HD 62542: Probing the Bare, Dense Core of a Translucent Interstellar Cloud

Posted by klaurent Chicago

Kavli Affiliate: Donald G. York | First 5 Authors: Daniel E. Welty, Paule Sonnentrucker, Theodore P. Snow, Donald G. York, | Summary: We discuss the interstellar absorption from many atomic and molecular species seen in high-resolution $HST$/STIS UV and high-S/N optical spectra of the moderately reddened B3-5~V star HD~62542. This remarkable sight line exhibits both […]

Dynamical evolution of cosmic supermassive binary black holes and their gravitational wave radiation

Posted by klaurent Peking

Kavli Affiliate: Qingjuan Yu | Summary:We investigate the evolution of supermassive binary black holes (BBHs) in galaxies with realistic property distributions and the gravitational-wave (GW) radiation from the cosmic population of these BBHs. We incorporate a comprehensive treatment of the dynamical interactions of the BBHs with their environments by including the effects of galaxy triaxial […]
