in compact groups in Tzanavaris et al., 2016ApJ...817...95T
