About the project team

We'd love to have you as part of our team. Please contact us with scientific projects if you would like to join.

Core team

Koss, Michael (Eureka Scientific)  

Dr. Koss' main research focus is how black holes grow and interact with their host galaxy. He is particularly interested in studying obscured black hole growth and merging galaxies using large samples of nearby AGN. He has led over 40 ground and space based proposals to study Swift BAT selected AGN in the UV/optical/IR/submillimeter/radio with large programs with Chandra in the X-rays, APEX in the submillimeter, and Keck using NIR adaptive optics. His goal in the BASS project is to encourage other researchers to pool their expertise to identify unique scientific questions and test much of the AGN science done in the last 30 years with a large sample (>1000) that is sensitive to obscured AGN and has reliable measurements of black hole masses and accretion rates. As part of the core team he sets up the projects, telecons, and the BASS slack group.

Ricci, Claudio (Universidad Diego Portales)  

Dr. Ricci's research is mainly focussed on the structure of the gas and dust surrounding supermassive black holes, and on how this material evolves with the properties of the AGN and those of the host galaxy. Within BASS he is in charge of the X-ray spectroscopy of all Swift/BAT AGN, and on the study of absorption properties of AGN.

Trakhtenbrot, Benny (Tel Aviv University)  

Dr. Trakhtenbrot is interested in the cosmic growth of super-massive black holes, the radiation that emerges from this process, and how these may be related to the host galaxies. As part of the BASS core team, Dr. Trakhtenbrot contributed to optical spectral analysis, and particularly black hole mass and accretion rate measurements, as well as general project oversight.

Oh, Kyuseok (Korea Astronomy and Space Science Institute)  

Dr. Oh's research interests lie in the field of galaxy formation and evolution, with a particular focus on the active galactic nuclei with supermassive black holes using ground optical telescopes as well as space based high-energy X-ray instruments. As a core member of the BASS project, Dr. Oh analysed acquired optical spectral data, proposed successful optical spectroscopic proposals, and performed follow-up spectral line measurements. More optical data analysis for measuring black hole mass, Eddington accretion rate and emission line statistics is currently in progress.

Schawinski, Kevin (ETH Zurich)  

Professor Schawinski's main research interests are the co-evolution of galaxies and supermassive black holes; how, when and why the energy liberated by accreting black holes at the centers of galaxies regulates the evolution of their host galaxies and alters their evolutionary trajectories. Which black hole accretion modes are important and how they inject energy into the interstellar medium of their host galaxies. Where supermassive black holes come from; which mechanisms lead to the formation of the first black holes, what their first growth episodes are like and whether black hole formation is limited to the early universe. He is also active in citizen science, the direct involvement of the public in scientific research.

Lamperti, Isabella (University College London)  

Isabella is interested in the study of AGN in the local Universe and the possibility to use near-infrared spectroscopy to identify AGN and measure black hole masses for obscured AGN. As part of the BASS project, she contributed to the analysis of the optical spectra by measuring the emission line fluxes, stellar velocity dispersion and black hole masses for narrow lines AGN. She also took care of the near-infrared spectroscopic part of the survey.

Urry, Meg (Yale University)  

Meg Urry is Director of the Yale Center for Astronomy and Astrophysics and served as Chair of the Yale Physics Department from 2007 to 2013. She is currently Past President of the American Astronomical Society (the last in a 4-year term). Her scientific research focuses on active galaxies, which host accreting supermassive black holes in their centers; she has published over 270 refereed research articles on supermassive black holes and galaxies and was identified as a "Highly Cited Author" by Thomson Reuters.

Powell, Meredith (Yale University)  

Merry's research interests include the growth of supermassive black holes and how they coevolve with the galaxies and dark matter halos that host them. For the BASS survey she has contributed to the spectroscopic follow-up observations of the sample, and has lead the analysis of their spatial clustering in order to characterize the large-scale environments of AGN.
