Publications
117 publications in refereed journals (32 first author).
Dr. T. Yaqoob has published papers on various topics including observational and theoretical work on physical processes in black-hole accretion disk systems and their environment (mostly active galactic nuclei AGN and quasars but including X-ray binary systems); blazars (including TeV observations); X-ray and UV absorption and photoionized outflows and inflows in AGN and quasars; high spectral-resolution X-ray spectroscopy; power spectra, spectral and temporal variability; normal and starburst galaxies; AGN unification; low-luminosity AGN; X-ray background; coordinated multi-wavelength and multi-mission monitoring campaigns of AGN; a high-redshift cluster of galaxies; absorption in the warm/hot intergalactic medium (WHIGM); statistics; analysis methods; numerical and Monte Carlo modeling. Dr. Yaqoob has incorporated and documented several such models into spectral fitting packages such as XSPEC. In particular, Dr. Yaqoob has been involved with state-of-the-art development of models for fitting X-ray data in order to elucidate the physics in the close vicinity of black holes and strong gravity, and to understand the intercation of X-rays with obscuring matter that often surronds the putative supermassive black holes in the central engines of active galaxies.
