Núria Torres-Albà?

Núria Torres-Albà is a PostDoctoral Fellow at Clemson University in Clemson, USA. Her research is focused on active galactic nuclei (AGN) and their surroundings across the electromagnetic spectrum. In particular, she has worked on X-ray analysis of luminous infrared galaxies (LIRGs) and Compton-thick AGN in the local Universe, as well as the modeling of gamma-ray emission produced in the interactions between AGN jets and obstacles.
She obtained her PhD in 2019 at the University of Barcelona, in Spain, and has been working at Clemson University ever since.

Stefano Marchesi

Stefano Marchesi is an Adjunct Professor at Clemson University and also holds a Researcher in Astrophysics at the University of Bologna, Italy. His research focuses on accreting supermassive black holes in the center of galaxies, and particularly on the most obscured among these sources.
He obtained his PhD in Astronomy in 2015 at the University of Bologna, Italy. During his PhD years, he was a visiting graduate student at Dartmouth College (Hanover, NH, USA), the Yale Center for Astronomy and Astrophyisics (New Haven, CT, USA) and at the Center for Astrophysics | Harvard & Smithsonian (Cambridge, MA, USA). After graduating, he was a PostDoctoral Fellow at Clemson University (SC, USA), from 2016 to 2019.

Xiurui Zhao

Xiurui Zhao was a PhD student of Physics and Astronomy department at Clemson University (Clemson, USA) graduated in Aug. 2021. He joined Dr. Ajello’s group in 2017. He obtained his Bachelor degree in Physics at Lanzhou University (Lanzhou, China) in 2016. Now he is a postdoctoral research Fellow at the Center for Astrophysics | Harvard & Smithsonian (Cambridge, USA). His research focus on the physics of the active galactic nuclei (AGN) in X-rays. Here is his Personal Website.

Ross Silver

Ross Silver is a third year graduate student at Clemson University in Clemson, USA. His research is focused on X-ray analysis of active galactic nuclei (AGN) and the obscuring material surrounding them. He has also worked on X-ray to gamma-ray source association in the Third Fermi-LAT Catalog of High-Energy Sources (3FHL).
He obtained his undergraduate degree in Physics at Gettysburg College in Gettysburg, USA. Ross joined Dr. Marco Ajello’s group in 2018.

Marco Ajello

Marco Ajello is an Astrophysicist with strong interests in astro-particle physics and cosmology. His interests lie in the evolution of super-massive black holes and galaxies, the generation of truly diffuse backgrounds (from infrared to gamma rays), high-energy transients and high-energy sources in general. Recently, he turned his attention to the evolution of the extragalactic background light and the role of the first stars during the epoch of re-ionization. He works with a number of instruments and telescopes both from the ground and in space, but his all-time favorites are the NASA missions FermiSwift, and NuSTAR.

Andrealuna Pizzetti

Andrealuna Pizzetti is a second year graduate student of Physics and Astronomy department at Clemson University in Clemson, USA. Her research focuses on X-ray analysis and modeling of obscured active galactic nuclei (AGN) and on the study of the variability of their tori properties over time using different models.
She obtained her Bachelor’s degree in Astronomy at the University of Bologna in 2018 and she joined Dr. Ajello group in 2020.

Alberto Traina

Alberto Traina is a second year PhD student in Astrophysics and Cosmology at the University of Bologna (Italy) in affiliation with the Italian National Institute for Astrophysics (INAF-OAS). His main interest is in extragalactic astrophysics of small and large galaxy samples, in the near and distant Universe. In his works he makes use of synergies between different type of observations in different parts of the electromagnetic spectrum (e.g., infrared and X-ray) to investigate both the physical and statistical properties of AGN samples.

He obtained his Bachelor degree in Astronomy in 2018 and a Master degree in Astrophysics and Cosmology in 2020, both at the University of Bologna.

Isaiah Cox

Isaiah Cox is a third year graduate student at Clemson University in Clemson, USA. His research involves the X-ray analysis of obscured active galactic nuclei (AGN). In particular, he is working on a method to detect variability in obscuration, and is studying how this variability can affect the way we interpret AGN spectra.

He obtained his bachelor’s degrees in Physics and Mathematics at East Tennessee State University in 2020. He joined Dr. Ajello’s group in 2021.
