Research Highlights
Probing Physical Distances using Light Echoes:
I use the reverberation mapping technique to study the inner environments of quasars. This technique involves monitoring the variable quasar light curves to measure the time delays between changes in the continuum emission from the accretion disk and the emission from the surrounding gas clouds. These delays provide clues about the structure and distances of these regions.
Intensive Multi-Wavelength Reverberation Mapping Campaign
I take an iterative approach in my work to ensure the final result aligns with your creative vision and reflects your unique brand identity. We’ll work together to refine and fine-tune your site’s design, leaving no detail overlooked.
SDSS-RM and Black-Hole Mapper Programs
SDSS-RM (Sloan Digital Sky Survey Reverberation Mapping) and Black Hole Mapper are two closely related programs designed to study supermassive black holes in quasars. Both SDSS-RM and Black Hole Mapper are crucial for our understanding of supermassive black holes and their role in the evolution of galaxies. By providing accurate measurements of black hole masses and properties, these programs help scientists test theories of black hole formation and growth.
Main Projects and Collaborations
AGN Space Telescope and Optical Reverberation Mapping Program 2
AGN STORM 2 is an intensive, multi-wavelength reverberation mapping campaign designed to study the structure and dynamics of active galactic nuclei, Mrk 817. This program is a follow-up to the highly successful AGN STORM campaign on NGC5548. AGN STORM 2 utilizes a variety of telescopes and instruments to observe AGN across a wide range of wavelengths, from X-rays to infrared.This allows for a comprehensive understanding of the complex processes at play.
LSST AGN Science Collaboration
The LSST AGN Science Collaboration (LSST AGN SC) is a group of astronomers dedicated to leveraging the capabilities of the Legacy Survey of Space and Time (LSST) to study active galactic nuclei (AGN). LSST is a ground-based telescope that will conduct a ten-year survey of the entire visible sky, providing unprecedented depth and breadth of astronomical data. The key objectives of the LSST AGN SC is to perform AGN Identification and Characterization, AGN Variability Studies, and study of AGN demographic.
